LAN8720AI-CP

Product Overview

The Microchip Technology LAN8720AI-CP is a surface-mount transceiver for embedded communication designs. It supports MII and RMII protocols and provides 2/2 drivers/receivers with full-duplex operation at a 100 Mbps data rate. The device operates from a 1.6 V to 3.6 V supply and has an operating temperature range of -40°C to 85°C. It uses a 24-QFN-EP (4x4) package with an exposed pad for compact board layouts and surface-mount assembly.

Design & Procurement Notes

When selecting this part, confirm that the host device supports the chosen MII or RMII interface and that signal integrity is adequate for 100 Mbps full-duplex operation. Verify that the selected interface mode matches the host device's interface connections and configuration requirements. Review the supply rail to ensure it remains within 1.6 V to 3.6 V under load and transient conditions. The 24-QFN-EP (4x4) exposed-pad package requires a compatible land pattern, solder paste design, and exposed-pad connection review. Specify the exact manufacturer part number and package to avoid mismatches in footprint, pad count, and exposed-pad requirements.
