Memory IC Procurement Notes

Verify the specific suffix 'GY' against the manufacturer's current datasheet to confirm the exact package dimensions and tape-and-reel or tray specifications. Confirm that the 200 MHz speed grade aligns with your system's timing requirements, as other variants in the series may operate at lower frequencies. Ensure the industrial temperature range meets your environmental design constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when a compact 8-pin WSON footprint is required for space-constrained designs. The 200 MHz performance level suits applications needing faster boot times compared to standard 166 MHz variants. Verify compatibility with existing PCB layouts regarding the 6x8 mm package outline. Consider the industrial temperature rating if the deployment environment exceeds standard commercial limits.

Memory IC Part Context

This part belongs to the GD25F family of SPI NOR Flash memories from GigaDevice. The series offers densities ranging from 512Kb to 2Gb, targeting diverse market segments including automotive and consumer electronics. The GD25F series is characterized by high reliability and support for various I/O bus configurations, providing scalable storage solutions for embedded applications requiring code execution directly from memory.

Memory IC Replacement Considerations

Check for GD25F256FWIGR or GD25F256FBARY if different packaging or speed grades are acceptable. Verify pinout compatibility before substituting with other 256 Mbit SPI NOR devices from different manufacturers.
