PUYA P25Q40SH Flash is a feature rich and cost-optimized serial peripheral interface (SPI) non-volatile NORflash family. This application note provides conversion guidelines for migrating from the P25Q40H to theP25Q40SH Flash.This application note is based on information available to date from datasheets and other application notespublicly available from PUYA. Please refer also to the latest relevant specifications. The document discussesthe specification differences when migrating from P25Q40H to P25Q40SH.
PUYA P25Q40H products are well suited for migration to PUYA P25Q40SH products. Some of the reasons arecompatible pinouts, packages, command set, and 4KB sector structure. Both P25Q40H and P25Q40SHdevices support Single (Standard) I/O, Dual I/O, and Quad I/O modes. The main differences betweenP25Q40H and P25Q40SH are listed in the table below:
