Low-power system design with AIROC™ Wi-Fi & Bluetooth® combo
chip and PSoC™ 6 MCU
Power measurement using CY8CKIT-062S2-43012
Figure 30 Test network setup
4. To realize the capability of WLAN offloads and their impact on the host MCU in terms of power savings, the
current measurement has been done by considering the following cases.
5. To simulate a congested network environment, another Wi-Fi client device has associated to the same
network to which the target kit has associated. In all these current measurement cases, the role of the client
device is to send ping and ARP request packets periodically in its configured interval to the IP address of the
target kit. Based on whether the LPA offloads are enabled, the host MCU will stay in Deep Sleep power mode
or wake up due to the ping and arp-ping requests from the client device.
6. WLAN offloads can be enabled or disabled in the Wi-Fi parameters using the Device Configurator.
Note: PSoC™ 6 MCU and Wi-Fi device current numbers were measured and averaged over 20 seconds in
all the following cases. Current measurements are taken when the associated Wi-Fi client sends a
ping request every 5 seconds and an arp-ping request every 10 seconds to the IP address of the
target kit.
