UPD75518A 4 BIT SINGLE-CHIP MICROCOMPUTER

ELECTRON DEVICE DATA SHEET MOS INTEGRATED CIRCUIT µPD75518(A) 4 BIT SINGLE-CHIP MICROCOMPUTER The µPD75518(A) is a 75X series four-bit single-chip microcomputer which enables data processing equivalent to that performed by an eight-bit microcomputer. It is a high-performance product, whose minimum.

Features

• Higher reliable than the µPD75518
