Local Interconnect Network
(LIN) Physical Interface
33399
Local Interconnect Network (LIN) is a serial communication
protocol designed to support automotive networks in conjunction with
Controller Area Network (CAN). As the lowest level of a hierarchical
network, LIN enables cost-effective communication with sensors and
actuators when all the features of CAN are not required.
The 33399 is a Physical Layer component dedicated to automotive
sub-bus applications. It offers speed communication from 1.0 kbps to
20 kbps, and up to 60 kbps for Programming Mode. It has two
operating modes: Normal and Sleep.
The 33399 supports LIN Protocol Specification 1.3.
