UPD78P322

DATA SHEET MOS Integrated Circuit µPD78P322 16/8-BIT SINGLE-CHIP MICROCONTROLLER The µPD78P322 is a version provided by replacing the µPD75322's internal mask ROM with one-time PROM or EPROM. Because the one-time PROM version is programmable only once by users, it is ideally suited for small-scale production of many different products, and rapid development and time-to-market of application sets. The EPROM version is reprogrammable, and suited for the evaluation of systems. The µPD78P322K, which is the EPROM version, does not maintain planned reliability when used in mass-produced products. Please use only experimentally or for evaluating functions during trial manufacture. Functions are described in detail in the following user's manual. Be sure to read it for designing. µPD78322 User's Manual: IEU-1248 FEATURES µPD78322 compatible For mass-production, the µPD78P322 can be replaced with the µPD78322 which incorporates mask ROM Internal PROM: 16,384 × 8 bits Programmable once only (one-time PROM version without window) Erasable with ultraviolet rays and electrically programmable (EPROM version with window) PROM programming characteristics: µPD27C256A compatible The µPD78P328 is a QTOPTM microcontroller Remark QTOP microcontroller is a general term for microcontrollers which incorporate one-time PROM, and are totally supported by NEC's programming service (from programming to marking, screening, and verification).
