TJA1462 CAN FD signal improvement transceiver with Standby mode Rev. 2 15 October 2021 Product data sheet 1 General description The TJA1462 is a member of the TJA146x family of transceivers that provide an interface between a Controller Area Network (CAN) or CAN FD (Flexible Data rate) protocol controller and the physical two-wire CAN bus. TJA146x transceivers implement the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5, and are fully interoperable with high-speed Classical CAN and CAN FD transceivers. The TJA1462 includes CAN Signal Improvement Capability (SIC), as defined in CiA 601-4:2019. CAN signal improvement significantly reduces signal ringing in a network, allowing reliable CAN FD communication to function in larger topologies. In addition, the TJA1462 features a much tighter bit timing symmetry performance to enable CAN FD communication up to 8 Mbit/s. The TJA1462 is intended as a simple replacement for high-speed Classical CAN and CAN FD transceivers, such as the TJA1042 or TJA1044GT from NXP. It offers pin compatibility and is designed to avoid changes to hardware and software design, allowing the TJA1462 to be easily retrofitted to existing applications. An AEC-Q100 Grade 0 variant, the TJR1462, is available for high temperature applications, supporting operation at 150 C ambient temperature. 1.1 TJA1462 variants The TJA1462 comes in two variants, each available in an SO8 or HVSON8 package: The TJA1462A is a high-speed CAN transceiver with Normal and Standby modes and a VIO supply pin. The VIO pin allows for direct interfacing with 3.3 V- and 5 V-supplied microcontrollers. The TJA1462B is a high-speed CAN transceiver with Normal and Standby modes. 2 Features and benefits 2.1 General ISO 11898-2:2016, SAE J2284-1 to SAE J2284-5 and SAE J1939-14 compliant Implements CAN Signal Improvement Capability as defined in CiA 601-4:2019 to significantly reduce signal ringing effects in a network Much tighter bit timing symmetry performance allowing more time to reduce signal ringing Low Electromagnetic Emission (EME) and high Electromagnetic Immunity (EMI) Qualified according to AEC-Q100 Grade 1 TJA1462A only: VIO input for interfacing with 3.3 V to 5 V microcontrollers All variants are available in SO8 and leadless HVSON8 (3.0 mm x 3.0 mm) packages HVSON8 with improved Automated Optical Inspection (AOI) capability.NXP Semiconductors TJA1462 CAN FD signal improvement transceiver with Standby mode Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant) 2.2 Predictable and fail-safe behavior Undervoltage detection with defined handling on all supply pins Full functionality guaranteed from the undervoltage detection thresholds up to the maximum limiting voltage values Defined behavior below the undervoltage detection thresholds Transceiver disengages from the bus (high-ohmic) when the supply voltage drops below the Off mode threshold Internal biasing of TXD and mode selection input pins, to enable defined fail-safe behavior 2.3 Low-power management Very low-current Standby mode with host and bus wake-up capability TJA1462A only: CAN wake-up receiver powered by V allowing V to be shut down IO CC CAN wake-up pattern filter time of 0.5 s to 1.8 s, meeting Classical CAN and CAN FD requirements 2.4 Protection High ESD handling capability on the bus pins (6 kV IEC and 8 kV HBM) Bus pins protected against transients in automotive environments Transmit Data (TXD) dominant time-out function Thermally protected TJA1462 All information provided in this document is subject to legal disclaimers.
