第17章通用串行总线设备控制器 (S08USBV1)17.1 介绍这一章描述了通用串行总线设备控制器 (S08USBV1) 模块,它基于通用串行总线规格版本2.0。

该USB 总线设计目的是替代已经存在的用于PC 机外围设备的RS-232, PS/2, 和 IEEE 1284 总线。

这种S08USBV1 模块提供单片全速(12 Mbps)USB 设备应用的解决方案,而且集成了必需的带有串行接口引擎(SIE )的收发器,3.3-V 调节器, 端点RAM 和其他控制逻辑。

17.1.1 时钟要求S08USBV1需要两个时钟源,一个是24 MHz 总线时钟和一个48 MHz 基准时钟。

它的48 MHz 时钟是直接来自MCGOUT 。

为了获得48 MHz 的时钟速率, MCG 必需被恰当地配置成PLL 使能的外部(PEE) 模式,外接一晶振。

对于USB 操作,例如MCG 配置使用PEE 模式包括: • 2 MHz 晶振 – RDIV = 000 , VDIV = 0110 • 4 MHz 晶振 – RDIV = 001 , VDIV = 011017.1.2 在USB 挂起模式的电流消耗在USB 挂起模式,USB 设备的电流消耗被限制在500 μA 。

当USB 设备进入挂起模式,为了符合USB 挂起模式的电流消耗要求,固件通常进入停止3模式。

注意:允许LVD 将增加在停止模式3下的电流消耗。

因此,为了能满足USB 挂起模式的要求,在进入停止模式3前要禁止LVD 。

F RE E-TE C H飞锐泰克17.1.3 内部3.3V 稳压器如果使用一个外部3.3-V 调节器作为输入给V USB33 (仅仅当USBVREN = 0), 供应电压,V DD , 必须不能低于输入给V USB33引脚的电压。

如果使用内部3.3-V 调节器 (USBVREN = 1), 确保不要把外部供应电压连接到V USB33 引脚。

GENERAL DESCRIPTIONThe W39V080FA is an 8-megabit, 3.3-volt only CMOS flash memory organized as 1M × 8 bits. For flexible erase capability, the 8Mbits of data are divided into 16 uniform sectors of 64 Kbytes. The device can be programmed and erased in-system with a standard 3.3V power supply. A 12-volt VPP is required for accelerated program. The unique cell architecture of the W39V080FA results in fast program/erase operations with extremely low current consumption. This device can operate at two modes, Programmer bus interface mode and FWH bus interface mode. As in the Programmer interface mode, it acts like the traditional flash but with a multiplexed address inputs. But in the FWH interface mode, this device complies with the Intel FWH specification. The device can also be programmed and erased using standard EPROM programmers.2.

FUNCTIONAL DESCRIPTION6.1 Interface Mode Selection and DescriptionThis device can operate in two interface modes, one is Programmer interface mode, and the other is FWH interface mode. The IC pin of the device provides the control between these two interface modes. These interface modes need to be configured before power up or return from #RESET. When IC pin is set to high state, the device will be in the Programmer mode; while the IC pin is set to low state (or leaved no connection), it will be in the FWH mode. In Programmer mode, this device just behaves like traditional flash parts with 8 data lines. But the row and column address inputs are multiplexed. The row address are mapped to the higher internal address A[19:11]. And the column address are mapped to the lower internal address A[10:0]. For FWH mode, It complies with the FWH Interface Specification. Through the FWH[3:0] and FWH4 to communicate with the system chipset .6.2 Read (Write) ModeIn Programmer interface mode, the read (write) operation of the W39V080FA is controlled by #OE (#WE). The #OE (#WE) is held low for the host to obtain (write) data from (to) the outputs (inputs). #OE is the output control and is used to gate data from the output pins. The data bus is in high impedance state when #OE is high. As for in the FWH interface mode, the read or write is determined by the "bit 0 & bit 1 of START CYCLE ". Refer to the FWH cycle definition and timing waveforms for further details.6.3 Reset OperationThe #RESET input pin can be used in some application. When #RESET pin is at high state, the device is in normal operation mode. When #RESET pin is at low state, it will halt the device and all outputs will be at high impedance state. As the high state re-asserted to the #RESET pin, the device will return to read or standby mode, it depends on the control signals.6.4 Accelerated Program OperationThe device provides accelerated program operations through the ACC function. This function is primarily intended to allow a faster manufacturing throughput in the factory.6.5 Boot Block Operation and Hardware Protection at Initial- #TBL & #WPThere is a hardware method to protect the top boot block and other sectors. Before power on programmer, tie the #TBL pin to low state and then the top boot block will not be programmed/erased. If #WP pin is tied to low state before power on, the other sectors will not be programmed/erased.In order to detect whether the boot block feature is set on or not, users can perform software command sequence: enter the product identification mode (see Command Codes for Identification/Boot Block Lockout Detection for specific code), and then read from address FFFF2(hex). You can check the DQ2/DQ3 at the address FFFF2 to see whether the #TBL/#WP pin is in low or high state. If the DQ2 is “0”, it means the #TBL pin is tied to high state. In such condition, whether boot block can be programmed/erased or not will depend on software setting. On the other hand, if the DQ2 is “1”, it means the #TBL pin is tied to low state, then boot block is locked no matter how the software is set. Like the DQ2, the DQ3 inversely mirrors the #WP state. If the DQ3 is “0”, it means the #WP pin is in high state, then all the sectors except the boot block can be programmed/erased. On the other hand, if the DQ3 is “1”, then all the sectors except the boot block are programmed/erased inhibited.To return to normal operation, perform a three-byte command sequence (or an alternate single-byte command) to exit the identification mode. For the specific code, see Command Codes for Identification/Boot Block Lockout Detection.Publication Release Date: Dec. 13, 2005W39V080FA6.6 Sector Erase CommandSector erase is a six bus cycles operation. There are two "unlock" write cycles, followed by writing the "set-up" command. Two more "unlock" write cycles then follows by the Sector erase command. The Sector address (any address location within the desired Sector) is latched on the rising edge of R/#C in programmer mode, while the command (30H) is latched on the rising edge of #WE.Sector erase does not require the user to program the device prior to erase. When erasing a Sector, the remaining unselected sectors are not affected. The system is not required to provide any controls or timings during these operations.The automatic Sector erase begins after the erase command is completed, right from the rising edge of the #WE pulse for the last Sector erase command pulse and terminates when the data on DQ7, Data Polling, is "1" at which time the device returns to the read mode. Data Polling must be performed at an address within any of the sectors being erased.Refer to the Erase Command flow Chart using typical command strings and bus operations.6.7 Program OperationThe W39V080FA is programmed on a byte-by-byte basis. Program operation can only change logical data "1" to logical data "0." The erase operation, which changed entire data in main memory and/or boot block from "0" to "1", is needed before programming.The program operation is initiated by a 4-byte command cycle (see Command Codes for Byte Programming). The device will internally enter the program operation immediately after the byte-program command is entered. The internal program timer will automatically time-out (9μS typ.-T BP) once it is completed and then return to normal read mode. Data polling and/or Toggle Bits can be used to detect end of program cycle.6.8 Dual BIOSThe W39V080FA provides a solution for Dual-BIOS application. In FWH mode, when D/#F is low, the device functions as a full-chip partition of 8M-bit which address ranges from FFFFFh to 00000h with A[19:0]. If D/#F is driven high, the device functions as a dual-block partition that each block consists of 4M-bit. For dual-block partition, there is only one 4M-bit block, either upper or lower, can be accessed. The U/#L pin selects either upper or lower 4M-bit block and its address ranges from 7FFFFh to 00000h with A[19:0]. When U/#L is low, the lower 4M-bit block will be selected; while, U/#L is high, the upper 4M-bit block will be selected.6.9 Hardware Data ProtectionThe integrity of the data stored in the W39V080FA is also hardware protected in the following ways:(1) Noise/Glitch Protection: A #WE pulse of less than 15 nS in duration will not initiate a write cycle.(2) V DD Power Up/Down Detection: The programming and read operation are inhibited when V DD isless than 2.0V typical.(3) Write Inhibit Mode: Forcing #OE low or #WE high will inhibit the write operation. This preventsinadvertent writes during power-up or power-down periods.W39V080FA6.10 Write Operation StatusThe device provides several bits to determine the status of a program or erase operation: DQ5, DQ6, and DQ7. Each of DQ7 and DQ6 provides a method for determining whether a program or erase operation is complete or in progress. The device also offers a hardware-based output signal, RY/#BY in programmer mode, to determine whether an Embedded Program or Erase operation is in progress or has been completed.6.10.1 DQ7: #Data PollingThe #Data Polling bit, DQ7, indicates whether an Embedded Program or Erase algorithm is in progress or completed. Data Polling is valid after the rising edge of the final #WE pulse in the command sequence.During the Embedded Program algorithm, the device outputs on DQ7 and the complement of the data programmed to DQ7. Once the Embedded Program algorithm has completed, the device outputs the data programmed to DQ7. The system must provide the program address to read valid status information on DQ7. If a program address falls within a protected sector, #Data Polling on DQ7 is active for about 1μS, and then the device returns to the read mode.During the Embedded Erase algorithm, #Data Polling produces “0” on DQ7. Once the Embedded Erase algorithm has completed, #Data Polling produces “1” on DQ7. An address within any of the sectors selected for erasure must be provided to read valid status information on DQ7.After an erase command sequence is written, if all sectors selected for erasing are protected, #Data Polling on DQ7 is active for about 100μS, and then the device returns to the read mode. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. However, if the system reads DQ7 at an address within a protected sector, the status may not be valid.Just before the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously with DQ0-DQ6 while Output Enable (#OE) is set to low. That is, the device may change from providing status information to valid data on DQ7. Depending on when it samples the DQ7 output, the system may read the status or valid data. Even if the device has completed the program or erase operation and DQ7 has valid data, the data outputs on DQ0-DQ6 may be still invalid. Valid data on DQ7-DQ0 will appear on successive read cycles.6.10.2 RY/#BY: Ready/#BusyThe RY/#BY is a dedicated, open-drain output pin which indicates whether an Embedded Algorithm is in progress or complete. The RY/#BY status is valid after the rising edge of the final #WE pulse in the command sequence. Since RY/#BY is an open-drain output, several RY/#BY pins can be tied together in parallel with a pull-up resistor to V DD.When the output is low (Busy), the device is actively erasing or programming. When the output is high (Ready), the device is in the read mode or standby mode.6.10.3 DQ6: Toggle BitToggle Bit on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete. Toggle Bit I may be read at any address, and is valid after the rising edge of the final #WE pulse in the command sequence (before the program or erase operation), and during the sector erase time-out.During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause DQ6 to toggle. The system may use either #OE to control the read cycles. Once the operation has completed, DQ6 stops toggling.Publication Release Date: Dec. 13, 2005W39V080FAAfter an erase command sequence is written, if all sectors selected for erasing are protected, DQ6toggles for about 100μS, and then returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selectedsectors which are protected.The system can use DQ6 to determine whether a sector is actively erasing. If the device is activelyerasing (i.e., the Embedded Erase algorithm is in progress), DQ6 toggles. If a program address fallswithin a protected sector, DQ6 toggles for about 1 μs after the program command sequence is written,and then returns to reading array data.6.10.4 DQ5: Exceeded Timing LimitsDQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit.DQ5 produces “1” under these conditions which indicates that the program or erase cycle was not successfully completed.The device may output “1” on DQ5 if the system tries to program “1” to a location that was previously programmed to “0.” Only the erase operation can change “0” back to “1.” Under this condition, thedevice stops the operation, and while the timing limit has been exceeded, DQ5 produces “1.”Under both these conditions, the system must hardware reset to return to the read mode.6.11 Identification Input pin ID[3:0]These pins are part of mechanism that allows multiple parts to be used on the same bus. The bootdevice should be 0000b. And all the subsequent parts should use the up-count strapping.6.12 RegisterThere are three kinds of registers on this device, the General Purpose Input Registers, the Block LockControl Registers and Product Identification Registers. Users can access these registers through respective address in the 4Gbytes memory map. There are detail descriptions in the sections below.6.12.1 General Purpose Inputs RegisterThis register reads the FGPI[4:0] pins on the W39V080FA.This is a pass-through register which canread via memory address FFBC0100(hex).

User can clear or set the write lock bit anytime as long as the lock down bit is not set.Write LockThis is the default state of blocks upon power up. Before any program or erase to the specified block, user should clear the write lock bit first. User can clear or set the write lock bit anytime as long as the lock down bit is not set. The write lock function is in conjunction with the hardware protect pins, #WP & TBL. When hardware protect pins are enabled, it will override the register block locking functions and write lock the blocks no matter how the status of the register bits. Reading the register bit will not reflect the status of the #WP or #TBL pins.Lock DownThe default state of lock down bit for any block is unlocked. This bit can be set only once; any further attempt to set or clear is ignored. Only the reset from #RESET or #INIT can clear the lock down bit. Once the lock down bit is set for a block, then the write lock bit & read lock bit of that block will not be set or cleared, and keep its current state.6.12.3 Product Identification RegistersThere is an alternative software method to read out the Product Identification in both the Programmer interface mode and the FWH interface mode. Thus, the programming equipment can automatically matches the device with its proper erase and programming algorithms.In the full-chip(8Mb) FWH interface mode, a read from FFBC, 0000(hex) can output the manufacturer code, DA(hex). A read from FFBC, 0001(hex) can output the device code, D3(hex).For Dual-BIOS(4Mbx2) FWH mode , a read from FFBC, 0000(hex) can output the manufacturer code, DA(hex). A read from FFBC,0001(hex) can output the device code 93(hex).In the software access mode, a JEDEC 3-byte command sequence can be used to access the product ID for programmer interface mode. A read from address 0000(hex) outputs the manufacturer code, DA(hex). A read from address 0001(hex) outputs the device code, D3(hex).” The product ID operation can be terminated by a three-byte command sequence or an alternate one-byte command sequence (see Command Definition table for detail).W39V080FAPublication Release Date: Dec. 13, 20056.13 Table of Operating Modes6.13.1 Operating Mode Selection - Programmer ModeMODE PINS#OE#WE#RESETADDRESSDQ.Read V IL V IH V IH AIN Dout Write V IH V ILV IHAIN DinStandby X X V IL X High ZWrite Inhibit V IL X V IH X High Z/DOUT X V IH V IH X High Z/DOUTOutput DisableV IH X V IH X High Z6.13.2 Operating Mode Selection - FWH ModeOperation modes in FWH interface mode are determined by "START Cycle" when it is selected.

single-ended analog signal multiplexer.A particular input channel is selected by using the address decoder.Table1shows the input states for the address lines to select any channel.The address is latched into the decoder on the low-to-high transition of the address latch enable signal.Table1.Analog Channel SelectionADDRESS LINESELECTED ANALOGCHANNEL C B AIN0L L LIN1L L HIN2L H LIN3L H HIN4H L LIN5H L HIN6H H LIN7H H HCONVERTER CHARACTERISTICSThe ConverterThe heart of this single chip data acquisition system is its8-bit analog-to-digital converter.The converter is designed to give fast,accurate,and repeatable conversions over a wide range of temperatures.The converter is partitioned into3major sections:the256R ladder network,the successive approximation register,and the comparator.The converter's digital outputs are positive true.The256R ladder network approach(Figure3)was chosen over the conventional R/2R ladder because of its inherent monotonicity,which ensures no missing digital codes.Monotonicity is particularly important in closed loop feedback control systems.A non-monotonic relationship can cause oscillations that will be catastrophic for the system.Additionally,the256R network does not cause load variations on the reference voltage.The bottom resistor and the top resistor of the ladder network in Figure3are not the same value as the remainder of the network.The difference in these resistors causes the output characteristic to be symmetrical with the zero and full-scale points of the transfer curve.The first output transition occurs when the analog signal has reached+½LSB and succeeding output transitions occur every1LSB later up to full-scale.The successive approximation register(SAR)performs8iterations to approximate the input voltage.For any SAR type converter,n-iterations are required for an n-bit converter.Figure4shows a typical example of a3-bit converter.In the ADC0808,ADC0809,the approximation technique is extended to8bits using the256R network.The A/D converter's successive approximation register(SAR)is reset on the positive edge of the start conversion start pulse.The conversion is begun on the falling edge of the start conversion pulse.A conversion in process will be interrupted by receipt of a new start conversion pulse.Continuous conversion may be accomplished by tying the end-of-conversion(EOC)output to the SC input.If used in this mode,an external start conversion pulse should be applied after power up.End-of-conversion will go low between0and8clock pulses after the rising edge of start conversion.The most important section of the A/D converter is the comparator.It is this section which is responsible for the ultimate accuracy of the entire converter.It is also the comparator drift which has the greatest influence on the repeatability of the device.A chopper-stabilized comparator provides the most effective method of satisfying all the converter requirements.The chopper-stabilized comparator converts the DC input signal into an AC signal.This signal is then fed through a high gain AC amplifier and has the DC level restored.This technique limits the drift component of the amplifier since the drift is a DC component which is not passed by the AC amplifier.This makes the entire A/D converter extremely insensitive to temperature,long term drift and input offset errors.Copyright©1999–2013,Texas Instruments Incorporated Submit Documentation Feedback5ADC0808-N,ADC0809-NSNAS535H–OCTOBER1999–REVISED Figure6shows a typical error curve for

Documentation Feedback 9ADC0808-N,ADC0809-NSNAS535H–OCTOBER1999–REVISED APPLICATIONS INFORMATIONOPERATIONRATIOMETRIC CONVERSIONThe ADC0808,ADC0809is designed as a complete Data Acquisition System(DAS)for ratiometric conversion systems.In ratiometric systems,the physical variable being measured is expressed as a percentage of full-scale which is not necessarily related to an absolute standard.The voltage input to the ADC0808is expressed by the equation•V IN=Input voltage into the ADC0808•V fs=Full-scale voltage•V Z=Zero voltage•D X=Data point being measured•D MAX=Maximum data limit•D MIN=Minimum data limit(1) A good example of a ratiometric transducer is a potentiometer used as a position sensor.The position of the wiper is directly proportional to the output voltage which is a ratio of the full-scale voltage across it.Since the data is represented as a proportion of full-scale,reference requirements are greatly reduced,eliminating a large source of error and cost for many applications.A major advantage of the ADC0808,ADC0809is that the input voltage range is equal to the supply range so the transducers can be connected directly across the supply and their outputs connected directly into the multiplexer inputs,(Figure11).Ratiometric transducers such as potentiometers,strain gauges,thermistor bridges,pressure transducers,etc., are suitable for measuring proportional relationships;however,many types of measurements must be referred to an absolute standard such as voltage or current.This means a system reference must be used which relates the full-scale voltage to the standard volt.For example,if V CC=V REF=5.12V,then the full-scale range is divided into 256standard steps.The smallest standard step is1LSB which is then20mV.RESISTOR LADDER LIMITATIONSThe voltages from the resistor ladder are compared to the selected into8times in a conversion.These voltages are coupled to the comparator via an analog switch tree which is referenced to the supply.The voltages at the top,center and bottom of the ladder must be controlled to maintain proper operation.The top of the ladder,Ref(+),should not be more positive than the supply,and the bottom of the ladder,Ref(−), should not be more negative than ground.The center of the ladder voltage must also be near the center of the supply because the analog switch tree changes from N-channel switches to P-channel switches.These limitations are automatically satisfied in ratiometric systems and can be easily met in ground referenced systems. Figure12shows a ground referenced system with a separate supply and reference.In this system,the supply must be trimmed to match the reference voltage.For instance,if a5.12V is used,the supply should be adjusted to the same voltage within0.1V.Figure11.Ratiometric Conversion System10Submit Documentation Feedback Copyright©1999–2013,Texas Instruments IncorporatedADC0808-N,ADC0809-N SNAS535H–OCTOBER1999–REVISED MARCH2013 The ADC0808needs less than a milliamp of supply current so developing the supply from the reference is readily accomplished.In Figure13a ground referenced system is shown which generates the supply from the reference.The buffer shown can be an op amp of sufficient drive to supply the milliamp of supply current and the desired bus drive,or if a capacitive bus is driven by the outputs a large capacitor will supply the transient supply current as seen in Figure14.The LM301is overcompensated to insure stability when loaded by the10μF output capacitor.The top and bottom ladder voltages cannot exceed V CC and ground,respectively,but they can be symmetrically less than V CC and greater than ground.The center of the ladder voltage should always be near the center of the supply.The sensitivity of the converter can be increased,(i.e.,size of the LSB steps decreased)by using a symmetrical reference system.In Figure15,a2.5V reference is symmetrically centered about V CC/2since the same current flows in identical resistors.This system with a2.5V reference allows the LSB bit to be half the size of a5V reference system.Figure12.Ground ReferencedConversion System Using Trimmed SupplyFigure13.Ground Referenced Conversion System withReference Generating V CC SupplyCopyright©1999–2013,Texas Instruments Incorporated Submit Documentation Feedback11ADC0808-N,ADC0809-NSNAS535H–OCTOBER1999–REVISED Figure14.Typical Reference and Supply CircuitR A=R B*Ratiometric transducersFigure15.Symmetrically Centered ReferenceCONVERTER EQUATIONSThe transition between adjacent codes N and N+1is given by:(2) The center of an output code N is given by:(3) The output code N for an arbitrary input are the integers within the range:Where:•V IN=Voltage at comparator input•V REF(+)=Voltage at Ref(+)•V REF(−)=Voltage at Ref(−)•V TUE=Total unadjusted error voltage(typically•V REF(+)÷512)(4) 12Submit Documentation Feedback Copyright©1999–2013,Texas Instruments IncorporatedADC0808-N,ADC0809-N SNAS535H–OCTOBER1999–REVISED MARCH2013ANALOG COMPARATOR INPUTSThe dynamic comparator input current is caused by the periodic switching of on-chip stray capacitances.These are connected alternately to the output of the resistor ladder/switch tree network and to the comparator input as part of the operation of the chopper stabilized comparator.The average value of the comparator input current varies directly with clock frequency and with V IN as shown in Figure8.If no filter capacitors are used at the analog inputs and the signal source impedances are low,the comparator input current should not introduce converter errors,as the transient created by the capacitance discharge will die out before the comparator output is strobed.If input filter capacitors are desired for noise reduction and signal conditioning they will tend to average out the dynamic comparator input current.It will then take on the characteristics of a DC bias current whose effect can be predicted conventionally.Typical Application*Address latches needed for8085and SC/MP interfacing the ADC0808to a microprocessorTable2.Microprocessor Interface TablePROCESSOR READ WRITE INTERRUPT(COMMENT)8080MEMR MEMW INTR(Thru RST Circuit)8085RD WR INTR(Thru RST Circuit)Z-80RD WR INT(Thru RST Circuit,Mode0)SC/MP NRDS NWDS SA(Thru Sense A)6800VMA•φ2•R/W VMA•φ•R/W IRQA or IRQB(Thru PIA)Copyright©1999–2013,Texas Instruments Incorporated Submit Documentation Feedback13ADC0808-N,ADC0809-NSNAS535H–OCTOBER1999–REVISED REVISION HISTORYChanges from Revision G(March2013)to Revision H Page •Changed layout of National Data Sheet to TI format (13)14Submit Documentation Feedback Copyright©1999–2013,Texas Instruments IncorporatedPACKAGING INFORMATION(1) The marketing status values are defined as follows:ACTIVE: Product device recommended for new designs.LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.NRND: Not recommended for new designs.

adc0808中文资料[整理版]

adc0808中文资料[整理版]11.2.4 典型的集成ADC芯片为了满足多种需要,目前国内外各半导体器件生产厂家设计并生产出了多种多样的ADC芯片。

仅美国AD公司的ADC产品就有几十个系列、近百种型号之多。

从性能上讲,它们有的精度高、速度快,有的则价格低廉。

从功能上讲,有的不仅具有A/D转换的基本功能,还包括内部放大器和三态输出锁存器;有的甚至还包括多路开关、采样保持器等,已发展为一个单片的小型数据采集系统。

尽管ADC芯片的品种、型号很多,其内部功能强弱、转换速度快慢、转换精度高低有很大差别,但从用户最关心的外特性看,无论哪种芯片,都必不可少地要包括以下四种基本信号引脚端:模拟信号输入端(单极性或双极性);数字量输出端(并行或串行);转换启动信号输入端;转换结束信号输出端。

除此之外,各种不同型号的芯片可能还会有一些其他各不相同的控制信号端。

选用ADC芯片时,除了必须考虑各种技术要求外,通常还需了解芯片以下两方面的特性。

(1)数字输出的方式是否有可控三态输出。

有可控三态输出的ADC芯片允许输出线与微机系统的数据总线直接相连,并在转换结束RD后利用读数信号选通三态门,将转换结果送上总线。

没有可控三态输出(包括内部根本没有输出三态门和虽有三态门、但外部不可控两种情况)的ADC芯片则不允许数据输出线与系统的数据总线直接相连,而必须通过I/O接口与MPU交换信息。

(2)启动转换的控制方式是脉冲控制式还是电平控制式。

对脉冲启动转换的ADC 芯片,只要在其启动转换引脚上施加一个宽度符合芯片要求的脉冲信号,就能启动转换并自动完成。

一般能和MPU配套使用的芯片,MPU的I/O写脉冲都能满足ADC芯片对启动脉冲的要求。

对电平启动转换的ADC芯片,在转换过程中启动信号必须保持规定的电平不变,否则,如中途撤消规定的电平,就会停止转换而可能得到错误的结果。

为此,必须用D触发器或可编程并行I/O接口芯片的某一位来锁存这个电平,或用单稳等电路来对启动信号进行定时变换。

Bridge Architecture Specification,Revision1.0PCI Special Interest Group1-800-433-5177I2C Peripherals for Microcontrollers Philips SemiconductorIntel ®i960®RX I/O Processor at 3.3Volts FunctionalOverview 2.0Functional Overview As indicated in Figure 1the 80960RX combines many features with the 80960JF to create an intelligent I/O processor.Subsections following the figure briefly describe the main features;for detailed functional descriptions,refer to the Intel ®i960®RP Microprocessor User’s Guide (272736).The PCI bus is an industry standard,high performance,low latency system bus that operates up to 132Mbyte/s.The 80960RX,a multi-function PCI device,is fully compliant with the PCI Local Bus Specification,Revision 2.1.Function 0is the PCI-to-PCI bridge unit;Function 1is the address translation unit.The PCI-to-PCI bridge unit is the connection path between two independent 32-bit PCI buses and provides the ability to overcome PCI electrical load limits.The addition of the Intel ®i960®core processor brings intelligence to the bridge.The 80960RX,object code compatible with the Intel ®i960®core processor,is capable of sustained execution at the rate of one instruction per clock.The local bus,a 32-bit multiplexed burst bus,is a high-speed interface to system memory and I/O.A full complement of control signals simplifies the connection of the 80960RX to external components.Physical and logical memory attributes are programmed via memory-mapped control registers (MMRs),an extension not found on the Intel ®i960®KX (80960KX),Intel ®i960SX (80960SX)or Intel ®i960®CX (80960CX)processors.Physical and logical configuration registers enable the processor to operate with all combinations of bus width and data object alignment.Figure 1.Product Name Functional

ATUIntel®i960®RX I/O Processor at3.3VoltsFunctional Overview2.1Key Functional Units2.1.1PCI-to-PCI Bridge UnitThe PCI-to-PCI bridge unit(referred to as“bridge”)connects two independent PCI buses.It is fully compliant with the PCI-to-PCI Bridge Architecture Specification,Revision1.0published by the PCI Special Interest Group.It allows certain bus transactions on one PCIbus to be forwarded to the other PCI bus.Dedicated data queues support highperformance bandwidth on the PCI buses.The Product Name supports PCI64-bit DualAddress Cycle(DAC)addressing.The bridge has dedicated PCI configuration space that is accessible through the primaryPCI bus.2.1.2Private PCI Device SupportA key design feature is that the80960RX explicitly supports private PCI devices on thesecondary PCI bus without being detected by PCI configuration software.The bridge andAddress Translation Unit work together to hide private devices from PCI configurationcycles and allow these devices to use a private PCI address space.The AddressTranslation Unit uses normal PCI configuration cycles to configure these devices.2.1.3DMA ControllerThe DMA Controller supports low-latency,high-throughput data transfers between PCIbus agents and80960local memory.Three separate DMA channels accommodate datatransfers:two for primary PCI bus,one for the secondary PCI bus.The DMA Controllersupports chaining and unaligned data transfers.It is programmable only through the Intel®i960®core processor.2.1.4Address Translation UnitThe Address Translation Unit(ATU)allows PCI transactions direct access to the80960RXlocal memory.The80960RX has direct access to both PCI buses.The ATU supportstransactions between PCI address space and80960RX address space.Address translation is controlled through programmable registers accessible from both thePCI interface and the80960core.Dual access to registers allows flexibility in mapping thetwo address spaces.2.1.5Messaging UnitThe Messaging Unit(MU)provides data transfer between the PCI system and the80960RX.It uses interrupts to notify each system when new data arrives.The MU hasfour messaging mechanisms.Each allows a host processor or external PCI device andthe80960RX to communicate through message passing and interrupt generation.Thefour mechanisms are Message Registers,Doorbell Registers,Circular Queues,and IndexRegisters.Functional Overview2.1.6Memory ControllerThe Memory Controller allows direct control of external memory systems,includingDRAM,SRAM,ROM and Flash Memory.It provides a direct connect interface to memorythat typically does not require external logic.It features programmable chip selects,a waitstate generator and byte parity.External memory can be configured as PCI addressablememory or private processor memory.2.1.7I2C Bus Interface UnitThe I2C(Inter-Integrated Circuit)Bus Interface Unit allows the80960core to serve as amaster and slave device residing on the I2C bus.The I2C bus is a serial bus developed byPhilips Semiconductor consisting of a two pin interface.The bus allows the80960RX tointerface to other I2C peripherals and microcontrollers for system management functions.It requires a minimum of hardware for an economical system to relay status and reliabilityinformation on the I/O subsystem to an external device.For more information,see I2CPeripherals for Microcontrollers(Philips Semiconductor)2.1.7.1I/O APIC Bus Interface UnitThe I/O APIC Bus Interface Unit provides an interface to the three-wire AdvancedProgrammable Interrupt Controller(APIC)bus that allows I/O APIC emulation in software.Interrupt messages can be sent on the bus and EOI messages can be received.2.1.7.2Secondary PCI Arbitration UnitThe Secondary PCI Arbitration Unit provides PCI arbitration for the secondary PCI bus.Itincludes a fairness algorithm with programmable priorities and six PCI Request and Grantsignal pairs.This arbitration unit can also be disabled to allow for external arbitration.FunctionalOverview2.2Intel ®i960®Core Features (Intel ®80960JF)The processing power of the 80960RX comes from the 80960JF processor core.The 80960JF is a new,scalar implementation of the 80960Core Architecture.Figure 2shows a block diagram of the 80960JF Core processor.Factors that contribute to the 80960family core performance include:•Single-clock execution of most instructions •Independent Multiply/Divide Unit •Efficient instruction pipeline minimizes pipeline break latency •Register and resource scoreboarding allow overlapped instruction execution •128-bit register bus speeds local register caching •4Kbyte two-way set-associative,integrated instruction cache •2Kbyte direct-mapped,integrated data cache •1Kbyte integrated data RAM delivers zero wait state program data The 80960core operates out of its own 32-bit address space,which is independent of the PCI address space.The local bus memory can be:•Made visible to the PCI address space •Kept private to the 80960core •Allocated as a combination of the two Figure 2.80960JF Core Block Diagram Programmable Bus Control Unit Interrupt Controller Control Address/Instruction Sequencer Physical Region

CacheFunctional Overview2.2.1Burst BusA32-bit high-performance bus controller interfaces the80960RX to external memory andperipherals.The Bus Control Unit fetches instructions and transfers data on the local busat the rate of up to four32-bit words per six clock cycles.The external address/data bus ismultiplexed.Users may configure the80960RX bus controller to match the fundamental memoryorganization of an application.Physical bus width is programmable for up to eight regions.Data caching is programmed through a group of logical memory templates and a defaultsregister.The Bus Control Unit features include:•Multiplexed external bus minimizes pin count•32-,16-and8-bit bus widths simplify I/O interfaces•External ready control for address-to-data,data-to-data and data-to-next-address wait state types•Little endian byte ordering•Unaligned bus accesses performed transparentlyThree-deep load/store queue decouples the bus from the80960coreUpon reset,the80960RX conducts an internal self test.Before executing its firstinstruction,it performs an external bus confidence test by performing a checksum on thefirst words of the Initialization Boot Record.2.2.2Timer UnitThe timer unit(TU)contains two independent32-bit timers that are capable of counting atseveral clock rates and generating interrupts.Each is programmed by use of the TimerUnit registers.These memory-mapped registers are addressable on32-bit boundaries.The timers have a single-shot mode and auto-reload capabilities for continuous operation.Each timer has an independent interrupt request to the80960RX interrupt controller.TheTU can generate a fault when unauthorized writes from user mode are detected.2.2.3Priority Interrupt ControllerLow interrupt latency is critical to many embedded applications.As part of its highly flexibleinterrupt mechanism,the80960RX exploits several techniques to minimize latency:•Interrupt vectors and interrupt handler routines can be reserved on-chip•Register frames for high-priority interrupt handlers can be cached on-chip•The interrupt stack can be placed in cacheable memory spaceFunctional Overview2.2.4Faults and DebuggingThe80960RX employs a comprehensive fault model.The processor responds to faults bymaking implicit calls to a fault handling routine.Specific information collected for eachfault allows the fault handler to diagnose exceptions and recover appropriately.The processor also has built-in debug capabilities.Via software,the80960RX may beconfigured to detect as many as seven different trace event types.Alternatively,mark andfmark instructions can generate trace events explicitly in the instruction stream.Hardwarebreakpoint registers are also available to trap on execution and data addresses.2.2.5On-Chip Cache and Data RAMMemory subsystems often impose substantial wait state penalties.The80960RXintegrates considerable storage resources on-chip to decouple CPU execution from theexternal bus.It also includes a4Kbyte instruction cache,a2Kbyte data cache and1Kbyte data RAM.2.2.6Local Register CacheThe80960RX rapidly allocates and deallocates local register sets during contextswitches.The processor needs to flush a register set to the stack only when it saves morethan seven sets to its local register cache.2.2.7Test FeaturesThe80960RX incorporates numerous features that enhance the user ability to test boththe processor and the system to which it is attached.These features include ONCE(On-Circuit Emulation)mode and Boundary Scan(JTAG).The80960RX provides testability features compatible with IEEE Standard Test AccessPort and Boundary Scan Architecture(IEEE Std.1149.1).One of the boundary scan instructions,HIGHZ,forces the processor to float all its outputpins(ONCE mode).ONCE mode can also be initiated at reset without using the boundaryscan mechanism.ONCE mode is useful for board-level testing.This feature allows a mounted80960RX toelectrically“remove”itself from a circuit board.This mode allows system-level testingwhere a remote tester can exercise the processor system.The test logic does not interfere with component or system behavior and ensures thatcomponents function correctly,and also the connections between various componentsare correct.The JTAG Boundary Scan feature is an alternative to conventional“bed-of-nails”testing.Itcan examine connections that might otherwise be inaccessible to a test system.Functional Overview2.2.8Memory-Mapped Control RegistersThe80960RX is compliant with80960family architecture and has the added advantage ofmemory-mapped,internal control registers not found on the80960KX,80960SX or80960CX processors.This feature provides software an interface to easily read andmodify internal control registers.Each memory-mapped,32-bit register is accessed via regular memory-formatinstructions.The processor ensures that these accesses do not generate external buscycles.2.2.9Instructions,Data Types and Memory Addressing ModesAs with all80960family processors,the80960RX instruction set supports severaldifferent data types and formats:•Bit•Bit fields•Integer(8-,16-,32-,64-bit)•Ordinal(8-,16-,32-,64-bit unsigned integers)•Triple word(96bits)•Quad word(128bits)The80960RX provides a full set of addressing modes for C and assembly:•Two Absolute modes•Five Register Indirect modes•Index with displacement mode•IP with displacement modeTable2shows the available instructions.FunctionalOverviewTable2.80960RX Instruction SetData Movement Arithmetic

地址锁存与译码电路完成对A、B、C 3个地址位进行锁存和译码,其译码输出用于通道选择,其转换结果通过三态输出锁存器存放、输出,因此可以直接与系统数据总线相连,表9-1为通道选择表。

表9-1 通道选择表2.信号引脚ADC0809芯片为28引脚为双列直插式封装,其引脚排列见图9.8。

对ADC0809主要信号引脚的功能说明如下:IN7~IN0——模拟量输入通道ALE——地址锁存允许信号。

对应ALE上跳沿,A、B、C地址状态送入地址锁存器中。

START——转换启动信号。

START上升沿时,复位ADC0809;START下降沿时启动芯片,开始进行A/D转换;在A/D转换期间,START应保持低电平。

本信号有时简写为ST.A、B、C——地址线。

通道端口选择线,A为低地址,C为高地址,引脚图中为ADDA,ADDB和ADDC。

其地址状态与通道对应关系见表9-1。

CLK——时钟信号。

ADC0809的内部没有时钟电路,所需时钟信号由外界提供,因此有时钟信号引脚。

通常使用频率为500KHz的时钟信号EOC——转换结束信号。

EOC=0,正在进行转换;EOC=1,转换结束。

使用中该状态信号即可作为查询的状态标志,又可作为中断请求信号使用。

D7~D0——数据输出线。

11.2.4 典型的集成ADC芯片为了满足多种需要,目前国内外各半导体器件生产厂家设计并生产出了多种多样的ADC芯片。

仅美国AD公司的ADC产品就有几十个系列、近百种型号之多。

从性能上讲,它们有的精度高、速度快,有的则价格低廉。

从功能上讲,有的不仅具有A/D转换的基本功能,还包括内部放大器和三态输出锁存器;有的甚至还包括多路开关、采样保持器等,已发展为一个单片的小型数据采集系统。

尽管ADC芯片的品种、型号很多,其内部功能强弱、转换速度快慢、转换精度高低有很大差别,但从用户最关心的外特性看,无论哪种芯片,都必不可少地要包括以下四种基本信号引脚端:模拟信号输入端(单极性或双极性);数字量输出端(并行或串行);转换启动信号输入端;转换结束信号输出端。

除此之外,各种不同型号的芯片可能还会有一些其他各不相同的控制信号端。

选用ADC芯片时,除了必须考虑各种技术要求外,通常还需了解芯片以下两方面的特性。

(1)数字输出的方式是否有可控三态输出。

有可控三态输出的ADC芯片允许输出线与微机系统的数据总线直接相连,并在转换结束后利用读数信号RD选通三态门,将转换结果送上总线。

没有可控三态输出(包括内部根本没有输出三态门和虽有三态门、但外部不可控两种情况)的ADC芯片则不允许数据输出线与系统的数据总线直接相连,而必须通过I/O接口与MPU交换信息。

(2)启动转换的控制方式是脉冲控制式还是电平控制式。

对脉冲启动转换的ADC芯片,只要在其启动转换引脚上施加一个宽度符合芯片要求的脉冲信号,就能启动转换并自动完成。

一般能和MPU配套使用的芯片,MPU的I/O写脉冲都能满足ADC芯片对启动脉冲的要求。

对电平启动转换的ADC芯片,在转换过程中启动信号必须保持规定的电平不变,否则,如中途撤消规定的电平,就会停止转换而可能得到错误的结果。

为此,必须用D 触发器或可编程并行I/O 接口芯片的某一位来锁存这个电平,或用单稳等电路来对启动信号进行定时变换。
