MOS INTEGRATED CIRCUIT

PD78042F, 78043F, 78044F, 78045F

8-BIT SINGLE-CHIP MICROCOMPUTER

The

PD78042F,

PD78043F,

PD78044F, and

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.
