Procurement Notes
Verify component authenticity through authorized distributors as the part may be obsolete. Confirm package integrity and pin compatibility before integration. Check current availability status due to potential end-of-life designation. Ensure supply chain documentation matches Renesas Electronics Corporation specifications for quality assurance.
Selection Notes
Select this component for applications requiring integrated 10/100Base-TX PHY functionality. Consider the 64-pin TQFP package constraints for PCB layout. Verify 3.3-V power supply requirements align with system design. Evaluate thermal performance within the -40°C to +85°C operating range for environmental suitability.
Part Context
This Ethernet PHY controller belongs to Renesas' physical layer solution portfolio. It provides essential connectivity for legacy and standard Ethernet networks. The device simplifies design by integrating transceiver and controller functions into a single package, reducing component count and board space requirements for network interfaces.
Replacement Considerations
No public confirmed substitute part numbers are available. The component status is listed as obsolete. Engineers should consult Renesas Electronics Corporation for current alternatives or design-in support for new projects requiring equivalent 10/100Base-TX PHY capabilities.
