DATA SHEET

MOS INTEGRATED CIRCUIT

PD75P108B

4-BIT SINGLE-CHIP MICROCOMPUTER

DESCRIPTION

The

PD75P108B is a version of the

PD75108 in which the on-chip mask ROM is replaced by one-time

PROM which can be written to once only, or EPROM which is capable of program write, erasure and rewrite.

Also, since the

PD75P108B is capable of program write by a user, it can easily be exchanged with the mask

version, allowing evaluation at low voltage.

Detailed functional descriptions are shown in the following User’s Manual. Be sure to read for designations.

PD751×× Series User’s Manual : IEM-922
