UPD75P116

DATA SHEET MOS INTEGRATED CIRCUIT µPD75P116 4-BIT SINGLE-CHIP MICROCOMPUTER DESCRIPTION The µPD75P116 is a version of the µPD75116 in which the on-chip mask ROM is replaced by one-time PROM which can be written to once only. Since the µPD75P116 is capable of program write by a user, it is suitable for evaluation in system development and limited production. Detailed functional descriptions are shown in the following User’s Manual. Be sure to read for design purposes. µPD751×× Series User’s Manual : IEM-922 FEATURES µPD75116 compatible Program memory (PROM) capacitance : 16256 × 8 bits Data memory (RAM) capacitance : 512 × 4 bits Single power supply 5 V ± 10% ORDERING INFORMATION Ordering Code Package 64-pin plastic shrink DIP (750 mil) 64-pin plastic QFP (14 × 20 mm) Quality Grade Standard Standard 5 µ PD75P116CW µ PD75P116GF-3BE Please refer to “Quality Grade on NEC Semiconductor Devices” (Document number IEI-1209) published by NEC Corporation to know the specification of quality grade on the devices and its recommended applications.
