LAN8710AI-EZK-TR

Product Overview

The LAN8710AI-EZK-TR from Microchip Technology is a 100 Mbps full-duplex transceiver for MII and RMII interfaces. It provides four drivers and four receivers, allowing simultaneous transmit and receive paths in full-duplex operation. The device uses a 32-VFQFN Exposed Pad package, with a 32-QFN 5x5 surface-mount footprint, and supports supply voltages from 1.6V to 3.6V over an operating temperature range of -40°C to 85°C. It is suited to interface-level connectivity where a compact package and media-independent interface signaling are required.

Key Features

Applications

• Media-independent interface connectivity in communication modules
• Full-duplex 100 Mbps data transmission between interface devices
• Low-voltage interface circuits powered from 1.6V to 3.6V supply rails
• Surface-mount integration where a 32-QFN 5x5 exposed-pad footprint is suitable

Design & Procurement Notes

Design considerations include confirming that the host interface supports either MII or RMII and that the system supply remains within 1.6V to 3.6V. The 32-QFN 5x5 package with exposed pad requires surface-mount assembly and appropriate pad layout for the exposed-pad package. The full-duplex 100 Mbps data rate and four-driver/four-receiver configuration define the available interface resources, while the -40°C to 85°C range should be checked against the board-level thermal environment. When evaluating the part for a design, compare the package dimensions and exposed-pad layout with the intended PCB assembly process.
