5 Application Information
5.1
Supply Voltage Decoupling
For better stability we recommend to add a 100nF capacitor to each power supply pin and an additional
47F tantalum capacitor to the VIN voltage rail next to the module.
5.2
Reset circuit
The integrated Reset circuit monitors the 3.3V power rail. If this voltage drops below 2.93V, the
RESET signal
will be asserted. If the 3.3V voltage domain rises above this threshold,
RESET will be kept low for 140 to
280ms and will be released afterwards.
The
RESET signal is an open collector output with an internal pull-up resistor of 470. This signal can be used
as external manual reset by connecting an external push-button that ties the signal to ground.
