The recommended power-on sequence is to apply the power supplies in the following order: VDDA, VDD, and finally VIO. This ensures proper device operation and prevents latch-up.
To optimize power consumption, use the lowest possible clock frequency, disable unused peripherals, and use the power-down modes (e.g., idle, standby, or shutdown) when the device is not in use.
The maximum allowed capacitance for the crystal oscillator is 20 pF. Exceeding this value may affect the oscillator's performance and stability.
Yes, the AM3703CUS can operate with a 3.3V power supply. However, ensure that the input voltage is within the recommended range (1.8V to 3.6V) and that the device is properly decoupled.
To troubleshoot USB issues, check the USB clock frequency, ensure proper signal termination, and verify that the USB pins are not overloaded. Also, review the USB protocol and device configuration to ensure compliance with the USB specification.
