PD75112(A), 75116(A)

4-Bit Single Chip-Microcomputer

Data Sheet

Description

The

PD75116(A) is one of the 4-bit single-chip micro-

computer 75X series.

The

PD75116(A) is a product with the extended ROM

capacity of the

PD75108(A). In addition of high-speed

operations, it can manipulate data in units of 1, 4 and 8

bits. In particular, the I/O operation of the

PD75116

have been improved by a wide variety of bit control

instructions. The

PD75116 is provided with interface

inputs/outputs with peripheral circuits having different

power voltages, and analog inputs and suitable for

controlling automobile electrical equipment, etc. For

the

PD75116(A), an on-chip pin-compatible one-time

PROM product (

PD75P116) is separately available for

system development evaluation.

Functions are described in detail in the following User’s

Manual, which should be read when carrying out

design work.
