AT89C55WD数据手册集成电路（IC）的微控制器规格书PDF

描述 Description

Low-power, high-performance CMOS 8-bit microcontroller with 20KB of flash programmable ROM and 256 bytes of RAM. The device is manufactured using Microchip high-density nonvolatile memory technology and is compatible with the industry standard 80C51 and 80C52 instruction set and pinout. On-chip flash allows the program memory to be user programmed by a conventional nonvolatile memory programmer. This versatile 8-bit CPU with flash is a highly flexible and cost-effective solution for many embedded control applications.

简介

AT89C55WD属于集成电路（IC）的微控制器。由制造生产的AT89C55WD微控制器微控制器产品是相对复杂的用户可编程数字逻辑器件。这些产品与视为微控制器的器件密切相关，两者之间的区别主要体现在制造商选择的用词。不过按照传统，微控制器集成了工作存储器，也更可能包含混合信号外设，并且往往与更简单的软件范例结合使用，旨在重复执行一系列预定义的任务。
