NAME
DESCRIPTION/TYPE
31
GPIO16
GPIO
32
GND
33
DOUT3V0
3V (Doubler) Output. While DHAN-T is hibernating,
this pin is either in tristate (default SW
configuration) or pulled to GND. Can be used in
conjunction with GPIO7&8 above to drive an LED
or button during non-hibernation modes
34
DOUBCAP2P
Pull down with 1M resistor
35
LEDSINK2/DCIN1
ULE I/O. If not used, can be left NC
36
GND
GND
37
LEDSINK1/PWM
38
DCIN3
ADC input used to monitor power supply input
39
AMP2_OUT
ULE I/O. Typically used (as input) to wake up the
DHAN-T from hibernation
40
AMP1_OUT
ULE I/O. Typically used (as output) to indicate
DHAN-T is active (logic high)
41
ANA2_IN
ULE I/O. During hibernate, Logic High should not
be applied to this pin (it can result in leakage
current). If not used, can be left NC
42
MPWR
Microphone Power
43
MIN
If not used, can be left as NC
44
MIP
If not used, can be left as NC
45
ANA_IN1
ULE I/O. If not used, can be left NC
46
SPOUTP
Speaker Output, Positive
47
SPOUTN
Speaker Output, Negative
48
HSSPOTP
Headset Speaker Out, Positive
49
LOUT
Headset Speaker Out, Negative
50
PWM0
Analog Output
51
XIN_32K
Connect to 32.768 XTAL
52
XOUT_32K
Connect to 32.768 XTAL
53
VDD_ULE
1.8V output. Active during hibernate. Can be used to
power VCC_GPIO (Pin16)
54
VDD_APU
1.8V Test Point. Leave NC
55
VBAT
Power Supply Input. Connect to Battery or regulated
3V supply
