PD75108F,75112F,75116F
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The
µ
PD75116F offers high-speed operation (t
CY
= 1.91
µ
s) at a low supply voltage (V
DD
= 2.7 V) which is not possible
with the
µ
PD75116.
It has the same functions as, and is pin compatible with, the
µ
PD75116, allowing low voltage sets to be developed
by making efficient use of previously developed and used software resources. Note, however, that the operating
voltage range is different from that of the
µ
PD75116.
A version of the
µ
PD75116F with on-chip PROM, the
µ
PD75P116*, is also available for evaluation during system
development.
*
There are some differences in electrical specifications between the
µ
PD75116F and the
µ
PD75P116.
Functions are described in detail in the following User’s Manual, which should be read when carrying out design
work.
