PIN DESCRIPTION (Cont’d)
Legend / Abbreviations:
Type: I = input, O = output, S = supply
VDDF powered: I/O powered by the alternate sup-
ply rail, supplied by VDDF and VSSF.
In/Output level: CT = CMOS 0.3VDD/0.7VDD with
input trigger
Output level: HS = High Sink (on N-buffer only)
Port and control configuration:
– Input:float = floating, wpu = weak pull-up, int = in-
terrupt
– Output: OD = open drain, T = true open drain, PP
= push-pull, OP = pull-up enabled by option byte.
Refer to “I/O PORTS” on page 45 for more details
on the software configuration of the I/O ports.
The RESET configuration of each pin is shown in
bold.

USBVCC
O
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
USBVSS.
5USBVDD
S
USB Power supply voltage (4V - 5.5V) also used by
the regulator and PLL
Note: External decoupling capacitors (typ.
4.7F+100nF, min 2.2F+100nFmust be connected
between this pin and USBVSS.
6VDDF
SX
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 decou-
pling capacitor (min. 20nF) must be connected to this
pin to stabilize the regulator.
7VSSF
SX
Ground Line for alternate supply rail. Can be used as
input (with external supply) or output (when using the
on-chip voltage regulator)
