TJA1055T/3/1J

Optimized for in-car low-speed communication
 Pin-to-pin compatible with TJA1054 and TJA1054A
 Baud rate up to 125 kBd
 Up to 32 nodes can be connected
 Supports unshielded bus wires
 Very low ElectroMagnetic Emission (EME) due to built-in slope control function and a very good matching of the CANL and CANH bus outputs
 Very high ElectroMagnetic Immunity (EMI) in normal operating mode and in low power modes
 Fully integrated receiver filters
 Transmit Data (TxD) dominant time-out function
 High ESD robustness:
 8 kV Electrostatic Discharge (ESD) protection Human Body Model (HBM) for off-board pins
 6 kV Electrostatic Discharge (ESD) protection IEC 61000-4-2 for off-board pins
 Low-voltage microcontroller support
Bus failure management
 Supports single-wire transmission modes with ground offset voltages up to 1.5 V
 Automatic switching to single-wire mode in the event of bus failures, even when the CANH bus wire is short-circuited to VCC

 Automatic reset to differential mode if bus failure is removed
 Full wake-up capability during failure modes
Protections
 Bus pins short-circuit safe to battery and to ground
 Thermally protected
 Bus lines protected against transients in an automotive environment
 An unpowered node does not disturb the bus lines
 Microcontroller interface without reverse current paths, if unpowered
Support for low power modes
 Low current sleep mode and standby mode with wake-up via the bus lines
 Software accessible power-on reset flag
