TJA1057T,118

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.
Variants with a VIO pin can be interfaced directly with microcontrollers with supply
voltages from 3.3 V to 5 V.
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. The TJA1057B and TJA1057C feature shorter propagation
delay, supporting larger network topologies.
These features make the TJA1057 an excellent choice for HS-CAN networks that only
require basic CAN functionality.
