MC33399

Freescale Semiconductor Technical Data Document Number: MC33399 Rev. 10.0, 4/2013 Local Interconnect Network (LIN) Physical Interface 33399 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. 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. Features Nominal operation from VSUP 7.0 to 18 V DC, functional up to 27 V DC battery voltage and capable of handling 40 V during load dump Active bus waveshaping to minimize radiated emission ±5.0 kV ESD on LIN Bus Pin, ±4.0 kV ESD on other pins 30 k internal pull-up resistor Ground shift operation and ground disconnection Fail-safe at module level An unpowered node does not disturb the network 20 µA in Sleep mode Wake-up capability from LIN Bus, MCU command and dedicated high voltage wake-up input (interface to external switch) Interface to MCU with CMOS compatible I/O pins Control of external voltage regulator LIN PHYSICAL INTERFACE EF SUFFIX (PB-FREE) 98ASB42564B 8 PIN SOI...
