P25Q32SL-SSH-IR

The P25Q32SL is a serial interface flash memory device designed for the large volume of consumer applications that require code to be loaded from flash memory into embedded or external RAM for execution. The device's flexible erase architecture and page erase granularity also make it an ideal solution for data storage, eliminating the need for additional data storage devices. Its erase block sizes are optimized to meet today's code and data storage application requirements. By optimizing erase block sizes, storage space can be utilized more efficiently. Since certain code modules and data storage segments must reside independently within their own erase regions, wasted and unused storage space can be significantly reduced compared to flash memory devices that employ large sector and block erase operations. This improved storage space 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 OTP (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 2.0V. No separate voltage is required for programming and erasing.
