DATA SHEET MOS INTEGRATED CIRCUIT µPD78P083 8-BIT SINGLE-CHIP MICROCONTROLLER DESCRIPTION The µPD78P083 is a member of the µPD78083 subseries of the 78K/0 series products. It includes an on-chip, 24-Kbyte, one-time PROM or EPROM. Because this device can be programmed by users, it is ideally suited for applications involving the evaluation of systems in development stages, small-scale production of many different products, and rapid development and time-to-market of a new product. Caution The µPD78P083DU does not maintain planned reliability when used in your systems’ mass-produced products. Please use only experimentally or for evaluation purposes during trial manufacture. The details of functions are described in the user’s manuals. Be sure to read the following manuals before designing. µPD78083 Subseries User's Manual 78K/0 Series User's Manual - Instructions : IEU-1407 : IEU-1372 Features - Pin-patible with mask ROM version (except VPP pin) - Internal PROM: 24 Kbytes Note - µPD78P083DU: Reprogrammable (ideally suited for system evaluation) - µPD78P083CU, µPD78P083GB: One-time programmable (ideally suited for small-scale production) - Internal high-speed RAM: 512 bytes Note - Can be operated in the same supply voltage as the mask ROM version (VDD = 1.8 to 5.5 V) - Corresponding to QTOPTM Microcontrollers Note The internal PROM and internal high-speed RAM capacities can be changed by setting the internal memory size switching register (IMS). 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). - Differs from the mask ROM version in the following points The same memory mapping as the mask ROM version is enabled by setting the internal memory size switching register (IMS). In this document, the term PROM is used in parts mon to one-time PROM versions and EPROM versions. The information in...
