DATA SHEET 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.
