µPD75108F,75112F,75116F
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The µPD75116F offers high-speed operation (tCY = 1.91 µs) at a low supply voltage (VDD = 2.7 V) which is not possible
with the µPD75116.
It has the same functions as, and is pin compatible with, the µPD75116, 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 µPD75116.
A version of the µPD75116F with on-chip PROM, the µPD75P116*, is also available for evaluation during system
development.
* There are some differences in electrical specifications between the µPD75116F and the µPD75P116.
Functions are described in detail in the following User’s Manual, which should be read when carrying out design
work.
