TJA1054T
TJA1054U
Baud rate up to 125 kBaud
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
Good ElectroMagnetic Immunity (EMI) in normal
operating mode and in low power modes
Fully integrated receiver filters
Transmit Data (TxD) dominant time-out function.
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 V
Automatic reset to differential mode if bus failure is
removed
Full wake-up capability during failure modes.
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.
Low current sleep and standby mode with wake-up via
the bus lines
Power-on reset flag on the output.

DESCRIPTION
GENERAL DESCRIPTION
The TJA1054 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 kBaud 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 TJA1054T is pin and downwards compatible with the
PCA82C252T and the TJA1053T. This means that these
two devices can be replaced by the TJA1054T with
retention of all functions.
The most important improvements of the TJA1054 with
respect to the PCA82C252 and the TJA1053 are:
PACKAGE
Very low EME due to a very good matching of the CANL
and CANH output signals
Good EMI, especially in low power modes
Full wake-up capability during bus failures
Extended bus failure management including
short-circuit of the CANH bus line to V
Support for easy system fault diagnosis
Two-edge sensitive wake-up input signal via pin WAKE.
