Microchip LAN9668 TSN Ethernet Switch
Microchip’s new family of time sensitive networking (TSN) ethernet switches provides industry’s first turnkey solution for industrial automation networks.
The LAN9668 is part of a family (LAN966x) of compact and cost-effective, multi-port Gigabit TSN Ethernet Switches with two integrated 10/100/1000BASE-T PHYs and a 600 MHz ARM Cortex A7 CPU subsystem. Complementing the LAN9668x is Microchip’s newly released LAN8814 quad-port Gigabit Ethernet Physical Layer (PHY) transceiver. The LAN9668 includes eight ports.
In addition to the two integrated PHYs, the LAN9668 supports up to 2 RGMII/RMII, up to 3 1000BASE-X/SerDes/2.5GBASE-X/KX, and up to 2 Quad-SGMII/Quad-USGMII interfaces.
Microchip’s LAN9668-I/9MX and LAN9668-9MX devices are 8-port switches for industrial and commercial applications, respectively, outfitted with Arm® Cortex®-A7 central processing units (CPUs), supporting TSN IEEE standards for communication in industrial settings. These include IEEE 1588v2 and IEEE 802.1AS-2020 for Precision Timing, IEEE 802.1Qci for per-stream filtering and policing, IEEE 802.1Qav and IEEE 802.1Qbv for Traffic Shaping and IEEE 802.1CB for Seamless Redundancy, as well as IEC-62439-2 (Media Redundancy Protocol) and ODVA-DLR and IEC-61158-6-10 for Media Redundancy.

Development tools
The LAN9668-I/9MX and LAN9668-9MX TSN Ethernet switches are supported by the VSC6817SDK IStaX Linux Application Software, an industrial Ethernet switch software solution supporting Microchip's managed Ethernet switch devices. The VSC6817SDK IStaX Linux Network Operating System is an industrial Ethernet switch software solution also supporting Microchip's managed Ethernet switch devices. The SMBStaX Linux Network Operating System and WebSTaX Linux Network Operating System are available to commercial designers and follow the long-term support Linux Kernel. These solutions all are highly integrated with advanced L2+ switch features. In addition, reference designs and evaluation boards also are available from Microchip and the company’s distribution partners, enabling easy design-in.
