UPD78CP18A

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 Power supply voltage range: 5 V ± 10 % Supports QTOP™ microcomputer 5 Remark QTOP microcompute...
