ADIN1111: Robust, industrial, low-power 10BASE-T1L Ethernet MAC-PHY
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).
The SPI on the ADIN1111 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].
