P25Q32SH-SSH-IT Serial Peripheral Interface (SPI) non-volatile NOR flash memory chip
1 Introduction
PUYA P25Q32SH Flash is a feature rich and cost-optimized serial peripheral interface (SPI) non-volatile NOR flash family. This application note provides conversion guidelines for migrating from the P25Q32H to the P25Q32SH Flash.
This application note is based on information available to date from datasheets and other application notes publicly available from PUYA. Please refer also to the latest relevant specifications. The document discusses the specification differences when migrating from P25Q32H to P25Q32SH.
2 Feature Comparison and Differences
PUYA P25Q32H products are well suited for migration to PUYA P25Q32SH products. Some of the reasons are compatible pinouts, packages, command set, and 4KB sector structure. Both P25Q32H and P25Q32SH devices support Single (Standard) I/O, Dual I/O, and Quad I/O modes. The main differences between P25Q32H and P25Q32SH are listed in the table below:
