AT89C52数据手册集成电路（IC）的微控制器规格书PDF

描述 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.\r
\r
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.

简介

AT89C52属于集成电路（IC）的微控制器。由制造生产的AT89C52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。
