µPD75206
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The µPD75206 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 µPD75206, the µPD75P216A, 75P218 one-time PROM products are available for system development 5
evaluation or small production.
Detailed functions, etc. are described in the following user's manual. Be sure to read the manual for designing.
