BCM43903 Preliminary Data Sheet
System Power Consumption
Section 16: System Power Consumption
Note: Values in this data sheet are design goals and are subject to change based on the results of
device characterization.
Note: Unless otherwise stated, these values apply for the conditions specified in
Table 15: “Recommended Operating Conditions and DC Characteristics,” on page 59.
WLAN Current Consumption
The tables in this subsection show the typical, total current used by the BCM43903. Current values may be
measured with the APPS core powered off. The first column of the table, the mode description, will state the
power condition of the APPS core.
