UPD75P4308

DATA SHEET MOS INTEGRATED CIRCUIT µPD75P4308 4-BIT SINGLE-CHIP MICROCONTROLLER The µPD75P4308 replaces the µPD754304’s internal mask ROM with a one-time PROM and features expanded ROM capacity. Because the µPD75P4308 supports programming by users, it is suitable for use in prototype testing for system development using the µPD754302 and 754304 products, and for use in small-lot production. Detailed descriptions of functions are provided in the following document. Be sure to read the document before designing. µPD754304 User’s Manual: U10123E FEATURES Compatible with µPD754304 Memory capacity: · PROM : 8192 × 8 bits · RAM : 256 × 4 bits Can operate in the same power supply voltage as the mask version µPD754304 · VDD = 1.8 to 5.5 V Adopts a compact shrink SOP package ORDERING INFORMATION Part Number Package 36-pin plastic shrink SOP (300 mil, 0.8 mm pitch) µPD75P4308GS Caution On-chip pull-up resistors by mask option are not provided.
