2. Description

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
