LIN standards and specifications

LIN (Local Interconnect Network) is a serial bus system. The LIN Consortium developed it originally. For the first time, the LIN specification was published as version 1.3. This version is still in use by some original equipment manufacturers (OEMs).

Version 2.0 was released in 2003. It is also still in use by many OEMs.

The LIN Consortium published the version 2.1 in 2006, which can be download here.

The LIN version 2.2A from 2010 was released after the LIN consortium was closed, but it is one of the most implemented version. You can download it here.

In parallel, the SAE organization developed the J2602 series; it was published in 2004 and updated in 2012. The SAE J2602 series is based on LIN version 2.0, implemented by several ASIC suppliers.

In the meantime, ISO has standardized the LIN communication system and related conformance test plans in the ISO 17987 series:

In the ISO 17987-7 conformance test plan are some inconsistencies with the ISO 17987-4 standard. They will be solved with the next systematic review of these documents. The conformity issues are described here and a proposal how to solve them is given, too.
