DESCRIPTION

The

µ

PD75P308 is a model of the

µ

PD75308 equipped with a one-time PROM or EPROM instead of an

internal mask ROM.

Two types are available as the

µ

PD75P308. The one-time PROM type is ideal for production of a small

quantity of many different types of application systems as data can only be written once to the one-time

PROM of this type. Programs can be written and rewritten to the built-in EPROM type making it ideal

for system evaluation.

Detailed functions are described in the followig user's manual. Be sure to read it for designing.
