EN5335QI Frequently Asked Questions (FAQs)

  • Intel recommends a 4-layer PCB with a solid ground plane and thermal vias to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended for the top and bottom layers.
  • Intel recommends using a heat sink with a thermal interface material (TIM) and ensuring good airflow around the device. Additionally, consider using a thermal monitoring and control system to prevent overheating.
  • The EN5335QI requires a single 3.3V power supply with a minimum of 1.5A current capability. The power supply should be decoupled with 10uF and 0.1uF capacitors to ensure stable operation.
  • The EN5335QI has multiple power modes. Configure the device to use the lowest power mode suitable for your application. Use the Intel-provided power management software development kit (SDK) to optimize power consumption.
  • The EN5335QI requires a 25MHz clock signal with a 3.3V amplitude. The reset signal should be asserted for at least 10ms during power-up and have a 10kΩ pull-up resistor to ensure proper reset operation.
