Memory IC Procurement Notes

Verify the manufacturer origin, as this component was originally produced by Spansion before its acquisition by Cypress Semiconductor, which is now part of Infineon Technologies. Confirm that the specific suffix matches the required voltage and speed grades. Ensure compatibility with the target system's power supply rails, specifically the 1.7 V to 1.95 V operating range. Check for moisture sensitivity levels if reflow soldering is planned.

Memory IC Selection Notes

Select this component when a small form factor is required alongside high-performance parallel interface capabilities. It is appropriate for designs where direct execution from flash is necessary without intermediate buffering. Consider the thermal characteristics and the specific pinout of the 24-FBGA package during PCB layout. Ensure the host controller supports the required synchronous timing protocols for reliable communication.

Memory IC Part Context

This part belongs to the HyperFlash KS series, designed to bridge the gap between traditional NOR flash and NAND flash performance. It offers faster read speeds than standard NOR while maintaining simpler interface requirements compared to NAND. The series is widely used in applications demanding rapid code execution and high reliability in embedded environments.

Memory IC Replacement Considerations

Check for equivalent parts within the S26KL or S26KS families from Infineon or Cypress. Verify pin-to-pin compatibility and electrical specifications before substitution. Ensure any replacement maintains the same package type and voltage requirements to avoid redesign efforts.
