uPD78P064B Datasheet | Renesas

DESCRIPTION The µPD78P064B is a product of µPD78064B subseries in 78K/0 series, in which the on-chip mask ROM of the µPD78064B is replaced by one-time PROM. As program write by user is possible, the µPD78P064B 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. µPD78064B Subseries User’s Manual: U10785E 78K/0 Series User’s Manual Instruction: U12326E FEATURES - Pin patible with mask ROM products (except the VPP pin) - Internal PROM: 32K bytes One-time programming possible (most suitable for small-scale production) - Internal high-speed RAM: 1024 bytes - 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 microputers Remarks 1. 2. For the differences between PROM products and mask ROM products, refer to 1. DIFFERENCES BETWEEN µPD78P064B AND MASK ROM PRODUCTS. QTOP Microputer is the general name for a total support as far as writing service, marking, screening, and verification after programming one-time PROM internal signal-chip microcontroller offered by NEC.
