Microchip LAN9381/2/3/4

7-port 100BASE-T1 gigabit Ethernet switch

The LAN9381/2/3/4 is a scalable, compact and cost-effective, multi-Port AVB/TSN 100BASE-T1 Ethernet Switch family based on the IEEE 802.3bw-2015 specification. The LAN938x incorporates a layer-2+ managed high-performance Ethernet switch, up to five (four for the LAN9381/2, five for the LAN9383/4) 100BASE-T1 physical layer transceivers (PHYs), up to three MAC ports, and an ARM Cortex M7 CPU subsystem. With the addition of integrated 2MB code flash memory and a hardware security engine, the LAN938x family delivers a fully integrated, single-chip AVB/TSN bridge solution.
