DATA SHEET

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

FEATURES

• µPD75308 compatible

• Memory capacity

• Program memory (PROM): 8064 x 8 bits

• Data memory (RAM): 512 x 4 bits

• Can be connected to a pull-up resistor through software: Ports 0-3, 6, 7

• Open-drain input/output: Ports 4 and 5

• Single power source: 5V ± 5%
