Microchip’s Ethernet Switches Set a New Bar for Industrial Network Flexibility and Redundancy
Key Launch: TSN/AVB and Hardware-Assisted Redundancy in LAN9645xF/S Series
Microchip Technology has raised the bar for industrial Ethernet with its newly launched LAN9645xF and LAN9645xS switch families. Announced September 18, 2025, these gigabit switches offer configurations with 5, 7, or 9 ports—including up to 5 integrated 10/100/1000BASE-T PHYs—to meet the highly specific requirements of industrial networking and control systems.
Configurable Designs Drive Adoption Across Industrial and Infrastructure Sectors
The flexibility to operate in unmanaged stand-alone setups or managed mode (with full Linux® DSA support) means these switches are poised for broad adoption, from factory automation and process control to data centers and defense. Microchip’s design ensures these devices can slot into legacy architectures or enable state-of-the-art network management without additional hardware changes.
Advanced Redundancy and Time-Sensitive Networking Stand Out
The LAN9645xF variant particularly shines in environments where zero downtime is critical. Its support for Time-Sensitive Networking (TSN) and Audio Video Bridging (AVB) enables precise timing and guaranteed packet delivery—vital for industrial automation and synchronized communication. Hardware-assisted redundancy, compliant with the IEC 62439-3 standard for both Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR), minimizes packet loss during faults or failures, ensuring network reliability even in adverse conditions.
| Switch Variant | Port Options | Key Features | Redundancy |
|---|---|---|---|
| LAN9645xF | 5, 7, 9 | TSN/AVB, Managed, Linux DSA | PRP/HSR Hardware-Assisted |
| LAN9645xS | 5, 7, 9 | Unmanaged, Low-Cost, Some PTP | None |
Designed for Demanding Markets: Industry, Aerospace, and More
These new switches slot seamlessly into Microchip’s existing ecosystem of MCUs, memory, and timing solutions, making them especially attractive for designers looking to standardize on a reliable platform. Beyond manufacturing floors, they are positioned for applications in aerospace, defense, and sustainable infrastructure where uptime, reliability, and configurability can’t be compromised.
Support Tools Simplify Integration and Evaluation
To further accelerate deployment, Microchip is backing the LAN9645xF/S line with robust development tools—including the LAN96459 EDS2 Daughter Card (for managed solutions) and the LAN96459 Unmanaged Base Board for more basic needs. This investment in hardware and Linux-based software tools is designed to shorten the path from prototype to production, and help engineering teams quickly realize complex, redundant, and time-sensitive network designs.
Bottom Line: Microchip’s Flexible Ethernet Switches Could Shape the Next Generation of Industrial Networking
The combination of configurability, TSN/AVB support, and built-in redundancy means Microchip is pushing to become a central player in the industrial Ethernet landscape. For investors and engineers alike, this launch highlights Microchip’s commitment to solving real-world network reliability challenges in mission-critical environments. As adoption grows in smart factories, energy, and aerospace, it will be worth watching how quickly these switches are picked up by customers looking for robust, future-proof networking solutions.
