Microchip Technology Inc. (Nasdaq: MCHP) today announces new industrial-grade SPE products that will help fulfill SPE’s promise, from 10BASE-T1S MAC-PHYs that more easily connect edge IIoT 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 is helping to fuel the adoption of zonal architectures in industrial applications with our new MAC-PHYs that connect to many of Microchip’s microcontrollers (MCUs) to reduce the design complexity and implementation costs for bringing a host of sensors, actuators and other products into the new 10BASE-T1S network infrastructure,” said Matthias Kaestner, vice president at Microchip. “With these new 10BASE-T1S MAC-PHYs and industrial versions of our 100BASE-T1 TSN products, we are making it easier to connect the physical world to the cloud while enabling a seamless Ethernet architecture throughout the IIoT and other industrial 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 into 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 LAN8770 100BASE-T1 Ethernet PHY Transceiver that provides 100 Mbps transmit and receive capability over a single Uns...
