TS80C31X2

8-bit CMOS Microcontroller ROMless

1. Description

TS80C31X2 is high performance CMOS and ROMless The fully static design of the TS80C31X2 allows to

reduce system power consumption by bringing the clock

frequency down to any value, even DC, without loss of

data.

versions of the 80C51 CMOS single chip 8-bit

microcontroller.

The TS80C31X2 retains all features of the TSC80C31

with 128 bytes of internal RAM, a 5-source, 4 priority

level interrupt system, an on-chip oscilator and two timer/

counters.

The TS80C31X2 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.

In addition, the TS80C31X2 has a dual data pointer, a

more versatile serial channel that facilitates

multiprocessor communication (EUART) and a X2 speed

improvement mechanism.
