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.
