• Compatible with standard 10Base-T Ethernet protocols

Controllers Applications

• Industrial automation systems
• Consumer electronics networking
• Automotive infotainment interfaces

Controllers Procurement Notes

Verify the manufacturer designation as Microchip Technology, which acquired SMSC. Confirm the specific suffix 'ME' matches the required package and temperature grade. Ensure RoHS compliance status aligns with project requirements, noting potential discrepancies in third-party listings.

Controllers Selection Notes

Select this component for applications requiring a dedicated 10 Mbps Ethernet MAC without PCI bus integration. Consider the AUI interface requirement and the QFN-56 EP footprint during PCB layout. Validate power supply stability across the specified 3.3 V to 5 V operating range.

Controllers Part Context

This part belongs to the LAN91C93 series of Ethernet controllers. The series provides standalone solutions for network connectivity. The 'I' suffix typically denotes industrial temperature range operation, while 'MS' or 'ME' indicates specific package variations.
