Recommended
operating
conditions
Recommended operating conditions specify voltage and temperature ranges over
which a circuit’s correct logic function is guaranteed. The specified DC electrical
characteristics (see "DC electrical characteristics," beginning on page 79) are
satisfied over these ranges.
For operating temperatures, see “Environmental information” on page 65.

Power dissipation
The typical power dissipation for the ConnectCore 9C module is 1.6W.
..................................................................................
The typical power dissipation for the ConnectCore Wi-9C module at 3.3V, is 2.75W.
The maximum power dissipation is 3.25W at 3.46V, when the radio is continuously
transmitting. Note that these values do not include USB power.
DC electrical characteristics
DC characteristics specify the worst-case DC electrical performance of the I/O
buffers that are guaranteed over the specified temperature range.
