• Industrial control systems requiring 10 Mbps connectivity
• Consumer electronics with limited space constraints
• Automotive information entertainment systems

Controllers Procurement Notes

Verify the specific suffix indicating package type and temperature range when ordering. Confirm RoHS compliance status as manufacturing sources may vary between original SMSC and subsequent Microchip production runs. Ensure compatibility with existing EEPROM configuration files if replacing legacy components.

Controllers Selection Notes

Select this component for applications requiring integrated 10 Mbps Ethernet without external PHY dependencies. Consider the available processor interface options to match the target system bus architecture. Evaluate power consumption requirements against the device's sleep mode capabilities for battery-operated designs.

Controllers Part Context

The LAN91C96 series was originally developed by SMSC and later acquired by Microchip Technology. It serves as a cost-effective solution for embedding network capabilities into microcontroller-based systems. The QFP variant denotes the Quad Flat Package form factor used in surface-mount assemblies.

Controllers Replacement Considerations

Direct pin-to-pin replacements are limited due to the age of the component. Review Microchip's current Ethernet controller portfolio for modern alternatives with higher speed support and updated interface standards.
