Microchip Introduces Flexible New Family of Gigabit Ethernet Switches with TSN/AVB and Redundancy For Industrial Applications

24 September 2025  

Ethernet technology can provide the high-speed, reliable communication needed to connect and control industrial devices in real time. Its scalability and flexibility to support protocols such as TSN ensures seamless integration for demanding industrial environments.  Microchip Technology has announced the launch of its next generation of LAN9645xF and LAN9645xS Gigabit Ethernet Switches with multi-port configurations and feature options for maximum reliability and flexibility.   

The company says the LAN9645xF/S switches offer multiple configurations for specific application needs and are available in 5-, 7-, and 9-port options with up to 5 integrated 10/100/1000BASE-T PHYs. This flexibility is further enhanced by the ability to operate in either stand-alone unmanaged system configurations or in managed mode with full Linux Distributed Switch Architecture (DSA) support on a connected host.

The LAN9645xF device supports advanced features such as Time-Sensitive Networking (TSN) and Audio Video Bridging (AVB) in managed mode of operation. This variant enhances network reliability with hardware-assisted redundancy that meet IEC 62439-3 standard for Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR), enabling seamless failover and zero packet loss during faults. While the LAN9645xS device supports standard Ethernet switching with some Precision Time Protocol (PTP) support and is intended to be used as a low-cost unmanaged switch.

 “Our LAN9645x F/S devices help our customers lower their system costs while implementing advanced TSN and redundancy features by combining many features into a single solution,” said Charlie Forni, Corporate Vice President of Microchip’s Networking and Communications Business Unit. “We back our products with global technical support and a full suite of development tools to make it easier for our customers to design and deploy their industrial networks.”

 Microchip’s LAN9645xF/S can deliver adaptable, high-performance networking solutions for industrial Ethernet applications, as well as for markets like aerospace and defense, data centres and sustainability. Additionally, the Ethernet devices seamlessly integrate with Microchip’s ecosystem including MCUs, memory and timing solutions, enabling reliable and scalable networks for demanding environments.
