Basic Connection Requirements
The device requires a nominal 3.3V supply voltage. The following pins need to be connected:
•
All VDD and VSS pins need connection to the supply voltage and decoupling capacitors
•
VCORECAP: The devices’ core and digital logic is designed to operate at a nominal 1.8V, which is
provided by an on-chip regulator. The required core logic voltage is derived from VDD and is
outputted on the VCORECAP pin. A low-ESR capacitor (such as tantalum) must be connected to the
VCORECAP pin. This helps to maintain the stability of the regulator.
•
AVDD: Analog voltage references for the ADC needs to be connected to the supply voltage and a
decoupling capacitor
•
VANA: Analog supply for GestIC analog front end must be connected to the supply voltage
