3 Electrical specifications
Warning ：
Stressing t
he device above one or more of the ratings listed in the Absolute
maximum rating section may cause permanent damage. These are stress ratings only.
Operating the module at
these or at any c
onditions other than those specified in the Operating conditions section of this
document should be avoided. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
Notice:
Operating c
ondition ranges define those limits within which the functionality of the
device is guaranteed. Where application information is given, it is advisory only and does not
form part of
the specifi
cation.

Warning ：
The product is not p
rotected against overvoltage or reversed voltages. If necessary,
voltage spikes exceeding the power supply voltage specification, given in table above, must be
limited to values
within the speci
fied boundaries by using appropriate protection devices.
3.2 Operating conditions
Notice:
Unless otherwi
se specified, all operating condition specifications are at an ambient
temperature of 25 °C and a supply voltage of 3.0 V.
Warning ：
Operation beyond th
e specified operating conditions is not recommended and extended
exposure beyond them may affect device reliability.

3.3 General purpose I/O
The general purpose I
/O is organized as one port enabling access and control of the 32 available GPIO
pins via one port, P0. Each GPIO can be accessed with the following user configurable features:
• Input/output dir
ection
• Output drive str
ength
• Internal pull-up and p
ull-down resistors
• Wake-up from high- or low-l
evel triggers on all pins
• Trigger interru
pt on all pins
• All pins can
be used by the PPI task/event system; the maximum number of pins that can be
interfaced through the PPI at the same time is limited by the number of GPIOTE channels
• All pins can be individually configured to carry serial interface or quadrature demodulator signals
