UPD78P083

Features:

` Pin-compatible with mask ROM version (except V<sub>PP</sub> pin)
` Internal PROM: 24 Kbytes ^Note
    • PD78P083DU: Reprogrammable (ideally suited for system evaluation)
    • PD78P083CU, PD78P083GB: One-time programmable (ideally suited for small-scale production)
` Internal high-speed RAM: 512 bytes <sup>Note</sup>
` Can be operated in the same supply voltage as the mask ROM version (V_DD = 1.8 to 5.5 V)
` Corresponding to QTOP^TM Microcontrollers

Description

The mPD78P083 is a member of the mPD78083 subseries of the 78K/0 series products. It includes an on-chip, 24-Kbyte, one-time PROM or EPROM.

Because this device mPD78P083 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.
