Overview

IN80C31N/IN80C51N CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER The 80C31/80C51 is a high-performance microcontroller fabricated with high-density CMOS technology.

The 80C51 contains a 4k x 8 ROM , a 128 x 8 RAM , 32 I/O lines, two 16-bit counter/timers, a five-source, two-priority level nested interrupt structure, a serial I/O port for either multi-processor communications, I/O expansion or full duplex UART, and onchip oscillator and clock circuits.

The device has two software selectable modes of power reduction  idle mode and power-down mode.
