From Microchip come three new 3-port, 10/100 Mbps industrial Ethernet switches. The LAN9353, LAN9354 and LAN9355 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 Protocol (PTP) standard for clock accuracy in the sub-nanosecond range, the chips offload both synchronisation and communications processing from the host CPU. Developers can also take advantage of advanced features such as transparent clocking, which improves system accuracy. Additional features designed to reduce overall system power consumption include Energy Efficient Ethernet (IEEE 802.3az) and Wake On LAN.
The devices support widely adopted industry standards such as MII (Media Independent Interface), RMII (Reduced Media Independent Interface), SMI (Serial Management Interface), Turbo MII, I²C and SPI/SQI communication interfaces, along with digital I/O.
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.
To enable development with the LAN9353/4/5, three evaluation boards are available that support various system architectures. These hardware systems demonstrate how to interface with the switches through basic input/output connections, or with microcontrollers such as the 32-bit PIC32MX family via serial communications. Each of these boards is also supported by a software development kit (SDK), which enables developers to immediately start device evaluation, familiarise themselves with features, and begin building solutions for their applications.
The LAN9353/4/5 are available now for sampling and volume production in low pin-count and small body size packages: 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.
