TJA1042 High-speed CAN transceiver with Standby mode Rev. 10 24 November 2017 Product data sheet 1. General description The TJA1042 high-speed CAN transceiver 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 TJA1042 belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over first- and second-generation devices such as the TJA1040. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features: Ideal passive behavior to the CAN bus when the supply voltage is off A very low-current Standby mode with bus wake-up capability TJA1042T/3 and TJA1042TK/3 can be interfaced directly to microcontrollers with supply voltages from 3Vto5V The TJA1042 implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s. These features make the TJA1042 an excellent choice for all types of HS-CAN networks, in nodes that require a low-power mode with wake-up capability via the CAN bus. 2. Features and benefits 2.1 General ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant Timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase Suitable for 12 V and 24 V systems Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI) V input on TJA1042T/3 and TJA1042TK/3 allows for direct interfacing with 3 V to 5 V IO microcontrollers SPLIT voltage output on TJA1042T for stabilizing the recessive bus level Available in SO8 package and leadless HVSON8 package (3.0 mm 3.0 mm) with improved Automated Optical Inspection (AOI) capability Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant) AEC-Q100 qualifiedTJA1042 NXP Semiconductors High-speed CAN transceiver with Standby mode 2.2 Predictable and fail-safe behavior Very low-current Standby mode with host and bus wake-up capability Functional behavior predictable under all supply conditions Transceiver disengages from the bus when not powered up (zero load) Transmit Data (TXD) dominant time-out function Bus-dominant time-out function in Standby mode Undervoltage detection on pins V and V CC IO 2.3 Protections High ESD handling capability on the bus pins ( 8kV) High voltage robustness on CAN pins ( 58 V) Bus pins protected against transients in automotive environments Thermally protected 3.
