TJA1463AT/0Z - 8Mbit/s CAN SIC Transceiver | NXP
N.º de pieza: TJA1463AT/0Z ✓ ActivoTJA1463AT/0Z Descripción general
A CAN transceiver is the physical-layer interface between a controller and a CAN bus. It converts logic-level TXD and RXD signals into balanced differential CANH and CANL bus signals, while also supporting bus-fault detection, error indication, standby control, and low-power operation. The TJA1463 belongs to the interface IC hierarchy, connecting automotive CAN controllers to CAN, CAN FD, and CAN FD with CAN Signal Improvement Capability networks.
The TJA1463 implements CAN Signal Improvement Capability according to ISO 11898-2:2024 parameter set C. This capability reduces signal ringing, improves communication reliability in larger network topologies, and provides tighter bit-timing symmetry than conventional high-speed CAN transceivers. Its 8 Mbit/s CAN FD capability makes it suitable for distributed automotive control systems that carry payloads faster than Classical CAN.
The TJA1463 is designed as a straightforward replacement for high-speed Classical CAN and CAN FD transceivers such as the TJA1043 and TJA1443. NXP identifies pin compatibility and retrofit capability as key benefits, allowing existing hardware and software architectures to be retained. A VIO-level interface supports flexible digital-voltage interfacing, while STB provides standby control and Sleep mode reduces power demand when the network is inactive.
Typical uses include electric-vehicle powertrain controllers, body and comfort modules, battery-management systems, charging interfaces, gateway controllers, and other ECUs connected to 500-kbit/s or faster CAN FD backbones. The combination of 8 Mbit/s operation, ISO 11898-2:2024 SIC behavior, and a 14-pin SO footprint supports both new designs and targeted network upgrades.
Designers should follow the manufacturer’s recommended CAN bus decoupling and connector-layout guidance, provide the specified VCC and VIO levels, and validate termination, stub length, and loop delay in the complete network. Standby and sleep-state transitions should also be checked against the ECU wake-up strategy to prevent unwanted bus-state transitions.
This product overview combines the manufacturer’s CAN SIC capabilities, retrofit positioning, package details, and search-driven engineering questions with practical guidance for firmware integration, network layout, and drop-in replacement decisions.

Aplicaciones típicas
TJA1463AT/0Z es adecuado para 6 aplicacións: Electric Vehicle Powertrain Controller, Body and Comfort Module, Battery Management System, Vehicle Charging Interface, Automotive Gateway Controller, Industrial CAN FD Control Module.
Electric Vehicle Powertrain Controller
The TJA1463AT/0Z fits an electric-vehicle powertrain ECU that exchanges torque, inverter, and battery-status information over a CAN FD backbone. Its 8 Mbit/s CAN FD rate supports faster payload transfer, while CAN SIC reduces signal ringing and improves bit-timing symmetry in larger vehicle networks. The 14-pin SO package simplifies retrofit into existing NXP transceiver layouts. Confirm mode-control polarity, bus timing, and sleep behavior during integration with the vehicle controller.
Recomendado
Body and Comfort Module
A body-control module can use the TJA1463AT/0Z for CAN FD communication with door, lighting, climate, and seating controllers. The transceiver’s ISO 11898-2:2024 CAN SIC behavior helps preserve reliable communication when the vehicle contains longer branches or additional bus stubs. Its 4.5 V to 5.5 V operating range, -40 C to +150 C rating, and AEC-Q100 listing fit harsh automotive environments. Firmware must configure bit timing consistently across all nodes.
Recomendado
Battery Management System
The TJA1463AT/0Z is suitable for a battery-management unit that reports cell measurements, pack state, and thermal information through an automotive CAN FD network. The 8 Mbit/s capability reduces transfer time for larger diagnostic and diagnostic-adjacent payloads, while CAN SIC limits ringing in complex harnesses. The VIO, STB, and ERR functions support controller interfacing, standby control, and fault indication. Validate wake-up behavior so pack monitoring remains responsive during low-power periods.
Recomendado
Vehicle Charging Interface
An onboard charger or charging-interface controller can employ the TJA1463AT/0Z to communicate status and control data over CAN FD. CAN SIC is valuable in vehicle architectures where bus length, branching, or connector transitions might otherwise create reflections. The device supports communication up to 8 Mbit/s and operates across the automotive temperature range. Designers should use the manufacturer’s recommended transceiver grounding, VCC decoupling, and CAN bus layout to preserve signal quality and EMC performance.
Recomendado
Automotive Gateway Controller
The TJA1463AT/0Z suits an automotive gateway that links CAN FD domains carrying body, chassis, and powertrain data. Its 8 Mbit/s operation supports efficient gateway traffic, while improved bit-timing symmetry makes the link less sensitive to timing spread among communicating nodes. CAN SIC reduces ringing in larger topologies, complementing the gateway’s role as a network aggregation point. Use identical bit-timing concepts across connected nodes and verify any sleep-mode wake-up path through the gateway.
Recomendado
Industrial CAN FD Control Module
The TJA1463AT/0Z can also be evaluated for industrial CAN FD equipment that benefits from the signal-ringing reduction provided by CAN SIC. Its 8 Mbit/s data rate supports high-throughput machine control, remote I/O, and test systems, while the 14-pin SO package facilitates board replacement of compatible NXP designs. Industrial implementations still require EMC, surge, grounding, and temperature validation, and firmware should use the manufacturer-defined standby and sleep-state transitions.

- Improves timing symmetry for multi-node CAN FD networks (frente a TJA1443AT/0Z)
Notas de diseño
Place the transceiver, its CANH and CANL connection, and the required bus-side components according to the manufacturer’s recommended PCB layout. Keep the VCC and VIO decoupling paths short, preserve a continuous return path beneath the signal routes, and avoid routing CAN bus traces over discontinuous ground planes. These practices reduce radiated emissions and susceptibility to external noise.
Keep the CANH and CANL route geometry as symmetric as practical and avoid adding unnecessary branches between the transceiver and the bus connectors. Long stubs can create reflections that consume timing margin even when CAN SIC is active. Review connector transitions, cable splits, and node placement during network simulation, then confirm the selected bit-timing configuration across every ECU on the bus.
Do not assume that Sleep mode can be entered without coordinating the controller and wake-up hardware. STB polarity, controller state, bus activity, and the device’s internal sleep-entry conditions must be checked against the NXP datasheet. Also verify that firmware handles ERR events and recovery transitions correctly; a physically compatible transceiver does not guarantee that two devices use identical fault-management policy.
Información de cumplimiento
The component is listed for automotive applications with AEC-Q100 qualification. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status require confirmation from current NXP declarations.
