TJA1057

High-speed CAN transceiver

Rev. 5 — 23 May 2016

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 the current

ISO11898-2:2003 standard and the pending updated version of ISO11898-2:2016. The

TJA1057T variant is specified for data rates up to 1 Mbit/s. Pending the release of

ISO11898-2:2016 including CAN FD and SAE-J2284-4/5, additional timing parameters

are specified for the TJA1057GT(/3) and TJA1057GTK(/3) 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 11898-2:2003 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_IOoption allows for direct interfacing with 3.3 V and 5 V-supplied microcontrollers

 Non-V_IOvariants 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)

 Available in SO8 package and leadless HVSON8 package (3.0 mm  3.0 mm) with

improved Automated Optical Inspection (AOI) capability
