The recommended operating voltage range for the 6A20 is 1.71V to 3.6V, with a typical voltage of 2.5V.
The POR circuitry in the 6A20 is designed to reset the device during power-up. To handle POR, ensure that the power supply voltage rises monotonically and reaches the minimum operating voltage (1.71V) within 10ms. This ensures a clean reset and prevents unwanted resets during power-up.
The 6A20 supports a maximum clock frequency of 20MHz, but this can be adjusted based on the specific application and power consumption requirements.
To optimize power consumption in the 6A20, use the power-down mode, reduce the clock frequency, and minimize the use of peripherals when not needed. Additionally, consider using the device's built-in power-saving features, such as the idle mode and sleep mode.
The maximum current rating for the I/O pins in the 6A20 is 4mA per pin, with a total current limit of 100mA for all I/O pins combined.
