Memory IC Procurement Notes

Verify the specific suffix CE2GR against official datasheets to confirm the 8-USON (3x2mm) package and 90 MHz speed grade. Ensure compatibility with 1.65V-2.1V supply rails. Confirm RoHS3 compliance status if required by regional regulations. Cross-reference manufacturer part numbers to avoid confusion with similar GD25LQ series variants.

Memory IC Selection Notes

Select this component when a small footprint and low voltage operation are critical. The 90 MHz speed offers a balance between performance and power consumption. Compare against standard SOIC packages if board space allows for larger components. Verify that the target system supports Quad I/O protocols for optimal throughput.

Memory IC Part Context

This part belongs to the GD25LQ40C series of low-voltage NOR flash memories. It shares architectural similarities with other members like the GD25LQ40CTIGR but differs in package type and potentially speed grades. The series targets applications demanding high density in minimal physical space while maintaining industrial-grade durability.

Memory IC Replacement Considerations

GD25LQ40CEIGR is a documented variant within the same family, offering similar electrical characteristics but potentially differing in package dimensions or speed specifications. Verify pinout compatibility and voltage tolerances before substitution.
