Data Sheet
Description
The
µ
PD75116(A) is one of the 4-bit single-chip micro-
computer 75X series.
The
µ
PD75116(A) is a product with the extended ROM
capacity of the
µ
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
µ
PD75116
have been improved by a wide variety of bit control
instructions. The
µ
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
µ
PD75116(A), an on-chip pin-compatible one-time
PROM product (
µ
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.

Unless there are any particular functional differences,
the
µ
PD75116(A) is described in this document as a
representative product.
