UPD78P322 Overview
DATA SHEET MOS Integrated Circuit µPD78P322 16/8-BIT SINGLE-CHIP MICROCONTROLLER The µPD78P322 is a version provided by replacing the µPD75322's internal mask ROM with one-time PROM or EPROM. Because the one-time PROM version is programmable only once by users, it is ideally suited for small-scale production of many different products, and rapid development and time-to-market of application sets. The EPROM version...
UPD78P322 Key Features
- For mass-production, the µPD78P322 can be replaced with the µPD78322 which incorporates mask ROM
- Internal PROM: 16,384 × 8 bits
- Programmable once only (one-time PROM version without window)
- Erasable with ultraviolet rays and electrically programmable (EPROM version with window)
