Memory IC Procurement Notes

Verify the specific package variant required, as the GD25LB16E series includes SOP8, USON8, and WSON8 options. Confirm that the system power supply aligns with the 1.65V to 2.1V operating range. Ensure compatibility with the default Quad Enable bit setting which cannot be changed. Check for RoHS compliance requirements if applicable to your manufacturing process.

Memory IC Selection Notes

Select this component when a low-voltage operation between 1.65V and 2.1V is required. It is suitable for designs needing high-speed data access via Quad SPI or QPI modes. Consider the available package types such as USON8 or WSON8 for space-constrained PCB layouts. Ensure the application benefits from the uniform sector architecture for simplified memory management.

Memory IC Part Context

This part belongs to the GD25LB16E family of Serial NOR Flash memories. The 'I' suffix typically indicates an industrial temperature range, while 'GR' denotes tape and reel packaging.
