| IN80C39N/IN80C49N CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER The 80C39/80C49 is a high-performance microcontroller fabricated with high-density CMOS technology. The 80C49 contains a 2k x 8 ROM , a 128 x 8 RAM , 27 I/O lines, 8-bit counter/timers, a two-source, one level interrupt structure, and on-chip oscillator and clock circuits. The device has two modes of power reduction idle mode and power-down mode. The idle mode freezes the CPU while allowing the RAM, timer, 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.
