Product Introduction

Overview

The TJA1054AT/N,112 is a fault-tolerant CAN (Controller Area Network) transceiver produced by NXP USA Inc. This device serves as the interface between the CAN protocol controller and the physical bus wires in a CAN network. It is primarily designed for low-speed applications, up to 125 kBd, and is particularly suited for use in passenger cars. The TJA1054AT/N,112 is an improved version of the TJA1054, offering enhanced ElectroStatic Discharge (ESD) protection and other significant improvements over its predecessors, such as the PCA82C252 and TJA1053.

EME and EMIVery low ElectroMagnetic Emission (EME) and good ElectroMagnetic Immunity (EMI)

Key Features

  • Optimized for in-car low-speed communication.
  • Supports unshielded bus wires.
  • Very low ElectroMagnetic Emission (EME) due to built-in slope control function and good matching of 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.
  • Extended bus failure management including short-circuit of the CANH bus line to VCC.
  • Support for easy system fault diagnosis.
  • Two-edge sensitive wake-up input signal via pin WAKE.

Applications

The TJA1054AT/N,112 is primarily used in automotive applications, particularly in passenger cars, for low-speed CAN communication. It is suitable for systems that require robust and fault-tolerant communication over the CAN bus, such as vehicle control systems, diagnostic systems, and other automotive networks.
