Microchip has announced the addition of the LAN9353, LAN9354 and LAN9355 Three-Port, 10/100 Industrial Ethernet Switches to its portfolio of Ethernet solutions, which includes Ethernet switches, controllers, bridges and PHYs.
Featuring the IEEE 1588-2008 Precision Time Protocol (PTP) standard for clock accuracy in the sub-nanosecond range, these integrated Ethernet switches offload both synchronisation and communications processing from the host CPU. Developers can also take advantage of advanced features such as Transparent Clocking, which is said to improve system accuracy. Additional features designed to reduce overall system power consumption include Energy Efficient Ethernet and Wake On LAN.
These switches enable the development of advanced hardware in the Industrial Ethernet market, including automation, motion-control, embedded, automotive, security/surveillance and telecommunications applications.
The LAN9353/4/5 Ethernet switches support multiple industry standards giving designers the flexibility to select from a range of MCUs, SoCs or processors to interface with this new series of switches.
Three Microchip evaluation boards, EVB-LAN9353/4/5 have also been released that demonstrate how to interface with the switches through I/O connections or with MCUs such as the 32-bit PIC32MX family via serial communications.
The Ethernet Switches are available in 64-pin QFN and TQFP-EP for the LAN9353; 56-pin QFN for the LAN9354; and 88-pin QFN and 80-pin TQFP-EP for the LAN9355.
