Description
The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4K bytes of Flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set and pinout. The 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 Flash on a monolithic chip, the Atmel AT89C51 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications.
Function characteristic
The AT89C51 provides the following standard features: 4K bytes of Flash, 128 bytes of RAM, 32 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator and clock circuitry. In addition, the AT89C51 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 continue functioning. The Power-down Mode saves the RAM contents but freezes the oscillator disabling all other chip functions until the next hardware reset.
描述
AT89C51是一個低電壓，高性能CMOS8位單片機帶有4K字節(jié)的可反復擦寫的程序存儲器（PENROM）。和128字節(jié)的存取數據存儲器（RAM），這種器件采用ATMEL公司的高密度、不容易丟失存儲技術生產，并且能夠與MCS-51系列的單片機兼容。片內含有8位中央處理器和閃爍存儲單元，有較強的功能的AT89C51單片機能夠被應用到控制領域中。
功能特性
AT89C51提供以下的功能標準：4K字節(jié)閃爍存儲器，128字節(jié)隨機存取數據存儲器，32個I/O口，2個16位定時/計數器，1個5向量兩級中斷結構，1個串行通信口，片內震蕩器和時鐘電路。另外，AT89C51還可以進行0HZ的靜態(tài)邏輯操作，并支持兩種軟件的節(jié)電模式。閑散方式停止中央處理器的工作，能夠允許隨機存取數據存儲器、定時/計數器、串行通信口及中斷系統(tǒng)繼續(xù)工作。掉電方式保存隨機存取數據存儲器中的內容，但震蕩器停止工作并禁止其它所有部件的工作直到下一個復位。
