• Execute-in-Place (XIP) systems
• Embedded data storage

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, temperature grade, and lead-free status. Confirm that the required sector configuration matches the device's hybrid or uniform sector options. Ensure compatibility with host system voltage levels within the specified 2.7 V to 3.6 V range. Check for any recent product change notices regarding pinout or electrical specifications.

Memory IC Selection Notes

Select this component when a 128 Mb density SPI NOR flash with high-speed Quad I/O capabilities is required. It is suitable for designs needing AutoBoot functionality and advanced security features like individual sector protection. Consider the 8-WSON package if space constraints exist. Verify that the host controller supports the necessary SPI modes and command sets for Multi-I/O operations.

Memory IC Part Context

This part belongs to the FL-S family of SPI flash memories, which are compatible with prior FL-K and FL-P families in terms of command set and footprint. It utilizes 65-nm process lithography and the Eclipse architecture for improved performance compared to floating gate technologies. The device offers migration paths for existing designs while providing enhanced features such as extended addressing and hardware ECC.

Memory IC Replacement Considerations

S25FL128SAGNFI000 is listed as a manufacturer-recommended substitute.

Memory IC FAQ

Does the S25FL127S support Deep Power Down?

No, the Deep Power Down function is not supported in FL-S family devices. The legacy DPD command code is instead used to enable legacy SPI memory controllers to access the bank address register.

What is the erase command limitation for 4-KB sectors?

The 4-KB erase command is supported only for use on the sixteen 4-KB parameter sectors located at the top or bottom of the device address space. It cannot be used on other sectors if the uniform sector configuration is selected.
