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 VIO 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 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.
