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.
