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.
