Procurement Notes

Verify the specific package variant required, as the FT25H16 is available in multiple packages including SOP8, DIP8, VSOP8, and TSSOP8. Confirm that the ordering suffix matches the desired physical footprint and pin pitch. Check for availability status as component lifecycles may change. Ensure compatibility with the target system's voltage levels and SPI interface requirements before procurement.

Selection Notes

Select this component when a 16M-bit capacity is needed with support for high-speed Quad SPI operations. Consider the FT25H16 for designs requiring robust write protection features and security register locks. Evaluate the available package options against the PCB layout constraints. Ensure the operating voltage range of 2.7V to 3.6V aligns with the system power supply.

Part Context

The FT25H16 belongs to the FT25H series of serial flash memories from Fremont Micro Devices Ltd. This series is designed for applications requiring reliable non-volatile storage with flexible interface options. The device utilizes a uniform block and sector architecture for efficient data management and erasure operations.

Replacement Considerations

SST25WF040B-40I/SN is listed as a similar substitute part number by Microchip Technology. Verify electrical characteristics, pinout compatibility, and command set alignment before substitution. Note that the substitute has different density specifications and requires validation for the specific application requirements.
