IN80C32N/IN80C52N CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER The 80C32/80C52 is a high-performance microcontroller fabricated with high-density CMOS technology. The 80C52 contains a 8k x 8 ROM , a 256 x 8 RAM , 32 I/O lines, three 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. The idle mode freezes the CPU while allowing the RAM, timers, serial port, and interrupt system to continue functioning. The power-down mode saves the RAM contents but freezes the oscillator, causing all other chip functions to be inoperative.
