AT89C51ID2中文资料8051 MCU数据手册Microchip规格书

描述 Description

High-performance CMOS flash version of the 80C51 CMOS, single-chip, 8-bit microcontroller with a 64KB flash memory block for program and data. The flash memory can be programmed in parallel or serial mode using ISP or software. The programming voltage is internally generated from the standard VCC pin. This device retains all features of the Microchip 80C52 and adds a programmable counter array, 1792 byte XRAM, a hardware watchdog timer, SPI and keyboard, a more versatile serial channel that facilitates multiprocessor communication (EUART), and a speed improvement mechanism (X2 mode).A fully static design reduces system power consumption by bringing the clock frequency down to any value without data loss. Two software-selectable modes of reduced activity and an 8-bit clock prescaler further reduce power consumption.

简介

AT89C51ID2属于集成电路（IC）的微控制器。由制造生产的AT89C51ID2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。
