The ADIN1111 is an ultra low power, single port, 10BASE-T1L transceiver design for industrial Ethernet applications and is compliant with the IEEE^® 802.3cg-2019™ Ethernet standard for long reach, 10 Mbps single pair Ethernet (SPE). Featuring an integrated media access control (MAC) interface, the ADIN1111 enables direct connectivity with a variety of host controllers via a serial peripheral interface (SPI). This SPI enables the use of lower power processors without an integrated MAC, which provides for the lowest overall system level power consumption. The ADIN1111 is designed for edge node sensors and field instruments deployed in building, factor, and process automation.

The device operates from a single power supply rail of 1.8 V or 3.3 V, supporting both 1.0 V and 2.4 V. The internal hybrid and termination resistors allow the ADIN1111 to connect directly to the MDI interface.

The ADIN1111 has an integrated voltage supply monitoring and power-on reset (POR) circuitry to improve system level robustness and has a 4-wire SPI for communication between the MAC interface and host processor.

The ADIN1111 is available in a 32-lead, 5 mm × 5 mm lead frame chip scale package [LFCSP].
