UPD75212ACW-B37

DESCRIPTION

The µPD75212A 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 µPD75212A is a version of the µPD75216A with a small ROM capacity (12K).
The µPD75212A 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.
