Analog Devices ADIN1110 and ADIN2111 10BASE-T1L Single-Pair Ethernet Controllers

Single-pair Ethernet MAC-PHY chips from Analog Devices that connect a microcontroller or small embedded system over SPI to a 10BASE-T1L network. They target industrial automation, building controls, and process instrumentation, where 10BASE-T1L runs Ethernet over a single twisted pair for up to a kilometre, often replacing legacy fieldbuses.

recommendation

It should stay because the hardware is current: Analog Devices still markets both the ADIN1110 and ADIN2111 as recommended for new designs in 2025, and the kernel driver is actively maintained, with a fix landing in netdev in early 2026 and getting backported to stable. Deployments are niche (industrial single-pair Ethernet) but the ecosystem is alive and growing.

sources

  1. lore.kernel.org

    Netdev still carried a driver-specific adin1110 fix in February 2026, indicating ongoing upstream maintenance rather than obsolescence.

  2. lore.kernel.org

    That adin1110 fix was backported to stable, showing the driver is relevant enough for supported stable kernels.

  3. analog.com

    Analog Devices listed ADIN1110 as 'RECOMMENDED FOR NEW DESIGNS' and offered sample/buy options, evidence the hardware was still sold new beyond 2025.

  4. analog.com

    Analog Devices listed ADIN2111 as 'RECOMMENDED FOR NEW DESIGNS' with current pricing/evaluation material, supporting continued availability and industrial use.

codex reasoning notes (technical)

Identified locally via shell (`rg`, `sed`) as the ADIN1110/ADIN2111 SPI MAC-PHY driver. Lore evidence came from `lore_file_timeline` and `lore_activity`: recent 2026 netdev and stable touches show ongoing fixes/backports; no removal signal was found in the lore queries attempted. Product availability came from web search on analog.com product pages, both marked recommended for new designs with active buy/eval collateral. This looks like niche but current industrial single-pair Ethernet hardware, so keep rather than deprecate.
