The Local Interconnect Network （LIN） is a serial communication protocol， designed to support automotive networks in conjunction with a 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 three 33662 versions are designed to operate at different maximum baud rates. The 33662LEF and 33662BLEF， and the 33662SEF and 33662BSEF， offer a normal baud rate （20 kbps）， and the 33662JEF and 33662BJEF， a slow baud rate （10 kbps）。 They integrate a fast baud rate （above 100 kbps）， as reported by the RXD pin for test and programming modes. They provide excellent EMC （Electromagnetic Compatibility） and Radiated Emission performance， ESD （Electrostatic Discharge） robustness， and safe behavior， in the event of a LIN bus short-to-ground， or a LIN bus leakage during lowpower mode. This device is powered by SMARTMOS technology.
