TJA1057 High-speed CAN transceiver Rev. 6 24 August 2017 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 pin on the TJA1057GT(K)/3 variants allows for direct interfacing with 3.3 V and IO 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 input on TJA1057x/3 variants allows for direct interfacing with 3 V to 5 V IO microcontrollers. Variants without a V pin can interface with 3.3 V and 5 V-supplied IO 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 and non-V variants are available in SO8 and leadless HVSON8 (3.0 IO IO mm 3.0 mm) packages HVSON8 with improved Automated Optical Inspection (AOI) capability.TJA1057 NXP Semiconductors High-speed CAN transceiver 2.2 Predictable and fail-safe behavior Functional behavior predictable under all supply conditions Transceiver disengages from bus when not powered (zero load) Transmit Data (TXD) dominant time-out function Internal biasing of TXD and S input pins 2.3 Protection High ESD handling capability on the bus pins (8 kV IEC and HBM) Bus pins protected against transients in automotive environments Undervoltage detection on pins V and V CC IO Thermally protected 2.4 TJA1057 CAN FD (applicable to all product variants except TJA1057T) Timing guaranteed for data rates up to 5 Mbit/s Improved TXD to RXD propagation delay of 210 ns 3.
