    Device Overview

    Summary

    The Microchip LAN8770 is a compact, cost-effective, single-port 100BASE-T1 Ethernet physical layer transceiver compliant with the IEEE 802.3bw-2015 specification. The device provides 100 Mbit/s transmit and receive capability over a single Unshielded Twisted Pair (UTP) cable.

    The LAN8770 is available in a Grade 1 Automotive (-40°C to +125°C) temperature range and is optimized for AEC-Q100 automotive use cases such as Automated Driver-Assistance Systems (ADAS), infotainment, telematics, smart antennas, and in-vehicle backbones. In addition, the family is Microchip Functional Safety Ready; specifically designed to simplify customers end-product ISO26262 safety certification with the support of specialized hardware safety features, Failure Modes, Effects, and Diagnostic Analysis (FMEDA) and safety manual.

    Microchip’s LAN8770 EtherGREEN™ energy efficient technology provides low-power 100BASE-T1 PHY operation along with support for OPEN Alliance TC10 with an ultra low-power sleep and wake-up mode. FlexPWR® variable I/O and core power supply voltages provide flexible design options and power saving opportunities. Advanced PHY diagnostics provide the user with troubleshooting capabilities such as the Signal Quality Indicator (SQI), LinkMD® cable defect detection), over-temperature, under-voltage protection, comprehensive status interrupt support, and various loopback and test modes.

    Microchip's complimentary and confidential LANCheck® online design review service is available for customers who have selected our products for their application design-in. The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
