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.
