Microchip Technology LAN938x 100BASE-T1 Gigabit Ethernet Switches are scalable, compact, and cost-effective multi-port switches based on the IEEE 802.3bw-2015 specification. These devices feature a layer-2+ managed Ethernet switch with up to five 100BASE-T1 PHY transceivers (four for LAN9381/2, five for LAN9383/4), up to three MAC ports, and an Arm® Cortex® M7 CPU subsystem. The LAN938x family features 2MB of integrated flash memory and a hardware security engine, offering a comprehensive single-chip AVB/TSN bridge solution. The LAN9382/4 models also offer a 100BASE-TX port for applications requiring an automotive OBD connection. Microchip Technology LAN938x switches are available in two temperature ranges and are AEC-Q100 qualified for use in gateways, advanced driver assistance systems (ADAS), infotainment, telematics, and in-vehicle networking systems.
