AM1805AQ Details

The recommended power-on sequence is to power up the VDDA (analog) supply first, followed by the VDDC (core) supply, and then the VDDIO (I/O) supply. This ensures proper device operation and prevents latch-up.
To optimize power consumption, use the device's power-saving features such as dynamic voltage and frequency scaling, idle modes, and shutdown modes. Additionally, optimize the system design to minimize power consumption, and use low-power peripherals and interfaces.
The maximum clock frequency for the AM1805AQ is 24 MHz. However, the device can operate at lower frequencies to reduce power consumption and optimize performance.
A reliable reset circuit can be implemented using a voltage supervisor or a reset IC that monitors the power supply voltage and asserts a reset signal to the AM1805AQ when the voltage falls below a certain threshold.
The AM1805AQ has a maximum junction temperature of 125°C. Ensure proper thermal design and heat dissipation to prevent overheating, especially in high-temperature environments or high-power applications.
