BCM4356 Advance Data Sheet
Sequencing of Reset and Regulator Control Signals
Figure 49: WLAN = ON, Bluetooth = OFF
32.678 kHz
Sleep Clock
VBAT*
90% of VH
VDDIO
~ 2 Sleep cycles
WL_REG_ON
BT_REG_ON
*Notes:
1. VBAT should not rise 10%â90% faster than 40 microseconds.
2. VBAT should be up before or at the same time as VDDIO . VDDIO should NOT be present first or be held high before VBAT is high .
