BCM4339 Preliminary Data Sheet
Bluetooth and FM Current Consumption
Bluetooth and FM Current Consumption
The Bluetooth, BLE, and FM Bluetooth BLE current consumption measurements are shown in Table 51.
Note:
•
•
•
The WLAN core is in reset (WLAN_REG_ON = low) for all measurements provided in Table 51.
For FM measurements, the Bluetooth core is in Sleep mode.
The BT current consumption numbers are measured based on GFSK TX output power = 10 dBm.
