TJA1055

www.DataSheet4U.com TJA1055 Enhanced fault-tolerant CAN transceiver Rev. 02 — 30 October 2006 Preliminary data sheet 1. 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 2. Features 2.1 Optimized for in-car low-speed communication I I I I I I I I I 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 filters Transmit Data (TxD) dominant time-out function High ESD robustness N ±8...
