General description
The TJA1055 is the interface between the protocol controller and the physical bus wires in
a Controller Area Network (CAN). It is primarily intended for low-speed applications up to
125 kBd in passenger cars. The device provides differential receive and transmit
capability but will switch to single-wire transmitter and/or receiver in error conditions. The
TJA1055 is the enhanced version of the TJA1054 and TJA1054A. TJA1055 has the same
functionality but in addition offering a number of improvements. The most important
improvements of the TJA1055 with respect to the TJA1054 and TJA1054A are:
Improved ElectroStatic Discharge (ESD) performance
Lower current consumption in sleep mode
Wake-up signalling on RXD and ERR without VCC active
3 V interfacing with microcontroller possible with TJA1055T/3

Features
2.1 Optimized for in-car low-speed communication
I Pin-to-pin compatible with TJA1054 and TJA1054A
I Baud rate up to 125 kBd
I Up to 32 nodes can be connected
I Supports unshielded bus wires
I Very low ElectroMagnetic Emission (EME) due to built-in slope control function and a
very good matching of the CANL and CANH bus outputs
I Very high ElectroMagnetic Immunity (EMI) in normal operating mode and in low power
modes
I Fully integrated receiver lters
I Transmit Data (TxD) dominant time-out function
I High ESD robustness:
N ±8 kV Electrostatic Discharge (ESD) protection Human Body Model (HBM) for
off-board pins
N ±6 kV Electrostatic Discharge (ESD) protection IEC 61000-4-2 for off-board pins
I Low-voltage microcontroller support
2.2 Bus failure management
I Supports single-wire transmission modes with ground offset voltages up to 1.5 V
I Automatic switching to single-wire mode in the event of bus failures, even when the
CANH bus wire is short-circuited to VCC
TJA1055
Enhanced fault-tolerant CAN transceiver
