GENERAL DESCRIPTION
The
ICSI IC80C51 and IC80C31 are high-performance
microcontroller fabricated using high-density CMOS
technology. The CMOS IC80C51/31 is functionally
compatible with the industry standard 80C51/31
microcontrollers.
The IC80C51/31 is designed with 4K x 8 ROM (IC80C51
only); 128 x 8 RAM; 32 programmable I/O lines; a serial I/
O port for either multiprocessor communications, I/O
expansion or full duplex UART; two 16-bit timer/counters;
an six-source, two-priority-level, nested interrupt structure;
and an on-chip oscillator and clock circuit. The IC80C51/31
can be expanded using standard TTL compatible memory.
