1. Description
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.
TS80C54/58X2 is high performance CMOS ROM, OTP and EPROM versions of the
80C52 Compatible
