The information in this document is subject to change without notice.
16/8-BIT SINGLE-CHIP MICROCONTROLLER
The
PD78P4038, 78K/IV Series' product, is a one-time PROM or EPROM version of the
PD784035,
PD784036,
PD784037, and
PD784038 with internal masked ROM.
Since user programs can be written to PROM, this microcontroller is best suited for evaluation in system
development, manufacture of small quantities of multiple products, and fast start-up of applications.
For specific functions and other detailed information, consult the following user's manual.
This manual is required reading for design work.

Caution The EPROM versions of the
PD78P4038 are not intended for use in mass-produced products;
they do not have reliability high enough for such purposes. Their use should be restricted to
functional evaluation in experiment or trial manufacture.
