4 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.

⚠ NINA-B40 series modules are Electrostatic Sensitive Devices and require special precautions while
handling. See section 8.4 for ESD handling instructions.
4.2 Operating conditions
☞ Unless otherwise specified, all given operating condition specifications are taken for an ambient
temperature of 25 °C with a supply voltage of 3.3 V.
⚠ Operation beyond the specified operating conditions is not recommended. Any extended exposure
outside of these specific limits can affect the device reliability.
⚠ The RAM Data retention endurance is 10,000 write/erase cycles (10 years) throughout the
temperature range up to 85 °C. RAM Data retention is limited to 1000 write/erase cycles (3 years)
at extended temperature range of 105 °C.
