IN80C32N

The IN80C32N 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 reductionidle 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 of the IN80C32N saves the RAM contents but freezes the oscillator, causing all other chip functions to be inoperative.
