Symbol names ending with underscore N (for example, NAME_N) represent active LOW signals.
All outputs and I/O pins can source 4 mA, unless otherwise specified.
Add a decoupling capacitor (0.1 μF) to all the supply pins. For better EMI results, add a 0.01 μF capacitor in
parallel to the 0.1 μF.

Description
bit 13 of bidirectional data bus
bidirectional pad; 4 ns slew-rate control; TTL; 5 V tolerant
bit 14 of bidirectional data bus
bidirectional pad; 4 ns slew-rate control; TTL; 5 V tolerant
bit 15 of bidirectional data bus
bidirectional pad; 4 ns slew-rate control; TTL; 5 V tolerant
supply voltage; used to supply voltage to the I/O pads; see
Section 7.15
USB bus power sensing input — Used to detect whether the
host is connected or not; connect a 1 μF electrolytic or tantalum
capacitor, and a 1 MΩ pull-down resistor to ground; see
Section 7.13
V
electrolytic or tantalum capacitor, and a 1 MΩ pull-down resistor
to ground; see
5 V tolerant
voltage regulator output (1.8 V ± 0.15 V); tapped out voltage
from the internal regulator; this regulated voltage cannot drive
external devices; decouple this pin using 4.7 μF and 0.1 μF
capacitors; see
crystal oscillator output (12 MHz); connect a fundamental
parallel-resonant crystal; leave this pin open when using an
external clock source on pin XTAL1; see
crystal oscillator input (12 MHz); connect a fundamental
parallel-resonant crystal or an external clock source (leaving
pin XTAL2 unconnected); see
supply voltage (3.3 V ± 0.3 V); this pin supplies the internal
voltage regulator and the analog circuit; see
supply voltage (3.3 V ± 0.3 V); this pin supplies the internal
voltage regulator and the analog circuit; see
wake-up input; when this pin is at the HIGH level, the chip is
prevented from getting into the suspend state and wake-up the
chip when already in suspend mode; when not in use, connect
this pin to ground through a 10 kΩ resistor
When the RESET_N pin is LOW, ensure that the WAKEUP pin
does not go from LOW to HIGH; otherwise the device will enter
test mode.
input pad; TTL; 5 V tolerant
suspend state indicator output; used as a power switch control
output to power-off or power-on external devices when going
into suspend mode or recovering from suspend mode
CMOS output; 8 mA drive
ground supply; down bonded to the exposed die pad (heat sink);
to be connected to DGND during PCB layout
BUS
pulsing output — In OTG mode; connect a 1 μF
