MSM80C31F/MSM80C51F

CMOS 8-Bit Microcontroller

GENERAL DESCRIPTION

The OKI MSM80C31F/MSM80C51F microcontroller is a low-power, 8-bit device implemented

in OKI's silicon-gate complementary metal-oxide semiconductor process technology. The

device includes 4K bytes of mask programmable ROM (MSM80C51F only), 128 bytes of

data RAM, 32 I/O lines, two 16-bit timer/counters, a five-source two-level interrupt

structure, a full duplex serial port, and an oscillator and clock circuitry. In addition, the device

has two software selectable modes for further power reduction — Idle and Power Down. Idle

modefreezestheCPU'sin-structionexecutionwhilemaintainingRAMandallowingthetimers,

serial port and interrupt system to continue functions. Power Down mode saves the RAM

contents but freezes the oscillator causing all other device functions to be inoperative.

FEATURES

• Low power consumption by 2 mm silicon gate CMOS process technology

• Fully static circuit

• Internal program memory

• External program memory space
