EP9307-IRZ datasheet by Cirrus Logic

EP9307-IRZ Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the EP9307-IRZ?
  The recommended power-up sequence is to apply VCC first, followed by VDD, and then VIO. This ensures proper device operation and prevents latch-up.
• How do I optimize the EP9307-IRZ's power consumption?
  To optimize power consumption, use the lowest possible clock frequency, disable unused peripherals, and use the power-down mode when the device is not in use. Additionally, consider using a lower voltage supply and optimizing the system's power management scheme.
• What is the maximum allowed capacitance for the crystal oscillator?
  The maximum allowed capacitance for the crystal oscillator is 20pF. Exceeding this value may affect the oscillator's stability and frequency accuracy.
• How do I ensure reliable operation of the EP9307-IRZ in high-temperature environments?
  To ensure reliable operation in high-temperature environments, ensure proper thermal design, use a heat sink if necessary, and follow the recommended operating conditions and thermal specifications outlined in the datasheet.
• What is the recommended layout and routing for the EP9307-IRZ's power and ground pins?
  The recommended layout and routing for the power and ground pins involves using wide, low-impedance traces, separating analog and digital power supplies, and minimizing inductive loops to reduce noise and ensure reliable operation.
