Notes
- Pin 5 (VIO): The TCAN1044ADRBRQ1 variant includes the VIO supply pin (indicated by the "V" suffix). This pin is not present in NC-suffix variants.
- Thermal Pad: The VDFN package includes an exposed thermal pad on the bottom. This pad must be connected to ground via multiple vias for proper heat dissipation.
- Pull-ups: TXD (pin 1) and STB (pin 8) have integrated pull-up resistors.
