3 Electrical specifications
⚠ Stressing the 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 conditions 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.
☞ Operating condition 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 specification.

⚠ The product is not protected 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 specified boundaries by using appropriate protection devices.
3.2 Operating conditions
☞ Unless otherwise specified, all operating condition specifications are at an ambient temperature
of 25 °C and a supply voltage of 3.3 V.
⚠ Operation beyond the specified operating conditions is not recommended and extended exposure
beyond them may affect device reliability.
