TS80C51RA2/RD2  
TS83C51RB2/RC2/RD2  
TS87C51RB2/RC2/RD2  
High Performance 8-bit Microcontrollers  
1. Description  
Atmel Wireless & Microcontrollers TS80C51Rx2 is high 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.  
performance CMOS ROM, OTP, EPROM and ROMless  
versions of the 80C51 CMOS single chip 8-bit  
microcontroller.  
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.  
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.
