+description: |
+ The ADIN1110 is a low power single port 10BASE-T1L MAC-
+ PHY designed for industrial Ethernet applications. It integrates
+ an Ethernet PHY core with a MAC and all the associated analog
+ circuitry, input and output clock buffering.
+
+ The ADIN2111 is a low power, low complexity, two-Ethernet ports
+ switch with integrated 10BASE-T1L PHYs and one serial peripheral
+ interface (SPI) port. The device is designed for industrial Ethernet
+ applications using low power constrained nodes and is compliant
+ with the IEEE 802.3cg-2019 Ethernet standard for long reach
+ 10 Mbps single pair Ethernet (SPE).
+
+ The device has a 4-wire SPI interface for communication
+ between the MAC and host processor.
