Preliminary

TS80C52X2

8-bit CMOS Microcontroller 0-60 MHz

1. Description

TEMIC TS80C52X2 is high performance CMOS ROM,

OTP, EPROM and ROMless versions of the 80C51

CMOS single chip 8-bit microcontroller.

The TS80C52X2 retains all features of the TEMIC

80C51

with

extended

ROM/EPROM

capacity

(8

Kbytes), 256 bytes of internal RAM, a 6-source , 4-level

interrupt system, an on-chip oscilator and three timer/

counters.

In addition, the TS80C52X2 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 TS80C52X2 allows to

reduce system power consumption by bringing the clock

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

data.

The TS80C52X2 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.
