13、scriptionThe STC89C52 is a low-power， high-performance CMOS 8-bit microcontroller with 8Kbytes of in-system programmable Flash memory. The device is manufactured using Atmels high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 instruction set and pinout. The

14、 on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with in-system programmable Flash on a monolithic chip， the Atmel STC89C52 is a powerful microcontroller which provides a highly-flexible and c

15、ost-effective solution to many embedded control applications.The STC89C52 provides the following standard features: 8K bytes of Flash， 256 bytes of RAM， 32 I/O lines， Watchdog timer， two data pointers， three 16-bit timer/counters， a six-vector two-level interrupt architecture， a full duplex serial p

16、ort， on-chip oscillator， and clock circuitry. In addition， the STC89C52 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM， timer/counters， serial port， and interrupt system to

17、 continue functioning. The Power-down mode saves the RAM contents but freezes the oscillator， disabling all other chip functions until the next interrupt or hardware reset.VCC Supply voltage.GND Ground.Port 0 Port 0 is an 8-bit open drain bidirectional I/O port. As an output port， each pin can sink

18、eight TTL inputs. When 1sare written to port 0 pins， the pins can be used as highimpe dance inputs. Port 0 can also be configured to be the multiplexed loworder address/data bus during accesses to external program and data memory. In this mode， P0 has internal pullups. Port 0 also receives the code

19、bytes during Flash programming and outputs the code bytes during program verification. External pullups are required during program verification.Port 1 Port 1 is an 8-bit bidirectional I/O port with internal pullups. The Port 1 output buffers can sink/source four TTL inputs. When 1s are written to P

20、ort 1 pins， they are pulled high by the internal pullups and can be used as inputs. As inputs， Port 1 pins that are externally being pulled low will source current (IIL) because of the internal pullups. In addition， P1.0 and P1.1 can be configured to be the timer/counter 2 external count input (P1.0

21、/T2) and the timer/counter 2 trigger input (P1.1/T2EX)， respectively， Port 1 also receives the low-order address bytes during Flash programming and verificationPort 2 Port 2 is an 8-bit bidirectional I/O port with internal pullups. The Port 2 output buffers can sink/source four TTL inputs. When 1s a

22、re written to Port 2 pins， they are pulled high by the internal pullups and can be used as inputs. Port 2 emits the high-order address byte during fetches from external program memory and during accesses to external data memory that use 16-bit addresses (MOVX DPTR). In this application， Port 2 uses

23、strong internal pull-ups when emitting 1s. During accesses to external data memory that use 8-bit addresses (MOVX RI)， Port 2 emits the contents of the P2 Special Function Register. Port 2 also receives the high-order address bits and some control signals during Flash programming and verification.Po

24、rt 3 Port 3 is an 8-bit bidirectional I/O port with internal pullups. The Port 3 output buffers can sink/source four TTL inputs. When 1s are written to Port 3 pins， they are pulled high by the internal pullups and can be used as inputs. As inputs， Port 3 pins that are externally being pulled low wil

25、l source current (IIL) because of the pullups. Port 3 also serves the functions of various special features of the STC89C52， as shown in the following table. Port 3 also receives some control signals for Flash programming and verification.RST Reset input. A high on this pin for two machine cycles wh

26、ile the oscillator is running resets the device. This pin drives High for 96 oscillator periods after the Watchdog times out. The DISRTO bit in SFR AUXR (address 8EH) can be used to disable this feature. In the default state of bit DISRTO， the RESET HIGH out feature is enabled.ALE/PROG Address Latch

27、 Enable (ALE) is an output pulse for latching the low byte of the address during accesses to external memory. This pin is also the program pulse input (PROG) during Flash programming. In normal operation， ALE is emitted at a constant rate of 1/6 the oscillator frequency and may be used for external

28、timing or clocking purposes.If desired， ALE operation can be disabled by setting bit 0 of SFR location 8EH. With the bit set， ALE is active only during a MOVX or MOVC instruction. Otherwise， the pin is weakly pulled high. Setting the ALE-disable bit has no effect if the microcontroller is in externa

29、l execution mode.PSEN Program Store Enable (PSEN) is the read strobe to external program memory. When the STC89C52 is executing code from external program memory， PSEN is activated twice each machine cycle， except that two PSEN activations are skipped during each access to external data memory.EA/VP

30、P External Access Enable. EA must be strapped to GND in order to enable the device to fetch code from external program memory locations starting at 0000H up to FFFFH. Note， however， that if lock bit 1 is programmed， EA will be internally latched on reset. EA should be strapped to VCC for internal pr

31、ogram executions. This pin also receives the 12-volt programming enable voltage (VPP) during Flash programming.XTAL1 Input to the inverting oscillator amplifier and input to the internal clock operating circuit.XTAL2 Output from the inverting oscillator amplifier.译文：STC89C52 数据手册功能特性描述STC89C52是一种低功耗

32、、高性能CMOS8位微控制器，具有8K在系统可编程Flash 存储器。使用高密度非易失性存储器技术制造，与工业80C51产品指令和引脚完全兼容。片上Flash允许程序存储器在系统可编程，亦适于常规编程器。在单芯片上，拥有灵巧的8 位CPU 和在系统可编程Flash，使得STC89C52为众多嵌入式控制应用系统提供高灵活、超有效的解决方案。STC89C52具有以下标准功能； 8k字节Flash，256字节RAM，32 位I/O 口线，看门狗定时器，2个数据指针，三个16 位定时器/计数器，一个6向量2级中断结构，全双工串行口，片内晶振及时钟电路。另外，STC89C52 可降至0Hz 静态逻辑操作

33、，支持2种软件可选择节电模式。空闲模式下，CPU停止工作，允许RAM、定时器/计数器、串口、中断继续工作。掉电保护方式下，RAM内容被保存，振荡器被冻结，单片机一切工作停止，直到下一个中断或硬件复位为止。VCC : 电源GND: 地P0 口：P0口是一个8位漏极开路的双向I/O口。作为输出口，每位能驱动8个TTL逻辑电平。对P0端口写“1”时，引脚用作高阻抗输入。当访问外部程序和数据存储器时，P0口也被作为低8位地址/数据复用。在这种模式下，P0具有内部上拉电阻。在flash编程时，P0口也用来接收指令字节；在程序校验时，输出指令字节。程序校验时，需要外部上拉电阻。P1 口：P1口是一个具有内

34、部上拉电阻的8 位双向I/O 口，p1 输出缓冲器能驱动4个TTL 逻辑电平。对P1 端口写“1”时，内部上拉电阻把端口拉高，此时可以作为输入口使用。作为输入使用时，被外部拉低的引脚由于内部电阻的原因，将输出电流（IIL）。此外，P1.0和P1.2分别作定时器/计数器2的外部计数输入（P1.0/T2）和时器/计数器2的触发输入（P1.1/T2EX），在flash编程和校验时，P1口接收低8位地址字节。P2 口：P2口是一个具有内部上拉电阻的8 位双向I/O 口，P2 输出缓冲器能驱动4个TTL 逻辑电平。对P2 端口写“1”时，内部上拉电阻把端口拉高，此时可以作为输入口使用。作为输入使用时，被

35、外部拉低的引脚由于内部电阻的原因，将输出电流（IIL）。在访问外部程序存储器或用16位地址读取外部数据存储器（例如执行MOVX DPTR）时，P2 口送出高八位地址。在这种应用中，P2 口使用很强的内部上拉发送1。在使用8位地址（如MOVX RI）访问外部数据存储器时，P2口输出P2锁存器的内容。在flash编程和校验时，P2口也接收高8位地址字节和一些控制信号。P3 口：P3 口是一个具有内部上拉电阻的8 位双向I/O 口，P2 输出缓冲器能驱动4个TTL 逻辑电平。对P3 端口写“1”时，内部上拉电阻把端口拉高，此时可以作为输入口使用。作为输入使用时，被外部拉低的引脚由于内部电阻的原因，将

36、输出电流（IIL）。P3口亦作为STC89C52特殊功能（第二功能）使用，如下表所示。在flash编程和校验时，P3口也接收一些控制信号RST: 复位输入。晶振工作时，RST脚持续2个机器周期高电平将使单片机复位。看门狗计时完成后，RST 脚输出96个晶振周期的高电平。特殊寄存器AUXR(地址8EH)上的DISRTO位可以使此功能无效。DISRTO默认状态下，复位高电平有效。ALE/PROG：地址锁存控制信号（ALE）是访问外部程序存储器时，锁存低8 位地址的输出脉冲。在flash编程时，此引脚（PROG）也用作编程输入脉冲。在一般情况下，ALE 以晶振六分之一的固定频率输出脉冲，可用来作为外部定时器或时钟使用。然而，特别强调，在每次访问外部数据存储器时，ALE脉冲将会跳过。如果需要，通过将地址为8EH的SFR的第0位置 “1”，ALE操作将无效。这一位置 “1”，ALE 仅在执行MOVX 或MOVC指令时有效。否则，A
