4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The
μ
PD75208 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
μ
PD75208, the
μ
PD75P216A, 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
