Memory IC Procurement Notes

Verify the specific suffix Y2GR against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with 1.65V-2.0V power domains. Confirm industrial temperature grade requirements match design needs. Cross-reference ordering information with manufacturer documentation to avoid substitution errors.

Memory IC Selection Notes

Select this component for designs requiring 512Mb density with low voltage operation between 1.65V and 2.0V. Consider the GD25LT series for applications needing DTR interface support and integrated ECC. Evaluate package options such as WSON8 or TFBGA24 based on board space constraints. Verify that the required temperature range aligns with the specified industrial grades.

Memory IC Part Context

This part belongs to the GD25/55 SPI NOR Flash family, which targets diverse market segments from consumer electronics to automotive systems. The GD25LT series specifically focuses on low-voltage applications, supporting 1.65V to 3.6V ranges. These products are designed for high performance, low power consumption, and high reliability, often featuring smaller packages for space-constrained designs.

Memory IC Replacement Considerations

Check for GD25LT512 variants with different suffixes for alternative packaging or temperature grades. Compare with GD25T512 series for similar density but potentially different voltage ranges. Verify pinout and command set compatibility before substituting with other SPI NOR Flash devices.
