UPD75P108B - 4-BIT SINGLE-CHIP MICROCOMPUTER

Datasheet Summary

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.

Features

Version with on-chip PROM, allowing low-voltage operation VDD = 2.7 to 6.0 V.
µPD75108 compatible.
Memory capacity.
Program memory (PROM) : 8064 × 8 bits.
Data memory (RAM) : 512 × 4 bits.
Correspondence to QTOP™ microcomputer.

DATA SHEET MOS INTEGRATED CIRCUIT µPD75P108B 4-BIT SINGLE-CHIP MICROCOMPUTER 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. Be sure to read for designations. µPD751×× Series User’s Manual : IEM-922 FEATURES • Version with on-chip PROM, allowing low-voltage operation VDD = 2.7 to 6.
