sources are switched off and pull-ups are switched on 3.5 The last node will accept the address contained in the LIN configuration message This technique is covered by the patents EP 1490772 B1 and US 7091876. LIN advantages Easy to use Components available Cheaper than CAN and other communications buses Harness reduction More reliable vehicles Extension easy to implement. No protocol license fee required LIN is not a full replacement of the CAN bus. But the LIN bus is a good alternative wherever low costs are essential and speed/bandwidth is not important. Typically, it is used within sub-systems that are not critical to vehicle performance or safety - some examples are given below. Applications Addressing Addressing in LIN is achieved with a NAD (Node ADdress) that is part of the PID (protected identifier). NAD values are on 7bits, so in the range 1 to 127 (0x7F) and it is a composition of supplier ID, function ID and variant ID. You can obtain a supplier ID by contacting CAN in Automation that is the authority responsible for the assignment of such identifiers.
