LAN9303MI-AKZE

Controllers Overview

The LAN9303MI-AKZE is a full-featured, three-port managed Ethernet switch designed for embedded applications. It integrates a high-performance switch fabric with 32K buffer RAM and a 512-entry forwarding table. The device supports IEEE 802.3 10BASE-T and 100BASE-TX standards, along with 802.1D/802.1Q network management protocols. It features two internal 10/100 PHYs with HP Auto-MDIX support and a Virtual PHY for host connection via MII/RMII/Turbo MII interfaces. Turbo MII mode enables speeds up to 200Mbps. Management is handled via I2C or SMI slave controllers, and it includes an I2C master EEPROM controller. The component operates on a single 3.3V supply and provides ±8kV HBM ESD protection.
