uPD78P064 Datasheet | Renesas

DESCRIPTION The µPD78P064 is a product of µPD78064 subseries in 78K/0 series, in which the on-chip mask ROM of the µPD78064 is replaced by one-time PROM or EPROM. As program write by user is possible, the µPD78P064 is best suited for evaluation, short-run and multiple-device production, and early rise upon system development. Functions are described in detail in the following User’s Manuals, which should be read when carrying out design work. µPD78064, 78064Y Subseries User’s Manual : U10105E 78K/0 Series User’s Manual Instruction : U12326E FEATURES - Pin patible with mask ROM products (except the VPP pin) - Internal PROM: 32K bytes Note - µPD78P064KL-T : Reprogrammable (ideal for system evaluation) - µPD78P064GC, 78P064GF: Programmable once only (ideal for small-scale production) - Internal high-speed RAM: 1024 bytes Note - LCD display RAM: 40 × 4 bits - Operable in the same supply voltage as mask ROM products (VDD = 2.0 to 6.0 V) - Corresponding to QTOPTM microcontrollers Note Internal PROM and internal high-speed RAM capacities can be changed by memory size switching register (IMS). Remarks 1. 2. For the differences between PROM products and mask ROM products, refer to 1. DIFFERENCES BETWEEN µPD78P064 AND MASK ROM PRODUCTS. A QTOP microcontroller is the general name for a single-chip microcontroller with one-time PROM for which program writing, marking, screening, and verifying are pletely supported by NEC. In this document, “PROM” is used in parts mon to one-time PROM products and EPROM products. The information in this document is subject to change without notice. Document No. U12589EJ3V0DS00 (3rd edition) (Previous No. IC-3224) The mark shows major revised points.
