Network Controller & Processor ICs
NXP Semiconductors


The  TJA1055T/C,518  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 TJA1055T/C,518 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
TJA1055T/C,518  Features
• 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 ?lters
• Transmit Data (TxD) dominant time-out function
