The two large on-chip buffers accommodate data flow from two different buses. The USB bulk-type data is adopted for maximum data transfer. Automatic handshake is supported at the Serial port. With these, a much higher baud rate can be achieved compared to the legacy UART controller.This device is also compliant with USB power management and remote wakeup scheme. Only minimum power is consumed from the host during Suspend. By integrating all the function in a SOIC-28 package, this chip is suitable for cable embedding. Users just simply hook the cable into PC or hub’s USB port, and then they can connect to any RS-232 devices.Pin DescriptionTable 1.

After reset, the first two bytes of EEPROM are checked. If the value is 067Bh, the EEPROM is valid and the contents of the EEPROM are loaded as the chip’s default parameters. Otherwise, the chip’s default setting is used. The content of EEPROM is shown in Table 4 below.The Device Configuration Register is used to control some vendor-specific functions. The meaning of each bit in Device Configuration Register is shown in Table 5. Reserved and unused pins always set to the default value.Table 4. EEPROM ContentBytes Name Description1:0 EECHK When the EEPROM is programmed, these two bytes is configured as 067B.After reset, they will be checked for the value.

The FT232RL is a USB to serial UART interface with optional clock generator output, and the FTDIChip-ID™ security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. The FT232RL adds two new functions compared with its predecessors, effectively making it a “3-in-1” chip for some application areas. The internally generated clock (6MHz, 12MHz, 24MHz, and 48MHz) can be brought out of the device and used to drive a microcontroller or external logic. A unique number (the FTDIChip-ID™) is burnt into the device during manufacture and is readable over USB, thus forming the basis of a security dongle which can be used to protect customer application software from being copied. (Safe-Guard-IT). The UM232R is supplied on a PCB which is designed to plug into a standard 0.6” wide 24 pin DIP socket. All components used, including the FT232RL are Pb-free (RoHS compliant).

For further details, consult the FT232R datasheet, which is available from.Integrated Clock Circuit –Previous generations of FTDI‟s USB UART devices required an external crystalor ceramic resonator. The clock circuit has now been integrated onto the device meaning that no crystal orceramic resonator is required. However, if preferred, an external 12MHz crystal can be used as the clocksource. Note that the UM232R does not provide access to these pins on the FT232R device. Integrated EEPROM –Previous generations of FTDI‟s USB UART devices required an external EEPROM ifthe device were to use USB Vendor ID (VID), Product ID (PID), serial number and product descriptionstrings other than the default values in the device itself. This external EEPROM has now been integratedonto the FT232R chip meaning that all designs have the option to change the product description strings. Auser area of the internal EEPROM is available for storing additional data. The internal EEPROM isprogrammable in circuit, over USB without any additional voltage requirement. Preprogrammed EEPROM –The FT232R is supplied with its internal EEPROM pre-programmed with aserial number which is unique to each individual device. This, in most cases, will remove the need toprogram the device EEPROM.Integrated USB Resistors –Previous generations of FTDI‟s USB UART devices required two externalseries resistors on the USBDP and USBDM lines, and a 1.5 kΩ pull up resistor on USBDP. These threeresistors have now been integrated onto the device.Integrated AVCC Filtering –Previous generations of FTDI‟s USB UART devices had a separate AVCC pin –the supply to the internal PLL. This pin required an external R-C filter. The separate AVCC pin is nowconnected internally to VCC, and the filter has now been integrated onto the chip.Less External Components –Integration of the crystal, EEPROM, USB resistors, and AVCC filter willsubstantially reduce the bill of materials cost for USB interface designs using the FT232R compared to itsFT232BM predecessor.Configurable CBUS I/O Pin Options –There are now 5 configurable Control Bus (CBUS) lines. Optionsare TXDEN – transmit enable for RS485 designs, PWREN# - Power control for high power, bus powereddesigns, TXLED# - for pulsing an LED upon transmission of data, RXLED# - for pulsing an LED uponreceiving data, TX&RXLED# - which will pulse an LED upon transmission OR reception of data, SLEEP# -indicates that the device going into USB suspend mode, CLK48 / CLK24 / CLK12 / CLK6 – 48MHz,24MHz,12MHz, and 6MHz clock output signal options. There is also the option to bring out bit bang moderead and write strobes (see below). The CBUS lines can be configured with any one of these output optionsby setting bits in the internal EEPROM. The device is supplied with the most commonly used pin definitionspre-programmed – see Section 9 for details.Enhanced Asynchronous Bit Bang Mode with RD# and WR# Strobes –The FT232R supports FTDI‟sBM chip bit bang mode. In bit bang mode, the eight UART lines can be switched from the regular interfacemode to an 8-bit general purpose I/O port. Data packets can be sent to the device and they will besequentially sent to the interface at a rate controlled by an internal timer (equivalent to the baud rateprescaler). With the FT232R device this mode has been enhanced so that the internal RD# and WR#strobes are now brought out of the device which can be used to allow external logic to be clocked byaccesses to the bit bang I/O bus. This option will be described more fully in a separate application note. Synchronous Bit Bang Mode –Synchronous bit bang mode differs from asynchronous bit bang mode inthat the interface pins are only read when the device is written to. Thus making it easier for the controllingprogram to measure the response to an output stimulus as the data returned is synchronous to the outputdata. The feature was previously seen in FTDI‟s FT2232C device. This option will be described more fully ina separate application note.CBUS Bit Bang Mode –This mode allows four of the CBUS pins to be individually configured as GPIO pins,similar to Asynchronous bit bang mode. It is possible to use this mode while the UART interface is beingused, thus providing up to four general purpose I/O pins which are available during normal operation. Anapplication note describing this feature is available separately from .Lower Supply Voltage –Previous generations of the chip required 5V supply on the VCC pin. The FT232Rwill work with a VCC supply in the range 4.0V to 5.25V. Bus powered designs would still take their supplyfrom the 5V on the USB bus.Integrated Level Converter on UART Interface and Control Signals – VCCIO pin supply can be from1.8V to 5V. Connecting the VCCIO pin to 1.8V,2.8V, or3.3V allows the device to directly interface to 1.8V,2.8V or3.3V and other logic families without the need for external level converter I.C. devices.5V / 3.3V / 2.8V / 1.8V Logic Interface –The FT232R provides true CMOS Drive Outputs and TTL levelInputs.Integrated Power-On-Reset (POR) Circuit- The device incorporates an internal POR function. A RESET#pin is available in order to allow external logic to reset the FT232R where required. However, for manyapplications the RESET# pin can be left unconnected, or pulled up to VCCIO.Lower Operating and Suspend Current –The device operating supply current has been further reducedto 15mA, and the suspend current has been reduced to around 70μA. This allows greater margin forperipheral designs to meet the USB suspend current limit of 500μA.Low USB Bandwidth Consumption –The operation of the USB interface to the FT232R has beendesigned to use as little as possible of the total USB bandwidth available from the USB host controller.High Output Drive Option –The UART interface and CBUS I/O pins can be made to drive out at threetimes the standard signal drive level thus allowing multiple devices to be driven, or devices that requiregreater signal drive strength to be interfaced to the FT232R. This option is enabled in the internal EEPROM. Power Management Control for USB Bus Powered, High Current Designs –The PWREN# signal canbe used to directly drive a transistor or P-Channel MOSFET in applications where power switching ofexternal circuitry is required. An option in the internal EEPROM makes the device gently pull down on itsUART interface lines when the power is shut off (PWREN# is high). In this mode any residual voltage onexternal circuitry is bled to GND when power is removed, thus ensuring that external circuitry controlled byPWREN# resets reliably when power is restored.UART Pin Signal Inversion –The sense of each of the eight UART signals can be individually inverted bysetting options in the internal EEPROM. Thus, CTS# (active low) can be changed to CTS (active high), orTXD can be changed to TXD#.FTDIChip-ID™ - Each FT232R is assigned a unique number which is burnt into the device at manufacture.This ID number cannot be reprogrammed by product manufacturers or end-users. This allows the possibilityof using FT232R based dongles for software licensing. Further to this, a renewable license scheme can be implemented based on the FTDIChip-ID™ number when encrypted with other information. This encryptednumber can be stored in the user area of the FT232R internal EEPROM, and can be decrypted, thencompared with the protected FTDIChip-ID™ to verify that a license is valid. Web based applications can beused to maintain product licensing this way. An application note describing this feature is availableseparately from .Improved EMI Performance –The reduced operating current and improved on-chip VCC decouplingsignificantly improves the ease of PCB design requirements in order to meet FCC, CE and other EMI related specifications.Programmable Receive Buffer Timeout –The receive buffer timeout is used to flush remaining datafrom the receive buffer. This time defaults to 16ms, but is programmable over USB in 1ms increments from1ms to 255ms, thus allowing the device to be optimised for protocols that require fast response times fromshort data packets.Baud Rates –The FT232R supports all standard baud rates and non-standard baud rates from 300 Baudup to 3 Megabaud. Achievable non-standard baud rates are calculated as follows –Baud Rate = 3000000 /(n + x) where …n‟ can be any integer between 2 and 16,384 (= 214) and …x’ can be a sub-integer of thevalue 0, 0.125, 0.25, 0.375, 0.5, 0.625, 0.75, or 0.875. When n = 1, x = 0, i.e. baud rate divisors withvalues between 1 and 2 are not possible. This gives achievable baud rates in the range 183.1 baud to3,000,000 baud. When a non-standard baud rate is required simply pass the required baud rate value tothe driver as normal, and the FTDI driver will calculate the required divisor, and set the baud rate. SeeFTDI application note AN232B-05 for more details.Extended Operating Temperature Range – The FT232R operates over an extended temperature rangeof -40º to +85º C thus allowing the device to be used in automotive and industrial applications.Package Options – The FT232R is available in two packages – a compact 28 pin SSOP ( FT232RL) and anultra-compact 5mm x 5mm pinless QFN-32 package ( FT232RQ). Both packages are lead ( Pb ) free, anduse a …green‟ compound. Both packages are fully compliant with European Union directive 2002/95/EC.4UM232R Pin Out and Signal Descriptions 4.1 UM232R Pin OutFigure 4.1 Module Pin Out and Jumper Locations4.2Signal Descriptions* When used in Suspend, these pins are pulled to VCCIO via internal 200k Ω resistors. These pins can be programmed to gently pull low during USB suspend (PWREN # = “1”) by setting an option in the internal EEPROM.4.3 Jumper Configuration Options分销商库存信息: FTDIUM232R。

MAX232中文资料及应用

MAX232中文资料及应用一.max232资料简介该产品是由德州仪器公司（TI）推出的一款兼容RS232标准的芯片。

由于电脑串口rs232电平是-10v +10v，而一般的单片机应用系统的信号电压是ttl电平0 +5v,max232就是用来进行电平转换的,该器件包含2驱动器、2接收器和一个电压发生器电路提供TIA/EIA-232-F电平。

该器件符合TIA/EIA-232-F标准，每一个接收器将TIA/EIA-232-F电平转换成5-V TTL/CMOS电平。

每一个发送器将TTL/CMOS电平转换成TIA/EIA-232-F电平。

主要特点1、单5V电源工作2、 LinBiCMOSTM工艺技术3、两个驱动器及两个接收器4、±30V输入电平5、低电源电流：典型值是8mA6、符合甚至优于ANSI标准 EIA/TIA-232-E及ITU推荐标准V.287、ESD保护大于MIL-STD-883（方法3015）标准的2000V下图为MX232双串口的连接图，可以分别接单片机的串行通信口或者实验板的其它串行通信接口：三.max232应用电路，注意电容接法。

232是电荷泵芯片，可以完成两路TTL/RS-232电平的转换，它的的9、10、11、12引脚是TTL电平端，用来连接单片机的。

制作at89s51单片机器编程器的电路图MAX232获得正负电源的另一种方法在单片机控制系统中，我们时常要用到数/模（D/A）或者模/数(A/D)变换以及其它的模拟接口电路，这里面要经常用到正负电源，例如： 9V,-9V; 12V,-12V.这些电源仅仅作为数字和模拟控制转换接口部件的小功率电源。

在控制板上，我们有的只是5V电源，可又有很多方法获得非5V电源。

1.外接；2.DC-DC变换......在这里我介绍一块大家常用的芯片：MAX232. MAX232是TTL--RS232电平转换的典型芯片，按照芯片的推荐电路，取振荡电容为uF的时候，若输入为5V,输出可以达到-14V左右，输入为0V ,输出可以达到14V,在扇出电流为20mA的时候，处处电压可以稳定在 12V和-12V.因此，在功耗不是很大的情况下，可以将MAX232的输出信号经稳压块后作电源使用。

MAX232原理及应用

RS232 (DB9)引脚定义1 ：DCD :载波检测。

主要用于Modem通知计算机其处于在线状态，即Modem检测到拨号音，处于在线状态。

2 ：RXD:此引脚用于接收外部设备送来的数据；在你使用Modem时，你会发现RXD指示灯在闪烁，说明RXD引脚上有数据进入。

3 ：TXD:此引脚将计算机的数据发送给外部设备；在你使用Modem时，你会发现TXD指示灯在闪烁，说明计算机正在通过TXD引脚发送数据。

4 ：DTR:数据终端就绪；当此引脚高电平时，通知Modem可以进行数据传输，计算机已经准备好。

5 ：GND:信号地；此位不做过多解释。

6 ：DSR:数据设备就绪；此引脚高电平时，通知计算机Modem已经准备好，可以进行数据通讯了。

7 ：RTS:请求发送；此脚由计算机来控制，用以通知Modem马上传送数据至计算机；否则，Modem将收到的数据暂时放入缓冲区中。

8 ：CTS: 清除发送；此脚由Modem控制，用以通知计算机将欲传的数据送至Modem。

9 ：RI : Modem通知计算机有呼叫进来，是否接听呼叫由计算机决定MAX232原理MAX232芯片是专门为电脑的RS-232标准串口设计的接口电路,使用+5v 单电源供电。

内部结构基本可分三个部分：第一部分是电荷泵电路。

由1、2、3、4、5、6脚和4只电容构成。

功能是产生+12v和-12v两个电源，提供给RS-232串口电平的需要。

第二部分是数据转换通道。

由7、8、9、10、11、12、13、14脚构成两个数据通道。

其中13脚（R1IN）、12脚（R1OUT）、11脚（T1IN）、14脚（T1OUT）为第一数据通道。

8脚（R2IN）、9脚（R2OUT）、10脚（T2IN）、7脚（T2OUT）为第二数据通道。

TTL/CMOS数据从T1IN、T2IN输入转换成RS-232数据从T1OUT、T2OUT送到电脑DP9插头；DP9插头的RS-232数据从R1IN、R2IN输入转换成TTL/CMOS数据后从R1OUT、R2OUT输出。
