DESCRIPTION
The
μ
PD75P316B is a product of the
μ
PD75316B with its built-in ROM having been replaced with the one-
time PROM.
It is most suitable for test production during system development and for production in small amounts since
it can operate under the same supply voltage as mask products.
The one-time PROM product is capable of writing only once and is effective for production of many kinds of
sets in small quantities and early startup.
The EPROM product allows programs to be written and rewritten, making it ideal for system evaluation.
Functions are described in detail in the following User'S Manual, which should be read when carrying out
design work.

Please refer to “Quality grade on NEC Semiconductor Devices” (Document number IEI-1209) published by
NEC Corporation to know the specification of quality grade on the devices and its recommended applications.
The information in this document is subject to change without notice.
The
μ
PD75P316B EPROM product does not provide a level of reliability suitable for use as a
volume production product for customers' devices. The EPROM product should be used solely for
function evaluation in experiments or preproduction.
In descriptions common to one-time PROM products and EPROM products in this document, the term
"PROM" is used.
