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

1. Description

and EPROM versions of the 80C51 CMOS single chip

8-bit microcontroller.

The TS80C54/58X2 retains all features of the Atmel

Wireless & Microcontrollers

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.

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.

2. Features

Rev. C - 15 January, 2001

80C52 Compatible

High-Speed Architecture

Dual Data Pointer

On-chip ROM/EPROM (16K-bytes, 32K-bytes)

Programmable Clock Out and Up/Down Timer/

Counter 2

Hardware Watchdog Timer (One-time enabled with

Reset-Out)

Asynchronous port reset

8051 pin and instruction compatible

Four 8-bit I/O ports

Three 16-bit timer/counters

256 bytes scratchpad RAM

40 MHz @ 5V, 30MHz @ 3V

X2 Speed Improvement capability (6 clocks/

machine cycle)

30 MHz @ 5V, 20 MHz @ 3V (Equivalent to

60 MHz @ 5V, 40 MHz @ 3V)

80C51 with extended

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.

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.
