1 / 80 page  µPD78P324, 78P324(A) MOS INTEGRATED CIRCUIT The information in this document is subject to change without notice. 16-/8-Bit Single-Chip Microcomputers © 1991, 1995 DATA SHEET The µPD78P324 is a product in which the µPD78324’s internal mask ROM is replaced by a one-time PROM or EPROM. The one-time PROM product, which enables writing only once, is effective for multiple-device small production of sets or early start of mass-production. The EPROM product, which enables program writing, deletion, and rewriting, is the most suitable for system evaluation. The µPD78P324(A) is more reliable than the µPD78P324. The µPD78P324(A) is a product resulting from the µPD78324(A) whose internal mask ROM is replaced by a one-time PROM. For details of functions, please refer to the following User’s Manual. Reading this manual is indispensable especially for designing work. µPD78322 User’s Manual: IEU-1248 FEATURES q µPD78324 compatible • For mass-production, this can be replaced by the µPD78324 incorporated in the mask ROM. q Minimum instruction run time: 250 ns (with the external clock operating at 16 MHz): µPD78P324 & 78P324(A) 320 ns (with the external clock operating at 12.5 MHz): µPD78P324(A1) & 78P324(A2) q Internal PROM: 32768 x 8 bits • Writing enabled only once (windowless one-time PROM product) • Elimination by ultraviolet light and electrical rewriting enabled (EPROM product with window): µPD78P324 only q ECC circuit incorporated • High internal PROM content reliablility possible q PROM programming characteristic: µPD27C1001A compatible q QTOPTM microcomputer compatible Remark A QTOP microcomputer is a single-chip microcomputer with one-time PROM for which program writing, marking, screening, and verifying is completely supported by NEC. APPLICATION FIELDS q µPD78P324: Fields dealing with motor control equipment. q µPD78P324(A), 78P324(A1), and 78P324(A2): Automotive and transportation equipments, etc. This document describes the µPD78P324, 78P324(A), µPD78P324(A1), and µPD78P324(A2) as well. However, unless there are particular differences, the µPD78P324 is described as a representative product. PROM is the representative term used for the part common to both the one-time PROM product and the EPROM product. Document No. IC-2857 (O. D.
