AT89S8253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 12KB of ISP flash program memory and 2KB of EEPROM data memory. The device is manufactured using Microchip high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51?? instruction set and pinout. On-chip downloadable flash allows the program memory to be reprogrammed in-system through an SPI serial interface or by a conventional nonvolatile memory programmer. This versatile 8-bit CPU with downloadable flash provides a highly-flexible and cost-effective solution for many embedded control applications.

简介

AT89S8253属于集成电路（IC）的微控制器。由制造生产的AT89S8253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。
