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.

I Reset: A high on this pin for two machine cycles while the oscillator is running,
resets the device. An internal diffused resistor to VSS permits a power-on reset
using only an external capacitor to VCC. If the hardware watchdog reaches its
time-out, the reset pin becomes an output during the time the internal reset is
activated.
