LIN Physical Layer

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.

LINCELL

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 low-

power mode. This device is powered by SMARTMOS technology.
