AT89S2051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 2KB ISP flash memory. The device uses Microchip high-density nonvolatile memory technology and is compatible with the industry-standard MCS??-51 instruction set. An enhanced CPU core can fetch a single byte from memory every clock cycle and is capable of 20-MIPS throughput. The new CPU core runs at a much lower speed, greatly reducing power consumption.

简介

AT89S2051属于集成电路（IC）的微控制器。由制造生产的AT89S2051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。
