High-speed CAN/LIN fail-safe system basis chip
2. Features
2.1 General
s Contains a full set of CAN and LIN ECU functions:
x CAN transceiver and LIN transceiver
x Voltage regulator for the microcontroller (3.0 V, 3.3 V or 5.0 V)
x Separate voltage regulator for the CAN transceiver (5 V)
x Enhanced window watchdog with on-chip oscillator
x Serial Peripheral Interface (SPI) for the microcontroller
x ECU power management system
x Fully integrated autonomous fail-safe system
s Designed for automotive applications:
x Supports 14 V, 24 V and 42 V architectures
x Excellent ElectroMagnetic Compatibility (EMC) performance
x ± 8 kV ElectroStatic Discharge (ESD) protection Human Body Model (HBM) for off
board pins
x ± 60 V short-circuit proof CAN / LIN-bus pins
x Battery and CAN / LIN-bus pins are protected against transients in accordance with
ISO 7637
x Very low Sleep current
s Supports remote flash programming via the CAN-bus
s Small 8 mm × 11 mm HTSSOP32 package with low thermal resistance
2.2 CAN transceiver
s ISO 11898-2 and ISO 11898-5 compliant high-speed CAN transceiver
s Enhanced error signalling and reporting
s Dedicated low dropout voltage regulator for the CAN-bus:
x Independent from microcontroller supply
x Guarded by CAN-bus failure management
x Significantly improves EMC performance
s Partial networking option with global wake-up feature, allows selective CAN-bus
communication without waking up sleeping nodes
s Bus connections are truly floating when power is off
s SPLIT output pin for stabilizing the recessive bus level
2.3 LIN transceiver
s LIN 2.0 compliant LIN transceiver
s Enhanced error signalling and reporting
s Downward compatible with LIN 1.3 and the TJA1020
