Microchip's 8840/41 LAN devices are transceivers Gigabit Ethernet from a
single port that provide the PTP-v2 (IEEE 1588-2008) timestamp for
highly coordinated automation of factories and processes
Industrial automation system developers try to avoid reliance on proprietary solutions for process synchronization and to adopt standards-based solutions that offer greater compatibility and lower design costs. For the synchronization of critical processes, Microchip Technology Inc. announces the LAN8840 and LAN8841 Gigabit Ethernet transceiver devices, which meet IEEE standards® 1588v2 for the PTP (Precision Timing Protocol) protocol. LAN8840/41 Ethernet devices work with Linux drivers® and offer flexible Ethernet speed options such as 10BASE-T, 10BASE-Te, 100BASE-TX, and 1000BASE-T.
LAN8840/41 devices can facilitate the prioritization of critical packets by providing a high-speed timestamp that is then transmitted to the various components to determine network latencies, adapt to these latencies, and synchronize all network latencies. connected devices. This functionality is essential in process automation applications that require precisely controlled production systems, such as robotics, distributed sensors, and cooling and mixing systems. Designed with applications that require the highest robustness in mind, the LAN8840/41 devices are capable of withstanding extreme industrial temperatures between -40°C and +105°C.
“The new single-port LAN8840/41 transceivers complete our TSN (Time Sensitive Networking) offering by providing connectivity for end nodes in process automation applications,” said Charles Forni, vice president of the USB and Networking business unit. from Microchip. "These devices complement our existing portfolio for Ethernet and provide our customers with an end-to-end network solution made up of components, development tools and support from Microchip."
To help businesses meet their sustainability goals by reducing the power consumption of a network, the LAN8840/41 devices offer features such as Wake-on-LAN (WoL) and Wi-Fi Shutdown mode. Energy.
In addition, EEE (Energy-Efficient Ethernet) includes low-power sleep and stop-clock modes to optimize power consumption.
Microchip is a consolidated provider of solutions for industrial networks that offers a wide catalog of robust and highly integrated products. The new LAN8840/41 devices are especially suitable for markets where applications require accurate and precise time stamping, such as gas and chemical processing, power distribution and foreign exchange systems, which need to demonstrate their synchronization with the NIST (National Institute of Standards and Technology) according to UTC (Universal Coordinated Time) with a margin of one millisecond or finer increments.
