Three-Port, 10/100 Industrial Ethernet Switches

Microchip’s LAN9353, LAN9354 and LAN9355 Three-Port, 10/100 Industrial Ethernet Switches enable the development of advanced hardware in the rapidly growing Industrial Ethernet market, including automation, motion-control, embedded, automotive, security/surveillance and telecommunications applications.

Featuring the IEEE 1588-2008 Precision Time-stamp Protocol (PTP) standard for clock accuracy in the tens-of-nanoseconds range, these parts offload both synchronization and communications processing from the host CPU. You can also take advantage of advanced features such as Transparent Clocking, which improves system accuracy. These devices also incorporate Energy Efficient Ethernet (IEEE802.3az) and Wake On LAN to reduce overall system power consumption.

The LAN9353, LAN9354 and LAN9355 support widely adopted industry standards such as Media Independent Interface (MII), Reduced Media Independent Interface (RMII), Serial Management Interface (SMI), Turbo MII, I2C and SPI/SQI™ communication interfaces, along with digital I/O. This gives you the flexibility to select from a wide range of microcontrollers, Systems-on-Chip (SoCs) or processors to interface with this family of switches. To ensure easy installation and network expansion, as well as minimal maintenance, these switches also support 100BASE-FX fibre and copper, along with cable diagnostics that enable system designers and their end users to determine cable opens, shorts, length to fault and cable length, providing a cost-effective way to extend Ethernet networks over long distances.

Evaluation boards are available to support all 3 parts.
