Product Details

LAN9354 3-Port 10/100 Ethernet Switch

The Microchip LAN9354 is a high performance 3-Port 10/100 Managed Ethernet Switch IC with a single RMII.

The device offers a virtual PHY feature that mimics a single PHY connection through the RMII interface to the host SoC that can simplify software development. This feature also allows system designers to swap the single PHY and Ethernet switch to create multiple SKUs from the same software driver.

The LAN9354 integrates all the functions of a 10/100 switch system including the Switch Fabric, Packet Buffers, Buffer Manager, MACs, PHY Transceivers and Serial Management. IEEE 1588v2 is supported via an integrated Hardware Time Stamp Unit, which supports end-to-end and peer-to-peer transparent clocks.


IEEE 802.1Q VLAN support (up to 16 VLAN groups)
IEEE 1588-2008 Hardware Time Stamping Unit
Up to 200 Mbps network speed via a Turbo MII interface
Compliant with IEEE 802.3az Energy Efficient Ethernet
Wake on LAN (WoL) support
IGMP v1/v2 monitoring for multicast packet filtering
Optional EEPROM or external CPU serial management support via an I2C™ interface
Virtual PHY feature to simplify software development by mimicking multiple switch ports as a single-port PHY
Comprehensive power management features
Cable diagnostic support
Integrated regulators requiring a single 3.3 V supply
42 per-port MIB counters for efficient network management
