Memory IC Procurement Notes

Verify the specific suffix 'GR' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure the ordering part number matches the exact voltage and temperature grade requirements. Cross-reference the 8-WSON package dimensions with your PCB footprint library. Confirm RoHS compliance status through the latest environmental declaration documents provided by GigaDevice Semiconductor.

Memory IC Selection Notes

Select this component when a compact, high-density non-volatile storage solution is required for embedded applications. The SPI interface simplifies PCB routing compared to parallel NAND options. Consider the internal ECC feature if host processor overhead must be minimized. Verify that the 120 MHz maximum clock speed meets the system's performance requirements. Ensure the operating voltage aligns with the target platform's power supply rails.
