GENERAL DESCRIPTION
The
ICSI
IC80C52 and IC80C32 are high-performance
microcontroller fabricated using high-density CMOS
technology. The CMOS IC80C52/32 is functionally
compatible with is the industry standard 80C52/32
microcontrollers.
The IC80C52/32 is designed with 8K x 8 ROM (IC80C52
only); 256 x 8 RAM; 32 programmable I/O lines; a serial I/
O port for either multiprocessor communications, I/O
expansion or full duplex UART; three 16-bit timer/counters;
an eight-source, two-priority-level, nested interrupt
structure; and an on-chip oscillator and clock circuit. The
IC80C52/32 can be expanded using standard TTL
compatible memory.
