TS80C51RA2/RD2

TS83C51RB2/RC2/RD2

TS87C51RB2/RC2/RD2

High Performance 8-bit Microcontrollers

1. Description

Atmel Wireless & Microcontrollers TS80C51Rx2 is high

performance CMOS ROM, OTP, EPROM and ROMless

versions of the 80C51 CMOS single chip 8-bit

microcontroller.

The TS80C51Rx2 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 a 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.
