AC320004-4 - LAN9303 PHY Switch Daughter Board

Part Number: AC320004-4

Microchips LAN9303 Switch PHY Daughter Board is populated with a high-performance, small-footprint, full-featured 3-port managed LAN9303 Ethernet switch and a 2 port Base-TX MAGJACK connector. It is designed for easy development of RMII Ethernet control applications when plugged into the PIC32 compatible Starter Kits.

The LAN9303 Switch PHY Daughter Board (AC320004-4) enables Ethernet communication with the starter kits listed below.

PIC32MZ EC Starter Kit
PIC32MZ EC Starter Kit with Crypto Engine 
PIC32 Ethernet Starter Kit II


    • High-performance, full-featured 3-port switches with per-port IEEE 802.1Q VLAN support (up to 16 VLAN groups)
    • Industry's highest (±8kV/15kV) per-port ESD protection
    • IGMP v1/v2 monitoring for multicast packet filtering
    • Up to 200 Mbps network speed via a Turbo MII interface
    • Optional EEPROM or external CPU serial management support via an I2C™ interface
    • Virtual PHY feature simplifies software development by mimicking multiple switch ports as a single-port PHY
    • Integrated regulators require a single 3.3V supply
