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 3 V to 5 V
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.
Features and benefits
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)
✦ VIO input on TJA1042T/3 and TJA1042TK/3 allows for direct interfacing with 3 V to 5 V microcontrollers
✦ SPLIT voltage output on TJA1042T for stabilizing the recessive bus level
✦ Available in SO8 package and leadless HVSON8 package (3.0 mm X 3.0 mm) with improved Automated Optical Inspection (AOI) capability
✦ Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)
✦ AEC-Q100 qualified
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 VCC and VIO
Protections
✦ High ESD handling capability on the bus pins (±8 kV)
✦ High voltage robustness on CAN pins (±58 V)
✦ Bus pins protected against transients in automotive environments Thermally protected
