POWER SUPPLY
GND Center Pad Ground The ground center pad is the metal contact at the bottom of the package. This pad must be connected to the GND plane. At least 15 PCB vias are recommended to minimize inductance and provide a solid ground. Refer to the package drawing (RLJ-package) for the via placement.
VCC 3, 6, 7, 10, 13, 19, 22, 25, 26, 29, 32, 38 Power Power supply 2.5 V ±5%, 3.3 V ±5%
