PD78043F,
m
PD78044F, and
m
PD78045F are 8-bit single-chip microcomputers that incorpo-
rate many hardware peripherals such as an FIP
controller/driver, 8-bit resolution A/D converter, timer, serial
interface, and interrupt controller.
The one-time PROM and EPROM models that can operate in the same voltage range as that of masked ROM
models, and various development tools are provided.
The functions of these microcomputers are described in detail in the following User’s Manual. Be sure
to read this manual when you design a system using any of these microcomputers.
