Product Summary
Freescale SemiconductorAdvance InformationLIN 2.1 / SAEJ2602-2 Dual LINPhysical LayerThe local interconnect network (LIN) is a serial communicationprotocol designed to support automotive networks in conjunction withcontroller area network (CAN). As the lowest level of a hierarchicalnetwork, LIN enables cost-effective communication with sensors andactuators when all the features of CAN are not required.The 33663 product line integrates two physical layer LIN busdedicated to automotive LIN sub-bus applications. The MC33663LEFand MC33663SEF devices offer normal baud rate (20 kbps) and theMC33663JEF slow baud rate (10 kbps). Both devices integrate fastbaud rate (above 100 kbps) for test and programming modes. Theypresent excellent electromagnetic compatibility (EMC) and radiatedemission performance, electrostatic discharge (ESD) robustness andsafe behavior, in the event of LIN bus short-to-ground or LIN busleakage during low-power mode
