Microchip Technology Inc. announces new industrial-grade SPE products that will help fulfill SPE’s promise, from 10BASE-T1S MAC-PHYs that more easily connect edge IoT devices to the cloud, to industrial versions of its 100BASE-T1 Time Sensitive Networking (TSN) Ethernet PHY transceivers and switches that enable higher-speed applications across far-reaching Ethernet networks. Microchip’s new LAN8650 and LAN8651 10BASE-T1S MAC-PHY Ethernet Controllers with Serial Peripheral Interface (SPI) simplify the implementation of zonal architectures by enabling basic MCUs, rather than higher-level MCUs with a Media Access Controller (MAC), to be used when creating sensors, actuators and other devices for the edge of OT and IT networks. These low-speed devices do not need their own communication system, and Microchip’s MAC-PHYs connect them to a standard Ethernet system all the way to the cloud over simple twisted-pair wiring.
For industrial applications that require higher bandwidth, designers can use MCUs with an integrated Ethernet MAC. Microchip now offers an industrial-grade version of its LAN8770100BASE-T1 Ethernet PHY Transceiver that provides 100 Mbps transmit and receive capability over a single Unshielded Twisted Pair (UTP) cable.
Microchip’s SPE portfolio is enhanced with industrial-grade versions of its LAN937x and LAN938x Gigabit Ethernet TSN Switches with integrated 100BASE-T1 PHYs. These scalable, secure, and compact SPE switches include hardware time-stamping features for supporting IEEE 802.1AS (gPTP) and IEEE 1588v2 (PTP) time synchronization, among other TSN functionality. Energy-efficiency features include ultra-deep-sleep power down with remote wake for battery applications.
To support the design efforts of these new products a set of network analysis tools and evaluation boards are available including the LAN8651 EVB and EVB-LAN9383. Microchip’s MPLAB Harmony v3 provides software support to configure, debug, and program designs, while the MPLAB Network Creator provides a quick and intuitive graphical interface for switch configuration.
Microchip’s LAN8650 and LAN8651 10BASE-T1S MAC-PHYs and it’s LAN937x and LAN938x 100BASE-T1 Ethernet Switches and LAN8770 100BASE-T1 Ethernet PHY are available for purchase.
