BCM43455 Datasheet, PDF (139/159 Pages) Cypress Semiconductor – Single-Chip 5G WiFi IEEE 802.11ac MAC/Baseband/ Radio with Integrated Bluetooth 4.1 and FM Receiver

BCM43455 Preliminary Data Sheet
Bluetooth Current Consumption
a. V_IO is specified with all pins idle (not switching) and not driving any loads.
b. WL_REG_ON and BT_REG_ON are both low. All supplies present.
c. Idle, not associated, or inter-beacon.
d. Beacon Interval = 102.4 ms. Beacon duration = 1ms @ 1Mbps. Average current over 3x DTIM intervals.
e. Duty cycle is 100%. Carrier sense (CS) detect/packet receive.
f. Measured using packet engine test mode.
g. Carrier sense (CCA) when no carrier present.
h. Duty cycle is 100%.
Bluetooth Current Consumption
The Bluetooth and BLE current consumption measurements are shown in Table 52.
Note: The WLAN core is in reset (WLAN_REG_ON = low) for all measurements provided in Table 52.
Note: The BT current consumption numbers are measured based on GFSK TX output power =
10 dBm.
