SN54LS123中文资料
RETRIGGERABLE MONOSTABLE MULTIVIBRATORSThese dc triggered multivibrators feature pulse width control by three meth-ods. The basic pulse width is programmed by selection of external resistance and capacitance values. The LS122 has an internal timing resistor that allows the circuits to be used with only an external capacitor. Once triggered, the ba-sic pulse width may be extended by retriggering the gated low-level-active (A)or high-level-active (B) inputs, or be reduced by use of the overriding clear.•Overriding Clear Terminates Output Pulse•Compensated for V CC and T emperature Variations•DC Triggered from Active-High or Active-Low Gated Logic Inputs •Retriggerable for Very Long Output Pulses, up to 100% Duty Cycle •Internal Timing Resistors on LS122SN54/74LS122 (TOP VIEW)(SEE NOTES 1 THRU 4)SN54/74LS123 (TOP VIEW)(SEE NOTES 1 THRU 4)NOTES:1.An external timing capacitor may be connected between C ext and R ext /C ext (positive).2.To use the internal timing resistor of the LS122, connect R int to V CC .3.For improved pulse width accuracy connect an external resistor between R ext /C ext and V CC with R int open-circuited.4.To obtain variable pulse widths, connect an external variable resistance between R int /C ext and V CC .R ext/CR ext/C ext 11ĂRext/2CLRC extNC Ċ NO INTERNAL CONNECTION.。

1、 关闭MCU全局中断和/INT中断； 2、 MCU通过串口读RIF寄存器，清IF和RIF寄存器，将IRQ恢复到高电平； 3、 MCU通过判断RIF的中断标志来判断RN8209的中断源，转而执行相应的中断
处理程序；在此过程中，RN8209若发生新的中断事件，IF相关标志置位， IRQ也会由高变低，触发MCU的/INT中断标志置位，记录了此事件；
CS 上升沿之间的时间间隔 t2 要大于等于半个 SCLK 周期。
注意：有写保护功能的寄存器在写操作之前要先写入写使能命令。
4. 4. 4、SPI 读操作
MCU 在 CS 有效后，先通过 SPI 写入命令字节（8bit，包含寄存器地址）,RN8209收 到读命令后，在 SCLK 的上升沿将数据按位从 SDO 引脚输出。
3. 在最后一个比特移出 SDO 后，CS 由低至高时将 RIF 寄存器的内容和 IF 同步。
除了读 RIF 寄存器操作，其他情况下 IF 和 RIF 都保持一致。为了在 SPI 读中断标志 过程中不丢失中断，在中断处理程序中推荐用户使用 RIF 寄存器。

R8C/24 Group, R8C/25 GroupSINGLE-CHIP 16-BIT CMOS MCU1.OverviewThese MCUs are fabricated using a high-performance silicon gate CMOS process, embedding the R8C/Tiny Series CPU core, and are packaged in a 52-pin molded-plastic LQFP or a 64-pin molded-plastic FLGA. It implements sophisticated instructions for a high level of instruction efficiency. With 1 Mbyte of address space, they are capable of executing instructions at high speed.Furthermore, the R8C/25 Group has on-chip data flash (1 KB x 2 blocks).The difference between the R8C/24 Group and R8C/25 Group is only the presence or absence of data flash. Their peripheral functions are the same.1.1ApplicationsElectronic household appliances, office equipment, audio equipment, consumer products, etc.REJ03B0117-0300Rev.3.00Feb 29, 20081.2Performance OverviewTable 1.1 outlines the Functions and Specifications for R8C/24 Group and Table 1.2 outlines the Functions and Specifications for R8C/25 Group.NOTES:1.I 2C bus is a trademark of Koninklijke Philips Electronics N.

The CPU contains 13 registers. R0, R1, R2, R3, A0, A1, and FB configure a register bank. There are two sets of register bank.2.1Data Registers (R0, R1, R2, and R3)R0 is a 16-bit register for transfer, arithmetic, and logic operations. The same applies to R1 to R3. R0 can be split into high-order bits (R0H) and low-order bits (R0L) to be used separately as 8-bit data registers. R1H and R1L are analogous to R0H and R0L. R2 can be combined with R0 and used as a 32-bit data register (R2R0). R3R1 is analogous to R2R0.2.2Address Registers (A0 and A1)A0 is a 16-bit register for address register indirect addressing and address register relative addressing. It is also used for transfer, arithmetic, and logic operations. A1 is analogous to A0. A1 can be combined with A0 and as a 32-bit address register (A1A0).2.3Frame Base Register (FB)FB is a 16-bit register for FB relative addressing.2.4Interrupt Table Register (INTB)INTB is a 20-bit register that indicates the start address of an interrupt vector table.2.5Program Counter (PC)PC is 20 bits wide and indicates the address of the next instruction to be executed.2.6User Stack Pointer (USP) and Interrupt Stack Pointer (ISP)The stack pointers (SP), USP, and ISP, are each 16 bits wide. The U flag of FLG is used to switch betweenUSP and ISP.2.7Static Base Register (SB)SB is a 16-bit register for SB relative addressing.2.8Flag Register (FLG)FLG is an 11-bit register indicating the CPU state.2.8.1Carry Flag (C)The C flag retains carry, borrow, or shift-out bits that have been generated by the arithmetic and logic unit.2.8.2Debug Flag (D)The D flag is for debugging only. Set it to 0.2.8.3Zero Flag (Z)The Z flag is set to 1 when an arithmetic operation results in 0; otherwise to 0.2.8.4Sign Flag (S)The S flag is set to 1 when an arithmetic operation results in a negative value; otherwise to 0.2.8.5Register Bank Select Flag (B)Register bank 0 is selected when the B flag is 0. Register bank 1 is selected when this flag is set to 1.2.8.6Overflow Flag (O)The O flag is set to 1 when an operation results in an overflow; otherwise to 0.2.8.7Interrupt Enable Flag (I)The I flag enables maskable interrupts.Interrupt are disabled when the I flag is set to 0, and are enabled when the I flag is set to 1. The I flag is set to 0 when an interrupt request is acknowledged.2.8.8Stack Pointer Select Flag (U)ISP is selected when the U flag is set to 0; USP is selected when the U flag is set to 1.The U flag is set to 0 when a hardware interrupt request is acknowledged or the INT instruction of software interrupt numbers 0 to 31 is executed.2.8.9Processor Interrupt Priority Level (IPL)IPL is 3 bits wide and assigns processor interrupt priority levels from level 0 to level 7.If a requested interrupt has higher priority than IPL, the interrupt is enabled.2.8.10Reserved BitIf necessary, set to 0. When read, the content is undefined.3.Memory3.1R8C/24 GroupFigure 3.1 is a Memory Map of R8C/24 Group. The R8C/24 group has 1 Mbyte of address space from addresses 00000h to FFFFFh.The internal ROM is allocated lower addresses, beginning with address 0FFFFh. For example, a 48-Kbyte internal ROM area is allocated addresses 04000h to 0FFFFh.The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. They store the starting address of each interrupt routine.The internal RAM is allocated higher addresses, beginning with address 00400h. For example, a 2-Kbyte internal RAM area is allocated addresses 00400h to 00BFFh. The internal RAM is used not only for storing data but also for calling subroutines and as stacks when interrupt requests are acknowledged.Special function registers (SFRs) are allocated addresses 00000h to 002FFh. The peripheral function control registers are allocated here. All addresses within the SFR, which have nothing allocated are reserved for future use and cannot be accessed by users.3.2R8C/25 GroupFigure 3.2 is a Memory Map of R8C/25 Group.

Input/Output Voltage With –200-V Machine Model (A115-A)3.3-V V CC )The SN54LVCH245A octal bus transceiver is designed for 2.7-V to 3.6-V V CC operation,and the SN74LVCH245A octal bus transceiver is designed for 1.65-V to 3.6-V V CC operation.Inputs can be driven from either 3.3-V or 5-V devices.This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.These devices are designed for asynchronous communication between data buses.These devices transmit data from the A bus to the B bus or from the B bus to the A bus,depending on the logic level at the direction-control (DIR)input.The output-enable (OE)input can be used to disable the device so the buses are effectively isolated.These devices are fully specified for partial-power-down applications using I off .The I off circuitry disables the outputs,preventing damaging current backflow through the devices when they are powered down.To ensure the high-impedance state during power up or power down,OE should be tied to V CC through a pullup resistor;the minimum value of the resistor is determined by the current-sinking capability of the driver.Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic e of pullup or pulldown resistors with the bus-hold circuitry is not recommended.The bus-hold circuitry is part of the input circuit and is not disabled by OE or DIR.Please be aware that an important notice concerning availability,standard warranty,and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.GQN OR ZQN PACKAGE(TOP VIEW)1234A B C D ESN54LVCH245A,SN74LVCH245A OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTSSCES008O–JULY 1995–REVISED

单片机技术应用
单片机如下的发展趋势：低功耗CMOS化、微型单片化、主流与多品种共存、功能更强大。
8051芯片内部共有256个字节单、RAM存储器和4KB字节单元的ROM存储器、其中RAM 存储器又分为高128字节单元和低128个字节单元。
而高128个存储单元中的一部分被特殊功能寄存器占用，其余单元用户不能使用。
通常所说的内RAM ，就是指低128个字节单元。
而rom存储器主要用于存放程序、原始数据和表格内容，成为程序存储器，也成为片内ROM。
8051芯片内部有一个高增益反向放大器，用于构成震荡电路。
反相放大器的输入端和输出端用于外接石英晶体和微调电容构成震荡电路。
始终周期：时钟周期又称为震荡周期。
状态周期：一个状态周期等于两个时钟周期。
机器周期：1个机器周期等于6个状态周期（12震荡周期）指令周期：指令周期是指执行一条指令所需要的时间，一个指令周期又1~4个机器周期组成。
单片机每一个指令的执行都可以包括取指和执行两个过程。
CPU执行指令时，由程序储存器中读取指令代码送入指令寄存器，经译码后由定时与控制电路发出相应的控制信号，完成指令功能。
MCS-51单片机共有4个8位的准双向并行I/O端口，即P0、P1、P2、P3，这些端口既可以作为一般的输入输出口使用，也还可以用作他用。
8051单片机共有5个中断源，即2个外部中断源、两个定时器/计数器、1个串行口中断源。
全部中断源可以设定为高低2个优先级，用来满足控制应用的需要。
RST是复位信号输入端，高电平有效。
系统通电后在此引脚上至少要保持2个机器周期（24个时钟周期）以上的高电平才能有效地完成复位操作。
PSEN：该引脚的功能主要用于片外ROM读选通信号输出端。
EA为片内、外ROM选择控制引脚，当=1（接高电平）时，表示方位片内ROM；=0（接地）时，表示访问片外ROM。
MCS-51单片机低12B的数据存储器RAM，按其功能的不同，可划分为三个区域。
工作寄存器区分为4组，一次被称为第0~3组，每组都可以用R0~R7作为单元编号。
