I-R
USB Transceiver Bias
A 12.0 k
Ω, ±1.0% resistor is attached from VSS to this
pin in order to set the transceiver's internal bias
currents.
XTAL1 (CLKIN)
33
ICLKx
24 MHz Crystal (External clock input)
This pin can be connected to one terminal of the
crystal or can be connected to an external 24 MHz
clock when a crystal is not used.
XTAL2
32
OCLKx
24 MHz Crystal
This is the other terminal of the crystal, or it is left open
when an external clock source is used to drive
XTAL1(CLKIN). It may not be used to drive any
external circuitry other than the crystal circuit.
VDDA33

3.3 V Analog Power
VDD18PLL
34
1.8 V PLL Power
+1.8 V Filtered analog power for internal PLL. This pin
must have a 1.0
μF(or greater) ±20% (ESR <0.1 Ω)
capacitor to VSS.
MISC
GPIO1 (LED)
1
I/O12
General Purpose I/O (GPIO): This pin may be used
either as input, edge sensitive interrupt input, or
output. Custom firmware is required to activate this
function.
LED: GPIO1 can be used as an LED output.
