Memory IC Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging when ordering. Confirm the 8-SOP package width matches your PCB footprint requirements. Ensure voltage levels align with the 2.7V to 3.6V operating range. Check for RoHS3 compliance if required by your manufacturing standards. Validate lead times as availability may vary.

Memory IC Selection Notes

Choose this component for designs requiring moderate density with high-speed interface support. The 8-SOP package suits space-constrained surface-mount applications. Consider the Quad SPI capability if bandwidth is critical. Ensure the host controller supports the necessary SPI modes and instruction sets for optimal performance.
