AT80C51RD2中文资料8051 MCU数据手册Microchip规格书

描述 Description

High-performance version of the 80C51 8-bit microcontrollers that retains all features of the 80C52 adn adds programmable counter array, 1024 bytes of XRAM, hardware watchdog timer, keyboard interface, versatile serial channel that facilitates multiprocessor communication (EUART), and a speed improvement mechanism (X2 mode). The device has two software-selectable modes of reduced activity and an 8-bit clock prescaler to further reduce power consumption. In idle mode, the CPU is frozen while the peripherals and the interrupt system operate. In the power-down mode, the RAM is saved and all other functions are inoperative.

简介

AT80C51RD2属于集成电路（IC）的微控制器。由制造生产的AT80C51RD2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。
