title: Microchip LAN8650/1 10BASE-T1S MACPHY Ethernet Controllers

maintainers:
  - Parthiban Veerasooran <parthiban.veerasooran@microchip.com>

description:
  The LAN8650/1 combines a Media Access Controller (MAC) and an Ethernet
  PHY to enable 10BASE‑T1S networks. The Ethernet Media Access Controller
  (MAC) module implements a 10 Mbps half duplex Ethernet MAC, compatible
  with the IEEE 802.3 standard and a 10BASE-T1S physical layer transceiver
  integrated into the LAN8650/1. The communication between the Host and
  the MAC-PHY is specified in the OPEN Alliance 10BASE-T1x MACPHY Serial
  Interface (TC6).
