AT80C51RA2-SLSUM 概述

Atmel TS8xC51Rx2 is a high performance CMOS ROM, OTP, EPROM and ROMless versions of the 80C51 CMOS single chip 8-bit microcontroller. The TS8xC51Rx2 retains all features of the 80C51 with extended ROM/EPROM capacity (16/32/64 Kbytes), 256 bytes of internal RAM, a 7-source , 4-level interrupt system, an on-chip oscilator and three timer/counters. In addition, the TS80C51Rx2 has a Programmable Counter Array, an XRAM of 256 or 768 bytes, a Hardware Watchdog Timer, a more versatile serial channel that facilitates multiprocessor communication (EUART) and an X2 speed improvement mechanism.

The fully static design of the TS80C51Rx2 allows to reduce system power consumption by
bringing the clock frequency down to any value, even DC, without loss of data. The TS80C51Rx2 has 2 software-selectable modes of reduced activity for further reduction in power consumption. In the idle mode the CPU is frozen while the timers, the serial port and the interrupt system are still operating. In the power-down mode the RAM is saved and all other functions are inoperative.
