DATA SHEET MOS INTEGRATED CIRCUIT µPD75328 4-BIT SINGLE-CHIP MICROCOMPUTER DESCRIPTION The µPD75328 is one of the 75X Series 4-bit single-chip microcomputer, and has a data processing capability comparable to that of an 8-bit microcomputer. In addition to high-speed operation with 0.95 µ s minimum instruction execution time for the CPU, the µPD75328 can also process data in 1-, 4-, and 8-bit units. Therefore, as a 4-bit single-chip microcomputer chip having a built-in LCD controller/driver and A/D converter, its data processing capability is the highest in its class in the world. The µPD75P328 with one-time PROM, which is replaced with the internal mask ROM for a µPD75328, is applicable for evaluating systems under development, or for small-scale production of developed systems.
