PSoC™ 6 MCU (P6.VDD) and AIROC™ CYW43012 Wi-Fi & Bluetooth® combo chip (VBAT) after board
initialization and association with the AP. The yellow pulse represents the AIROC™ CYW43012 Wi-Fi &
Bluetooth® combo chip current and the green pulse represents the PSoC™ 6 MCU current. The AP is
configured for a beacon interval of 100 ms and DTIM = 1 and an interval of 100 ms and DTIM = 2.
Note that the average power consumption will vary between DTIM intervals. This is because of other
activities in the Wi-Fi spectrum (2.4 GHz or 5 GHz) such as other Wi-Fi networks, Bluetooth® (2.4 GHz) or
Long-Term Evolution (LTE in 2.4 GHz) interference that increase the duration for which AIROC™ CYW43012
Wi-Fi & Bluetooth® combo chip listens for DTIM packet from the AP. This type of activity will increase the
average power consumption. To obtain the datasheet numbers, measure power in a shielded environment
to avoid any interference.
