Key Differentiators
- AEC-Q100 automotive qualification (vs TCAN4550RGYR)
- Reel packaging for automated assembly (vs TCAN4550RGYTQ1)
- Integrated CAN FD controller + transceiver in VQFN-20 (vs NXP TJA1145AT/FD)
Design Notes
The VQFN-20 package features an exposed thermal pad. For reliable automotive operation, solder the thermal pad to a copper pour on the PCB and provide multiple thermal vias to the ground plane. This ensures heat dissipation from the internal LDO and CAN transceiver, especially at high data rates (8 Mbps) and elevated ambient temperatures.
Place a 100 nF decoupling capacitor close to the VCC and VIO pins, and a 10 uF capacitor near the LDO_IN pin. Ensure the SPI traces are kept short and shielded from the CAN bus lines (CANH/CANL) to minimize EMI coupling. The CAN bus lines should be routed as a differential pair with series termination resistors (typically 60 ohms) for signal integrity.
Do not enable the CAN transceiver before configuring the SPI registers, as an unconfigured device may cause bus errors. Ensure the LDO output capacitor meets the stability requirements specified in the datasheet (value not provided). The watchdog timer should be serviced periodically by the host MCU; failure to do so will reset the device, possibly interrupting communication.
