Document Number: MC33399 Freescale Semiconductor Rev. 10.0, 4/2013 Technical Data Local Interconnect Network 33399 (LIN) Physical Interface 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 LIN PHYSICAL INTERFACE network, LIN enables cost-effective communication with sensors and actuators when all the features of CAN are not required. This device is powered by SMARTMOS technology. The 33399 is a physical layer component dedicated to automotive sub-bus applications. It offers communication speed from 1.0 kbps to 20 kbps, and up to 60 kbps for programming mode. It has two operating modes: Normal and Sleep. The 33399 supports LIN protocol specification 1.3.
