Procurement Notes
Verify the current lifecycle status before procurement, as availability may be limited. Confirm that the 40-QFN package dimensions match the target PCB footprint. Ensure the operating temperature range aligns with the environmental requirements of the final assembly. Check for any recent Product Change Notifications regarding assembly sites or labeling changes.
Selection Notes
Select this component when a dedicated PHY controller with a parallel interface is required for 10/100 Mbps Ethernet connections. Consider the 40-QFN package size constraints and the specific voltage supply requirements of 3.14V to 3.47V. Evaluate thermal management needs given the exposed pad design for heat dissipation during continuous operation.
