W63AH2NBVABE Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended. Keep the signal traces short and away from noise sources. Refer to Winbond's application note AN-001 for more details.
  • Power up the VCCQ pin first, followed by the VCC pin. Ensure that the VCCQ pin reaches its minimum operating voltage before applying clock signals. Refer to the datasheet's power-up sequence diagram for more information.
  • The W63AH2NBVABE is rated for industrial temperature range, which is -40°C to 85°C. However, it's recommended to operate within -20°C to 70°C for optimal performance and reliability.
  • Use a reset IC with a voltage supervisor, such as the TLV7031, to ensure a clean and reliable reset signal. The reset signal should be asserted for at least 10ms to ensure a proper reset.
  • The clock signal should have a rise time of less than 1ns and a fall time of less than 1ns. The clock signal should also be terminated with a 50Ω resistor to prevent reflections.
