EVPAA002K - Panasonic

EVPAA002K Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the EVPAA002K?
  Panasonic recommends a 4-layer PCB with a solid ground plane and a separate power plane for the VCC and GND pins. The layout should also minimize signal traces near the crystal oscillator pins to prevent noise interference.
• How do I ensure the crystal oscillator starts up reliably in my design?
  To ensure reliable startup, Panasonic recommends using a 10kΩ to 20kΩ pull-up resistor on the XTAL1 pin, and a 1kΩ to 2kΩ pull-down resistor on the XTAL2 pin. Additionally, the crystal oscillator circuit should be decoupled from the power supply using a 0.1uF capacitor.
• What is the maximum operating temperature range for the EVPAA002K?
  The EVPAA002K is rated for operation from -40°C to +125°C, but Panasonic recommends derating the operating temperature range to -20°C to +85°C for optimal performance and reliability.
• Can I use the EVPAA002K in a design that requires high humidity or moisture resistance?
  While the EVPAA002K is not specifically designed for high humidity or moisture resistance, Panasonic recommends using a conformal coating or potting compound to protect the device in such environments. However, the device's performance and reliability may be affected, and additional testing is recommended.
• What is the recommended storage condition for the EVPAA002K to prevent damage or degradation?
  Panasonic recommends storing the EVPAA002K in a dry, cool place with a relative humidity of 60% or less, and at a temperature range of -20°C to +30°C. The device should be stored in its original packaging or an equivalent ESD-protective package to prevent damage.
