NXP TJA1057GTK | Demoboard FRDM-MCXN947

Description

he 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 electro magnetic compatibility (EMC) performance.The TJA1057 also displays ideal passive behavior to the CAN bus when the supply voltage is off.

Features

General FeaturesFully ISO 11898-2:2016, SAE J2284-1 to SAE J2284-5 and SAE J1939-14 compliantOptimized for use in 12 V automotive systemsLow Electromagnetic Emission (EME) and high Electromagnetic Immunity (EMI), according to proposed EMC Standards IEC 62228-3 and SAE J2962-2AEC-Q100 qualifiedDark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)Shorter propagation delay on the TJA1057B and TJA1057C variants supports larger network topologiesVariants with a VIO pin allow for direct interfacing with 3.3 V to 5 V microcontrollers. Variants without a VIO pin can interface with 3.3 V and 5 V-supplied microcontrollers, provided the microcontroller I/Os are 5 V tolerant.Predictable and Fail-safe BehaviorFunctional behavior predictable under all supply conditionsTransceiver disengages from bus when not powered (zero load)Transmit Data (TXD) dominant time-out functionInternal biasing of TXD and S input pinsProtectionHigh ESD handling capability on the bus pins (8 kV IEC and HBM)Bus pins protected against transients in automotive environmentsUndervoltage detection on pins VCC and VIOThermally protectedTJA1057GT(/3)/TJA1057GTK(/3)Timing guaranteed for data rates up to 5 Mbit/sImproved TXD to RXD propagation delay of 210 nsProduct Longevity ProgramThese products are included in the NXP Product Longevity Program ensuring a stable supply of products for your embedded designs.
