USB power supply, output by the on-chip USB
3.3V linear regulator.
Note: An external decoupling capacitor (typ.
100nF, min 47nF) must be connected between
this pin and USBV
USB Power supply voltage (4V - 5.5V) also
used by the regulator and PLL
Note: External decoupling capacitors (typ.
4.7µF+100nF, min 2.2µF+100nFmust be con-
nected between this pin and USBV
Power Line for alternate supply rail. Can be
used as input (with external supply) or output
(when using the on-chip voltage regulator).
Note: An external decoupling capacitor (min.
20nF) must be connected to this pin to stabilize
the regulator.
Ground Line for alternate supply rail. Can be
used as input (with external supply) or output
(when using the on-chip voltage regulator)
