P25D32SH-SSH-IT

P25D32SH is a serial interface flash memory device designed for high-volume consumer applications where program code is executed from flash mapped into embedded or external RAM. The device features a flexible erase architecture with page erase granularity, making it equally well-suited for data storage, thereby eliminating the need for additional data storage devices. The device's erase block sizes are optimized to meet the demands of today's code and data storage applications. By optimizing erase block sizes, storage space can be utilized more efficiently. Since certain code modules and data storage segments must reside individually within their own erase regions, the wasted and unused storage space typically associated with large-sector and large-block erase flash devices can be significantly reduced. This improved storage efficiency allows additional code routines and data storage segments to be added while maintaining the same overall device density. The device also incorporates an additional 3×1024-byte security register with one-time programmable lock, which can be used for purposes such as device serialization, system-level electronic serial number storage, and lock key storage. The device is designed for use across many different systems, supporting read, program, and erase operations over a wide supply voltage range of 1.65V to 3.6V. No separate voltage is required for programming and erasing.
