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
IO
pin 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
IO
input on TJA1057x/3 variants allows for direct interfacing with 3 V to 5 V
microcontrollers. Variants without a V
IO
pin 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
IO
and non-V
IO
variants are available in SO8 and leadless HVSON8 (3.0
mm 3.0 mm) packages; HVSON8 with improved Automated Optical Inspection (AOI)
capability.
