1 / 30 page  LAN8670/1/2 10BASE-T1S Ethernet PHY Transceiver Product Brief Description The LAN8670/1/2 is a high-performance 10BASE-T1S single-pair Ethernet PHY transceiver for 10 Mbit/s half- duplex networking over a single pair of conductors. Utilizing standard Ethernet technology in sensor/ actuator networks reduces application costs by eliminating gateways necessary with legacy networking technologies. The ability to connect multiple PHYs onto a common mixing segment further saves implementation costs by reducing cabling and switch ports. The LAN8670/1/2 is designed for use in high-reliability cost sensitive industrial, backplane, and building automation sensor/actuator applications. Highlights • High-performance 10BASE-T1S Ethernet PHY • Designed according to IEEE Std 802.3cg-2019 ™ – 10 Mbit/s over single balanced pair – Half-duplex point-to-point link segments up to at least 15m – Half-duplex multidrop mixing segments up to at least 25m with up to at least 8 PHYs • Media Independent Interface (MII) and Reduced Media Independent Interface (RMII) – 2.5 MHz MII clock mode – 50 MHz RMII clock mode – Serial Management Interface (SMI) for rapid register access – Comprehensive status interrupt support • Carrier Sense Multiple Access / Collision Detection (CSMA/CD) media access control • Physical Layer Collision Avoidance (PLCA) – Allows for high bandwidth utilization by avoiding collisions on the physical layer – Burst mode for transmission of multiple packets for high packet rate latency-sensitive applications • Enhanced electromagnetic compatibility / electromagnetic interference (EMC/EMI) performance – Low RF emissions – Robust against injected currents and network cable shorts to ground or battery – Simple low cost analog front-end • Single 3.3V supply with integrated 1.8V regulator • Small footprint VQFN packaging with wettable flanks – LAN8670 32-pin (5 x 5 mm) – LAN8671 24-pin (4 x 4 mm) – LAN8672 36-pin (6 x 6 mm) • -40°C to +125°C extended temperature range • Microchip Functional Safety Ready Target Applications • Sensor/actuator networks operating at high bandwidth • Microphone networks delivering audio streams for beamforming, hands-free microphones, etc. • Backplane communication • Industrial control cabinets and machine control • Building automation © 2021 Microchip Technology Inc. and its subsidiaries Product Brief DS60001536E-page 1 |
