Description / Abstract:
This document covers the requirements for SAE implementations
based on LIN 2.0. Requirements stated in this document will provide
a minimum standard level of performance to which all compatible
systems, design and development tools, software, ECUs and media
shall be designed. This will assure consistent and unambiguous
serial data communication among all connected devices regardless of
supplier.
This document may be referenced by any vehicle OEM component
technical specification that describes any given ECU in which the
single wire data link controller and physical layer interface is
located.
The intended audience includes, but is not limited to, ECU
suppliers, LIN controller suppliers, LIN transceiver suppliers,
component release engineers and vehicle system engineers.
Purpose
The goal of SAE J2602 is to improve the interoperability and
interchangeability of LIN devices within a network by resolving
those LIN 2.0 requirements that are ambiguous, conflicting, or
optional. Moreover, SAE J2602 provides additional requirements that
are not present in LIN 2.0 (e.g., fault tolerant operation, network
topology, etc.).
