5.5.2 Power Consumption
The power consumptions of MC509 in different scenarios are respectively listed in
Table 5-6 .
The power consumption listed in this section is tested when the power supply of
MC509 module is 3.8V. Typical values are measured at room temperature, and
minimum and maximum values are measured over the entire operating temperature
range.
