LIN 2.1 / SAEJ2602-2 Dual LIN
Physical Layer
33663
The 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 33663 product line integrates two physical layer LIN bus
dedicated to automotive LIN sub-bus applications. The MC33663LEF
and MC33663SEF devices offer normal baud rate (20 kbps) and the
MC33663JEF slow baud rate (10 kbps). Both devices integrate fast
baud rate (above 100 kbps) for test and programming modes. They
present excellent electromagnetic compatibility (EMC) and radiated
emission performance, electrostatic discharge (ESD) robustness and
safe behavior, in the event of LIN bus short-to-ground or LIN bus
leakage during low-power mode.
