TS80C31X2-ELCD Overview

8-BIT, 40 MHz, MICROCONTROLLER, PQFP44

TS80C31X2
8-bit CMOS Microcontroller ROMless
1. Description
TS80C31X2 is high performance CMOS and ROMless
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.
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.
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.
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.
