TJA1054AT Datasheet

Network Controller & Processor ICs


The TJA1054AT 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 TJA1054AT is the ElectroStatic Discharge (ESD) improved version of the TJA1054.The TJA1054AT is, as the TJA1054T, pin and downwards compatible with the PCA82C252T and the TJA1053T. This means that these two devices can be replaced by the TJA1054AT or the TJA1054T with retention of all functions. TJA1054AT Features • 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• Good ElectroMagnetic Immunity (EMI) in normal operating mode and in low power modes• Fully integrated receiver filters• Transmit Data (TxD) dominant time-out function
