CYW4343X
20. System Power Consumption
Note: The values in this data sheet are design goals and are subject to change based on device characterization.Unless otherwise
stated, these values apply for the conditions specified in Table 30, “Recommended Operating Conditions and DC Characteristics,” on
page 91.
20.1 WLAN Current Consumption
Table 46 shows typical currents consumed by the CYW4343X’s WLAN section. All values shown are with the Bluetooth core in Reset
mode with Bluetooth and FM off.

a. Device is initialized in Sleep mode, but not associated.
b. Device is associated, and then enters Power Save mode (idle between beacons).
c. Beacon interval = 100 ms; beacon duration = 1 ms @ 1 Mbps (Integrated Sleep + wakeup + beacon).
d. Beacon interval = 300 ms; beacon duration = 1 ms @ 1 Mbps (Integrated Sleep + wakeup + beacon).
e. Carrier sense (CCA) when no carrier present.
f.
Tx output power is measured on the chip-out side; duty cycle =100%. Tx Active mode is measured in Packet Engine mode (pseudo-random data)
