THANK YOU FOR SUBSCRIBING
FREMONT, CA: Microchip Technology, a provider of microcontroller, mixed-signal, analog and Flash-IP solutions, releases three-port, 10/100 industrial Ethernet switches to provide multiple microcontroller data interfaces for maximum flexibility.
LAN9353, LAN9354 and LAN9355 are high-performance, small-footprint, full-featured 3-port managed Ethernet switches. Featuring the IEEE 1588-2008 Precision Time-stamp Protocol (PTP) standard for clock accuracy in the sub-nanosecond range, the new switches offload both synchronization and communications processing from the host CPU. Its transparent clocking feature helps developers to improve system accuracy. The Energy Efficient Ethernet (IEEE802.3az), and Wake On LAN features are designed to reduce overall system power consumption.
The key features of the three new Ethernet switches include:
The LAN9353/9354/9355 switch combines all of the functions of a 10/100 system, including the switch fabric, packet buffers, buffer management, MACs, PHY transceivers and optional serial management functions. All the three devices comply with IEEE 802.3 10BASE-T and 100BASE-TX Ethernet protocol specifications, enabling compatibility with industry standard Ethernet and Fast Ethernet applications. The virtual PHY feature simplifies software development by mimicking multiple switch ports as a single-port PHY and allows system designers to swap the single PHY and Ethernet switch to create multiple SKUs from the same software driver.
To ensure easy installation and network expansion as well as minimal maintenance, these switches also support 100BASE-FX fiber and copper along with cable diagnostics. By enabling system designers and their end users to determine faults, length and shorts in, the switches provide a cost-effective way to extend Ethernet networks over long distances
Three Microchip evaluation boards have also been launched to 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 the new evaluation boards is supported by a Software Development Kit (SDK), which enables developers to immediately start device evaluation, familiarize themselves with features, and begin building solutions for their applications.
"In a world that is becoming increasingly connected to the Internet of Things, Ethernet has emerged as the de-facto wired interconnect standard. Industrial-control manufacturers and IT professionals have embraced this standard, and need compelling new connectivity options for their designs. By expanding our portfolio of full-featured Ethernet switches, Microchip is demonstrating its commitment to being the most reliable Ethernet solutions partner in the industry, offering engineers high-performance devices that feature flexibility and ease of integration," Mitch Obolsky, VP of USB and Networking Group, Microchip Technology.
