TJA1048

Dual high-speed CAN transceiver with Standby mode

Rev. 6 — 19 March 2018

Product data sheet

1. General description

The TJA1048 is a dual 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 the differential transmit and receive capability to (a microcontroller with) a CAN

protocol controller.

The TJA1048 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 TJA1040. It offers improved Electro Magnetic Compatibility (EMC)

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

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

• A very low-current Standby mode with bus wake-up capability on both channels

• Can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V

The TJA1048 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 TJA1048 an excellent choice for all types of HS-CAN networks

containing more than one HS-CAN interface that require a low-power mode with wake-up

capability via the CAN bus, especially for Body Control and Gateway units.

2. Features and benefits

2.1 General
