Memory IC Procurement Notes

Verify the manufacturer designation carefully, as this part number appears in listings associated with both Infineon Technologies and Nexperia USA Inc. Confirm the specific datasheet version and package details (8-WSON) with the supplier before ordering. Ensure compatibility with your system's voltage levels and interface requirements. Check for moisture sensitivity handling instructions if the component has been stored for extended periods.

Memory IC Selection Notes

Select this component when a 128 Mbit capacity is required with high-speed serial access capabilities. The 133 MHz clock speed makes it suitable for performance-sensitive applications. Consider the 8-WSON package size for board layout constraints. Verify that the 1.7 V to 2 V operating voltage aligns with your system's power rails. Compare against other S25FS128S variants if different pinouts or temperature ranges are needed.

Memory IC Part Context

This part belongs to the S25FS128S series of NOR flash memories. The series is characterized by its use of MirrorBit technology, which allows for high density and reliability. These devices are commonly used in embedded systems where code execution in place (XIP) is beneficial. The specific suffix indicates the package type and temperature range specifications defined by the manufacturer.

Memory IC Replacement Considerations

Direct substitutes include other S25FS128S variants with compatible pinouts and electrical characteristics. Verify that any replacement maintains the same 128 Mbit capacity, SPI/QPI interface support, and 8-WSON package dimensions. Ensure the alternative part meets the same voltage and temperature specifications.
