8-Bit Microcontroller with 8K Bytes Flash AT89C52
1.Description
The AT89C52 is a low-power, high-performance CMOS 8-bit microcomputer with 8K 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 80C51 and 80C52 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 AT89C52 is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications.
AT89C52是美国ATMEL公司生产的低电压,高性能的CMOS 八位单片机,内含8K字节可反复擦写的只读程序存储器(PEROM)和256字节的随机存储数据存储器(RAM),器件采用ATMEL公司高密度,非易失性存储技术生产,与标准MCS-51指令系统和8052产品引脚兼容.片内内置8位中央处理器(CPU)和FLASH存储单元,功能强大的AT89C52单片机适合许多较为复杂的控制场所.
