DATA SHEET MOS INTEGRATED CIRCUIT µPD78CP18(A) 8-BIT SINGLE-CHIP MICROPUTER 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 pared to the µPD78CP18 - patible 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 patible - Power supply voltage range: 5 V ± 10 % - Supports QTOP™ microputer Remark QTOP...
