UPD75517A Overview
ELECTRON DEVICE DATA SHEET MOS INTEGRATED CIRCUIT µPD75517(A) 4 BIT SINGLE-CHIP MICROPUTER The µPD75517(A) is a 75X series four-bit single-chip microputer which enables data processing equivalent to that performed by an eight-bit microputer. It is a high-performance product, whose minimum instruction execution time is 0.67 µs, shorter than 0.95 µs for the conventional µPD75516. The ROM and RAM capacities are also...
