Memory IC Procurement Notes

Verify the specific suffix 'UEYIGR' against the manufacturer's official datasheet to confirm the exact voltage range (2.7V-3.6V), temperature grade (-40°C to +85°C), and package type (WSON-8). Ensure compatibility with host controller SPI modes and check for any recent product change notifications or end-of-life status updates from GigaDevice before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a cost-effective alternative to SPI NOR flash is needed for higher density storage. It is suitable for designs requiring low pin counts and simplified PCB layouts compared to parallel NAND. Consider the internal ECC feature if host-side error correction resources are limited. Verify that the 120MHz clock speed meets the system's throughput requirements for read and write operations.
