MOS INTEGRATED CIRCUIT

μPD75P308

4-BIT SINGLE-CHIP MICROCOMPUTER

DESCRIPTION

The μPD75P308 is a model of the μPD75308 equipped with a one-time PROM or EPROM instead of an internal mask ROM.

Two types are available as the μPD75P308. 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. μPD75308 User's Manual: IEM-5016
