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
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.
µPD75216A User’s Manual: IEM-988
