TJA1057

High-speed CAN transceiver

Rev. 6 — 24 August 2017

Product data sheet

1. General description

The TJA1057 is part of the Mantis family of high-speed CAN transceivers. It 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 TJA1057 offers a feature set optimized for 12 V automotive applications, with

significant improvements over first- and second-generation CAN transceivers from NXP,

such as the TJA1050, and excellent ElectroMagnetic Compatibility (EMC) performance.

The TJA1057 also displays ideal passive behavior to the CAN bus when the supply

voltage is off.

A V_IOpin on the TJA1057GT(K)/3 variants allows for direct interfacing with 3.3 V and

5 V-supplied microcontrollers.

The TJA1057 implements the CAN physical layer as defined in ISO 11898-2:2016 and

SAE J2284-1 to SAE J2284-5. The TJA1057T is specified for data rates up to 1 Mbit/s.

Additional timing parameters defining loop delay symmetry are specified for the other

variants. This implementation enables reliable communication in the CAN FD fast phase

at data rates up to 5 Mbit/s.

These features make the TJA1057 an excellent choice for HS-CAN networks that only

require basic CAN functionality.

2. Features and benefits

2.1 General

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

 Optimized for use in 12 V automotive systems

 EMC performance satisfies 'Hardware Requirements for LIN, CAN and FlexRay

Interfaces in Automotive Applications’, Version 1.3, May 2012.

 V_IOinput on TJA1057x/3 variants allows for direct interfacing with 3 V to 5 V

microcontrollers. Variants without a V_IOpin can interface with 3.3 V and 5 V-supplied

microcontrollers, provided the microcontroller I/Os are 5 V tolerant.

 AEC-Q100 qualified

 Dark green product (halogen free and Restriction of Hazardous Substances (RoHS)

compliant)

 Both V_IOand non-V_IOvariants are available in SO8 and leadless HVSON8 (3.0

mm  3.0 mm) packages; HVSON8 with improved Automated Optical Inspection (AOI)

capability.
