D78CP18

DATA SHEET MOS INTEGRATED CIRCUIT µPD78CP18(A) 8-BIT SINGLE-CHIP MICROCOMPUTER DESCRIPTION The µPD78CP18(A) is a version of the µPD78C18(A) in which the internal mask ROM is replaced by one-time PROM. The one-time PROM version can be programmed once only by users, and is ideally suited for small-scall of many differnt products, and rapid development and time-to-market of a new product. The detailed functions are descrived in the following user's manual. Read this manual before starting design work. 87AD series µPD78C18 user's manual: IEU-1314 FEATURES High reliability compared to the µPD78CP18 Compatible with the µPD78C11A(A), 78C12A(A), 78C14(A), 78C18(A) Internal PROM: 32768 W × 8 Internal PROM capacity can be changed by software to conform to the µPD78C11A(A), 78C12A(A), 78C14(A), 78C18(A). PROM programming characteristics: µPD27C256A compatible www.DataSheet.net/ Power supply voltage range: 5 V ± 10 % Supports QTOP™ microcomputer Remark QTOP microcomputer is the generic name of NEC's single-chip microcomputers for which NEC provides total service including writing, marking, screening, and inspection. 5 ORDERING INFORMATION Part Number Package 64-pin plastic QFP (14 × 20 mm) 64-pin plastic QUIP Internal ROM One-time PROM One-time PROM µPD78CP18GF(A)-3BE µPD78CP18GQ(A)-36 QUALITY GRADE Part Number Quality Grade Special Special µPD78CP18GF(A)-3BE µPD78CP18GQ(A)-36 Please refer to “Quality grade on NEC Semiconductor Devices” (Document number IEI-1209)...
