4-BIT SINGLE-CHIP MICROCOMPUTER
The PD75216A 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 PD75216A is a product with the ROM capacity and the number of display segments extended for the
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.
