September 25, 2025 /SemiMedia/ — Microchip Technology has introduced its LAN9645xF and LAN9645xS gigabit Ethernet switches, targeting industrial, aerospace and data center applications that require high reliability and flexible configurations.

The new devices come in 5-, 7- and 9-port options with up to five integrated 10/100/1000BASE-T PHYs. The LAN9645xF supports advanced features such as Time-Sensitive Networking (TSN) and Audio Video Bridging (AVB), along with hardware redundancy compliant with IEC 62439-3 standards for PRP and HSR protocols. This ensures zero packet loss and seamless failover in critical environments.

The LAN9645xS version, positioned as a lower-cost alternative, provides basic Ethernet switching with some Precision Time Protocol (PTP) support, making it suitable for unmanaged deployments. Both devices integrate with Microchip’s broader ecosystem, including MCUs, memory and timing products, to deliver scalable networking solutions.

Samples of the LAN9645xF and LAN9645xS switches are now available, supported by dedicated evaluation boards and development tools. For more information, please visit https://www.microchip.com/en-us/products/high-speed-networking-and-video/ethernet/ethernet-switches.
