The PD78P324 is a product in which the PD78324's internal mask ROM is replaced by a one-time PROM or EPROM. The one-time PROM product, which enables writing only once, is effective for multiple-device small production of sets or early start of mass-production. The EPROM product, which enables program writing, deletion, and rewriting, is the most suitable for system evaluation. The PD78P324(A) is more reliable than the PD78P324. The PD78P324(A) is a product resulting from the PD78324(A) whose internal mask ROM is replaced by a one-time PROM. For details of functions, please refer to the following User's Manual. Reading this manual is indispensable especially for designing work. |
