TS80C54X2/C58X2

TS87C54X2/C58X2

8-bit CMOS Microcontroller 16/32 Kbytes ROM/OTP

1. Description

TS80C54/58X2 is high performance CMOS ROM, OTP The fully static design of the TS80C54/58X2 allows to

reduce system power consumption by bringing the clock

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

data.

and EPROM versions of the 80C51 CMOS single chip

8-bit microcontroller.

The TS80C54/58X2 retains all features of the Atmel

Wireless & Microcontrollers 80C51 with extended

ROM/EPROM capacity (16/32 Kbytes), 256 bytes of

internal RAM, a 6-source , 4-level interrupt system, an

on-chip oscilator and three timer/counters.

The TS80C54/58X2 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 TS80C54/58X2 has a Hardware

Watchdog Timer, a more versatile serial channel that

facilitates multiprocessor communication (EUART) and

a X2 speed improvement mechanism.
