DATA SHEET
MOS INTEGRATED CIRCUIT
µPD75216A
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The µPD75216A is a microcomputer with a CPU capable of 1-, 4-, and 8-bit data processing, ROM, 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.
The µPD75216A is a product with the ROM capacity and the number of display segments extended for the
µPD75208.
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.
Functions are described in detail in the following User’s Manual. Be sure to read when carrying out design work.
µPD75216A User’s Manual: IEM-988
