1. Description

TS80C54/58X2 is high performance CMOS ROM, OTP and EPROM versions of the

80C51 CMOS single chip 8-bit microcontroller.

The TS8 0C54/58X2 retains a ll fe atures of the Atmel 80 C51 with e xtend ed

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 a Hardware Watchdog Timer, a more versatile serial

channel that facilitates multiprocessor communication (EUART) and a X2 speed

improvement mechanism.

The fully static design of the TS80C54/58X2 allows to reduce system power consump-

tion by bringing the clock frequency down to any value, even DC, without loss of data.
