High-speed CAN transceiver

Product data sheet

1. General description

The TJA1051 is a high-speed CAN transceiver that provides an interface between a

Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus.

The transceiver is designed for high-speed CAN applications in the automotive industry,

providing differential transmit and receive capability to (a microcontroller with) a CAN

protocol controller.

The TJA1051 belongs to the third generation of high-speed CAN transceivers from NXP

Semiconductors, offering significant improvements over first- and second-generation

devices such as the TJA1050. It offers improved ElectroMagnetic Compatibility (EMC)

and ElectroStatic Discharge (ESD) performance, and also features:

• Ideal passive behavior to the CAN bus when the supply voltage is off

• TJA1051T/3 and TJA1051TK/3 can be interfaced directly to microcontrollers with

supply voltages from 3 V to 5 V

The TJA1051 implements the CAN physical layer as defined in ISO 11898-2:2016 and

SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the

CAN FD fast phase at data rates up to 5 Mbit/s.

These features make the TJA1051 an excellent choice for all types of HS-CAN networks,

in nodes that do not require a standby mode with wake-up capability via the bus.

2. Features and benefits

2.1 General

 ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant

 Timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase

 Suitable for 12 V and 24 V systems

 Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)
