MOS INTEGRATED CIRCUIT

µPD75208

4-BIT SINGLE-CHIP MICROCOMPUTER

DESCRIPTION

The µPD75208 is a microcomputer with a CPU capable of 1-, 4-, and 8-bit-wise data processing, a ROM, a RAM,

I/O ports, a fluorescent display tube controller/driver, a watch timer, a timer/pulse generator capable of outputting

14-bit PWM, a serial interface and a vectored interrupt function integrated on a single-chip.

It uses the VCR, ECR and CD fluorescent display tubes as display devices and is most suitable for applications

requiring the timer/watch function and high-speed interrupt servicing. It can help to provide the unit with many

functions and to decrease performance costs.

With the µPD75208, the µPD75P216A, 75P218 one-time PROM products are available for system development 5

evaluation or small production.

The following manual provides detailed description of the functions of the µPD75208. Be sure to read this manual

when you design an application system.
