description: |
The ADIN1140 (also called AD3306) is a low power single port
10BASE-T1S MAC-PHY. It integrates an Ethernet PHY with a MAC
and all the associated analog circuitry.
The device tries to implement the Open Alliance TC6 10BASE-T1x MAC-PHY
Serial Interface specification and is compliant with the
IEEE 802.3cg-2019 Ethernet standard for 10 Mbps single pair
Ethernet (SPE). The device has a 4-wire SPI interface for
communication between the MAC and host processor.
