UPD75P308

DATA SHEET MOS INTEGRATED CIRCUIT µPD75P308 4-BIT SINGLE-CHIP MICROCOMPUTER DESCRIPTION The µPD75P308 is a model of the µPD75308 equipped with a one-time PROM or EPROM instead of an internal mask ROM. Two types are available as the µ PD75P308. The one-time PROM type is ideal for production of a small quantity of many different types of application systems as data can only be written once to the one-time PROM of this type. Programs can be written and rewritten to the built-in EPROM type making it ideal for system evaluation. Detailed functions are described in the followig user's manual. Be sure to read it for designing. µ PD75308 User's Manual: IEM-5016 FEATURES µ PD75308 compatible Memory capacity Program memory (PROM): 8064 x 8 bits Data memory (RAM): 512 x 4 bits Can be connected to a pull-up resistor through software: Ports 0-3, 6, 7 Open-drain input/output: Ports 4 and 5 Single power source: 5V ± 5% ORDERING INFORMATION Part Number Package 80-pin plastic QFP (14 x 20 mm) 80-pin ceramic WQFN (LCC w/window) Internal ROM One-time PROM EPROM µPD75P308GF-3B9 µPD75P308K QUALITY GRADE Part Number Package 80-pin plastic QFP (14 x 20 mm) 80-pin Ceramic WQFN (LCC w/window) Quality Grade Standard Standard 5 µPD75P308GF-001-3B9 µPD75P308K 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.
