UPD78P322 Description
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...
