UPD75518 Description
DATA SHEET MOS INTEGRATED CIRCUIT ELECTRON DEVICE µPD75518(A) 4 BIT SINGLE-CHIP MICROPUTER The µPD75518(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...
