com S71WS512N to S71WS512P Migrating from the S71WS512N to the S71WS512P Application Note by Daisuke Nakata 1.
Introduction Migrating from the S71WS512N to the monolithic S71WS512P is a simple process; however, the user should be aware of a few differences between these two parts.
These differences are the result of the S71WS512N using two S29WS256N die in series while the S71WS512P uses a single S29WS512P configuration.
This application note describes these differences in detail so users currently using the S71WS512N configuration can plan ahead and include the necessary software to ensure a smooth migration to the S71WS512P.
Both software and hardware considerations are covered.
