Symbol names with an overscore (e.g. NAME) indicate active LOW signals.

Down bonded to the exposed diepad.
VCC(I/O)
7
-
Supply voltage for digital I/O pins (1.65 to 3.6 V). When
VCC(I/O) is not connected, the pins (D+, D) are in three-state.
This supply pin is totally independent of VCC(5.0) and Vreg(3.3)
and must never exceed the Vreg(3.3) voltage.
VBUSDET
8
O
VBUS indicator output (CMOS level with respect to VCC(I/O)).
When VBUS is above 4.0 V, then the output is HIGH and when
VBUS is below 3.6 V, then the output is LOW.
D
9
AI/O
negative USB data bus connection (analog, differential)
D
+
10
AI/O
positive USB data bus connection (analog, differential);
connect a 1.5 k
resistor to pin Vpu(3.3)
VPO/VO
11
I
driver data input (CMOS level with respect to VCC(I/O), Schmitt
VMO/FSE0
12
I
driver data input (CMOS level with respect to VCC(I/O), Schmitt
Vreg(3.3)
13
-
regulated supply voltage output (3.0 to 3.6 V); a decoupling
capacitor of at least 0.1
F is required
VCC(5.0)
14
-
supply voltage input (4.0 to 5.5 V); can be connected directly
to the USB supply line VBUS
Vpu(3.3)
15
-
pull-up supply voltage (3.3 V
± 10%); connect an external
1.5 k
resistor on D+ (full-speed); pin function is controlled by
input SOFTCON:
SOFTCON = LOW — Vpu(3.3) oating (high impedance);
ensures zero pull-up current
SOFTCON = HIGH — Vpu(3.3) = 3.3 V; internally connected to
Vreg(3.3)
SOFTCON
16
I
software controlled USB connection input; a HIGH level
applies 3.3 V to pin Vpu(3.3), which is connected to an external
1.5 k
pull-up resistor; this allows USB connect or disconnect
signalling to be controlled by software
