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 3Vto5V
The TJA1051 implements the CAN physical layer as defined in the current ISO11898
standard (ISO11898-2:2003, ISO11898-5:2007) and the pending updated version of
ISO 11898-2:2016. Pending the release of the updated version of ISO11898-2:2016
including CAN FD and SAE J2284-4/5, additional timing parameters defining loop delay
symmetry are specified. 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.
