The AT89C55 is a low-power, high-performance CMOS 8-bit microcomputer with 20K bytes of Flash programmable and erasable read only memory. The device is manufactured using Atmel’s high density nonvolatile memory technology and is compatible with the industry standard 80C51 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 AT89C55 is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications.

AT89C55是一低力量,有20K字节的高效的CMOS８位微型电子计算机闪光可编程并且可删除仅仅读存储器。设备被生产高使用Atmel’s密度 nonvolatile存储器技术并且与工业兼容标准的80C51指令集和pinout。在薄片上闪光允许程序存储器是重新规划在里面系统或由一常规的 nonvolatile存储器程序员。由把一万用的８位CPU与相结合在一块整体的芯片上闪光,Atmel AT89C55是提供的有力的微型电子计算机一高度灵活并且花去有效的解决方案到嵌入的许多控制应用程序。
