9. Power Supply
These devices incorporate an on-chip voltage regulator to power the device from supply voltages of 1.8, 2.5, or
3.3 V. Internal core circuitry is driven from the output of this regulator while I/O circuitry uses the external supply
voltage directly.
Figure 57 shows a typical power supply bypass network for the TQFP packages. Figure 58 shows a typical power
supply bypass network for QFN.
In both cases, the center ground pad under the device must be electrically and thermally connected to the ground
plane.
