# LAN9646\-I/MXX (Component)

## Description

6\-Port Gigabit Ethernet Switch – Managed Ethernet switch IC providing six Gigabit Ethernet ports with integrated 10/100/1000BASE\-T/TX PHYs\. The Microchip LAN9646\-I/MXX supports SGMII, RGMII, MII, and RMII interfaces, with I²C and SPI management interfaces\. It operates from 1\.2 V and 2\.5 V supply rails, supports IEEE 802\.3 Ethernet, and is housed in a 132\-pin DVQFN \(11 × 11 mm\) package for −40°C to \+85°C operation\.
