Recommendations
Decoupling Capacitor:
A decoupling capacitor of 0.1μF must be used between VDD and VSS pins. Place the
capacitor on the component side of the PCB as close to the VDD pin as possible. The PCB trace to the VDD pin and
to the GND via should be kept as short as possible. Do not use vias between the decoupling capacitor and the VDD
pin.
