Battery Draw Down; Electrical And Timing Characteristics - Multitech MultiConnect xDot Developer's Manual

Battery Draw Down

xDot battery life depends on many variables, including transmit power, data rate, sleep usage, and duty cycle. The
following figure represents the current consumption in one possible application.
Use the current consumption values from the following Electrical Characteristics table when calculating average
power consumption.

Electrical and Timing Characteristics

Note:
All measurements taken at VDD = 3.3 V and 25 degrees Celsius ambient temperature unless
otherwise specified.
Refer to the ST Micro STM32L151CC datasheet for more detailed processor IO characteristics.
For Sleep Mode, the value in ( ) is the typical reading when using firmware versions below 4.0.x.
