Keywords:products MirrorBit migration? S29GL-N S29GL-P? NOR flash?

This application note serves as a guide for customers using the S29GL-N 110nm MirrorBit products to migrate to the S29GL-P 90nm MirrorBit products. It outlines some of the similarities and differences between the products to ease the migration.

The S29GL-N and S29GL-P are basically identical devices maintaining the same Device ID. The process technology migrated from 110nm to 90nm so migration should be easy and seamless. However, there is a minor change in the hardware reset procedure that customers may need to be aware of depending on their system.

In addition, the S29GL-P introduces 32 word write buffer size for the customers who want better programming performance while keeping backward software compatibility with 16 word write buffer size. Finally, the S29GL-P family provides a monolithic 1Gbit NOR device so that very high density code/data storage applications can take advantage of reliable and fast random read features of NOR flash.
