UPD75P108B, 4-BIT SINGLE-CHIP MICROCOMPUTER

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
