TJA1462ATK-S1Z - CAN SIC Transceiver 8Mbit/s | NXP | Automotive
MPN: TJA1462ATK-S1Z ✓ Hoạt độngTJA1462ATK-S1Z Tóm tắt
A CAN SIC transceiver is a specialized CAN physical-layer device that conditions the bus signal to suppress the resonance and ringing artifacts that occur at higher CAN FD data rates. By smoothing the recessive-to-dominant and dominant-to-recessive edges, the TJA1462 allows networks to operate reliably at 5 Mbit/s and above, extending the usable bandwidth of CAN FD without requiring twisted-pair cable changes or extra bus nodes. The part family belongs to NXP's TJA146x automotive transceiver family, positioned between classical High-Speed CAN transceivers and emerging CAN XL physical-layer devices.
Key features include a separate VIO supply pin for logic-level translation to 1.8V, 3.3V, or 5V microcontrollers without level shifters, ultra-low quiescent current consumption in Standby mode for battery-powered ECUs, bus dominant time-out protection, and under-voltage detection on both VCC and VIO rails. The HVSON-8 (3.0 mm × 3.0 mm) package with an exposed thermal pad enables reflow-compatible SMT assembly and provides a low thermal resistance path for dissipating bus-fault energy. AEC-Q100 Grade 1 qualification and an extended -40 °C to +125 °C operating temperature range make the device suitable for under-hood and body-control automotive applications.
Typical applications include automotive body control modules, gateway ECUs bridging CAN FD powertrain domains, ADAS sensor nodes, and industrial CAN FD backbones. The Standby mode with wake-up via bus activity allows the part to be used in always-on networks where quiescent current budget is critical.
When designing with the TJA1462ATK-S1Z, place the VCC and VIO decoupling capacitors within 2 mm of their respective pins and connect the exposed pad to a continuous ground copper pour for thermal dissipation and EMC performance. The STB (Standby) pin should be driven by a GPIO capable of retaining state across MCU reset to avoid unintended bus state changes during boot.

Ứng dụng tiêu biểu
TJA1462ATK-S1Z phù hợp cho 6 Áp dụngs: Automotive Body Control Module (BCM), CAN FD Gateway ECU, ADAS Sensor Node, Industrial CAN FD Backbone, Electric Vehicle Battery Management System (BMS), Agricultural and Off-Highway Vehicle Network.
Automotive Body Control Module (BCM)
The TJA1462ATK-S1Z fits automotive Body Control Modules because it is AEC-Q100 Grade 1 qualified and supports CAN FD at 5 Mbit/s over standard automotive twisted-pair wiring harnesses. Its Standby mode with bus wake-up capability suits always-connected BCMs that must remain on the bus while the vehicle is parked without draining the 12 V battery, and the VIO pin lets the BCM's 3.3 V MCU interface directly. In a BCM the TJA1462 links window, door, mirror, and lighting ECUs at high speed while coexisting with legacy 500 kbit/s CAN nodes on the same bus.
Được đề xuất
CAN FD Gateway ECU
The TJA1462ATK-S1Z is well-suited to central gateway ECUs that interconnect powertrain, chassis, and body CAN FD domains at 5 Mbit/s. Its CAN SIC capability reduces bus ringing across long harness runs between ECUs located in different vehicle zones, eliminating the need for special low-loss cable or star-stub topology. The 8 Mbit/s ceiling provides overhead as next-generation CAN FD data rates climb, and the small 3 mm × 3 mm HVSON-8 footprint fits densely populated gateway PCBs alongside Ethernet PHYs and switch ASICs.
Được đề xuất
ADAS Sensor Node
The TJA1462ATK-S1Z's 8 Mbit/s CAN SIC performance and -40 °C to +125 °C automotive temperature range make it appropriate for ADAS sensor nodes such as radar, lidar, and surround-view camera ECUs that stream high-bandwidth sensor data over CAN FD. SIC suppresses the bus ringing that would otherwise corrupt high-speed sensor frames, and the device's AEC-Q100 Grade 1 qualification ensures reliability in the thermal and vibration environment behind the front bumper. VIO logic-level translation allows the sensor MCU to operate at 1.8 V for low power consumption while the CAN bus stays at 5 V.
Được đề xuất
Industrial CAN FD Backbone
The TJA1462ATK-S1Z can be used in industrial CAN FD backbones such as factory-automation cells, robotics controllers, and building automation networks where 5 Mbit/s data rates reduce cycle times compared to classical 1 Mbit/s CAN. The VIO pin accepts 1.8 V to 5 V, simplifying integration with modern low-voltage industrial MCUs, and the wide operating temperature range suits outdoor and factory-floor thermal envelopes. SIC operation also improves signal integrity across long industrial cable runs where reflections degrade classical CAN FD.
Được đề xuất
Electric Vehicle Battery Management System (BMS)
The TJA1462ATK-S1Z fits EV Battery Management Systems that communicate cell-voltage and temperature data to the Battery Junction Box over CAN FD. Its ultra-low Standby current preserves EV auxiliary battery capacity during parking, and the SIC capability enables 5 Mbit/s data rates so large cell arrays can stream telemetry within tight BMS reporting windows. The HVSON-8 footprint with exposed thermal pad dissipates bus-fault energy cleanly, important in the high-voltage environment adjacent to traction battery packs.
Được đề xuất
Agricultural and Off-Highway Vehicle Network
The TJA1462ATK-S1Z's AEC-Q100 qualification and robust CAN SIC performance suit agricultural tractors, construction equipment, and off-highway vehicles that use long CAN FD backbones across exposed harnesses subject to moisture and EMI. SIC ringing suppression ensures reliable 5 Mbit/s communication across multi-meter cable runs, and the extended -40 °C to +125 °C range covers cab and engine-bay mounting. The VIO pin simplifies interfacing with the 3.3 V MCUs commonly used in modern agricultural controllers.

Ghi chú thiết kế
Place the VCC and VIO decoupling capacitors within 2 mm of their respective pins, using short, wide traces to minimize parasitic inductance. The exposed thermal pad (EP) on the HVSON-8 package must be soldered to a continuous ground copper pour of at least 25 mm² to meet the datasheet thermal resistance and to provide a low-impedance return path for bus common-mode currents during ESD events.
Route the CANH and CANL traces as a differential pair with 100 Ω differential impedance, keeping the pair length matched within 5 mm to avoid skew-induced ringing. Place a split-terminator network (two 60 Ω resistors in series with a 4.7 nF capacitor to ground at the midpoint) close to the bus pins for proper SIC edge shaping. Avoid routing the CAN pair near noisy switching traces; keep at least 3 mm clearance from clock lines and DC-DC switch nodes.
Do not leave the STB pin floating - tie it to GND through a 100 kΩ pull-down if the host MCU does not actively drive it, to avoid unintended Standby entry at power-up. Verify that VIO is powered before or simultaneously with VCC to prevent latch-up at the logic-level translation block. In designs migrating from a non-SIC CAN FD transceiver, ensure the bus topology still meets ISO 11898-2:2024 maximum stub length and node count limits for SIC operation.
The TJA1462ATK-S1Z's SIC function actively damps the bus resonance that causes signal ringing at CAN FD bit rates above 2 Mbit/s. For maximum benefit, use the recommended split termination with a common-mode choke on long cable runs (>3 m). At the highest 8 Mbit/s data rate, scope-probe the CANH-CANL differential signal and verify that the recessive-to-dominant edge settles within one bit time; if not, check for excessive stub length or missing termination.
