●Overview
●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.
