Advance Information  
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.  
DUAL LIN TRANSCEIVER  
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.
