UPD75P108B Datasheet 4-bit Single-chip Microcomputer

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD75P108B 4-BIT SINGLE-CHIP.

General Description

The µPD75P108B is a version of the µPD75108 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 µPD75P108B 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.
