Microchip Technology has launched its next generation of LAN9645xF and LAN9645xS Gigabit Ethernet Switches with multi-port configurations and feature options for maximum reliability and flexibility.
The LAN9645xF/S switches provide multiple configurations for specific application needs and are available in five-, seven-, and nine-port options with up to five integrated 10/100/1000BASE-T PHYs. This flexibility is further improved by the ability to operate in either stand-alone unmanaged system configurations or in managed mode with full Linux DSA support on a connected host.
The LAN9645xF device supports advanced features, such as TSN and AVB, in its managed mode of operation. This variant enhances network reliability with hardware-assisted redundancy that meets the IEC 62439-3 standard for Parallel Redundancy Protocol (PRP) and High-Availability Seamless Redundancy (HSR), enabling seamless failover and zero packet loss during faults. At the same time, the LAN9645xS device supports standard Ethernet switching with some PTP support and is intended to be employed 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."
The LAN9645xF/S delivers adaptable, high-performance networking solutions for industrial Ethernet applications, and for markets like aerospace and defence, data centres and sustainability. Also, the Ethernet devices seamlessly integrate with the company's ecosystem, including MCUs, memory and timing solutions, enabling reliable and scalable networks for demanding environments.
The LAN9645xF and LAN9645xS switches are supported by the LAN96459 EDS2 Daughter Card (EV14H52A) for use with a compatible Curiosity EVB, and the stand-alone LAN96459 Unmanaged Base Board (EV03E14A) for unmanaged demonstrations. The LAN96459 EDS2 Daughter Card, when used with a host Curiosity EVB, leverages the Linux DSA software.
