MSM80C31F

CMOS 8-Bit Microcontroller;

GENERAL DESCRIPTION\nThe OKI MSM80C31F/MSM80C51F microcontroller is a low-power, 8-bit device implemented\nin OKI's silicon-gate complementary metal-oxide semiconductor process technology.  The\ndevice includes 4K bytes of mask programmable ROM (MSM80C51F only), 128 bytes of\ndata RAM, 32 I/O lines, two 16-bit timer/counters, a five-source two-level interrupt\nstructure, a full duplex serial port, and an oscillator and clock circuitry.  In addition, the device\nhas two software selectable modes for further power reduction — Idle and Power Down.  Idle\nmode freezes the CPU's in-struction execution while maintaining RAM and allowing the timers,\nserial port and interrupt system to continue functions.  Power Down mode saves the RAM\ncontents but freezes the oscillator causing all other device functions to be inoperative.
