PD75212A
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The
µ
PD75212A 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
µ
PD75212A is a version of the
µ
PD75216A with a small ROM capacity (12K).
The
µ
PD75212A 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.
