TJA1054

Fault-tolerant CAN transceiver

Rev. 04 — 24 September 2009

Product data sheet

1. 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 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 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

TJA1053 are:

• 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_CC

• Support for easy system fault diagnosis

• Two-edge sensitive wake-up input signal via pin WAKE

2. Features

2.1 Optimized for in-car low-speed communication

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 and low power operating modes

I Fully integrated receiver ﬁlters

I Transmit Data (TxD) dominant time-out function

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 V_CC

I Automatic reset to differential mode if bus failure is removed

I Full wake-up capability during failure modes
