Memory IC Procurement Notes

Verify the specific suffix 'E' against official datasheets to confirm the 8-USON package and 1.65V-2V voltage range, as generic GD25LQ40 variants may differ in package type or operating voltage. Ensure the source document explicitly lists GD25LQ40ESIGR to avoid confusion with similar models like GD25LQ40CTIGR or GD25LQ40ETIGR which have different electrical or physical specifications.

Memory IC Selection Notes

Select this part when a compact 8-USON footprint is required alongside low-voltage operation between 1.65V and 2V. It is appropriate for designs needing 133 MHz Quad I/O speeds without the higher voltage requirements of 3V-only flash memories. Confirm that the system power rail aligns with the specified operating range before integration.

Memory IC Part Context

This component belongs to the GD25LQ series of SPI NOR Flash memories from GigaDevice. The series targets applications demanding small form factors and low power consumption. The 'LQ' designation typically indicates low voltage operation, while the 'E' suffix in this specific part number denotes the USON package variant.
