Features, Applications

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 mode freezes the CPU's in-struction execution while maintaining RAM and allowing the timers, 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 2 mm silicon gate CMOS process technology Fully static circuit Internal program memory : 4K bytes (MSM80C51F) External program memory space : 64K bytes Internal data memory (RAM) : 128 bytes External data memory (RAM) space : 64K bytes I/O ports ¥ 4 ports Two 16-bit timer/counters Multifunctional serial port (UART) Five interrupt sources (Priority can be set) Four sets of working registers ¥ 4) Stack : Internal data memory (RAM) 128-byte area can be used arbitrarily (by SP specified) Two CPU power-down modes (1) Idle mode : CPU stopped while oscillation continued. (Software setting) (2) PD mode : CPU and oscillation all stopped. (Software setting) (Setting I/O ports to floating status possible) Operating temperature +85°C 12 MHz, VCC +70°C 16 MHz, VCC 2-byte 1-machine cycle instructions : 1 msec. @ 12 MHz 0.75 msec. @ 16 MHz Multiplication/division instructions : 4 msec. @ 12 MHz 3 msec. @ 16 MHz Instruction code addressing method Byte specification : Data addressing (direct) Bit specification : Bit addressing

Operating frequency to 16 MHz..................... to 12 MHz..................... MSM80C31/MSM80C51/MSM80C31F/MSM80C51F External clock input terminal XTAL2................................. MSM80C31/MSM80C51 Emulation mode Output impedance of ALE and PSEN pins becomes about 20 kW while CPU is being reset in MSM80C31F/MSM80C51F. Any other functions and electrical characteristics of MSM80C31F/MSM80C51F except for above three differences are the same as those of MSM80C31/MSM80C51.
