WLAN POWER-UP SEQUENCE
The information in this document is subject to change without notice.
330-0045-R4.0
The following sequence describes device power-up from shutdown. Only the WLAN Core is enabled; the
Bluetooth and FM cores are disabled.
1. No signals are allowed on the IO pins if no IO power is supplied, because the IOs are not 'fail safe’.
2. VBAT, VIO, and SLOWCLK must be available before WL_EN.
3. T
The duration of T1 is defined as the time from WL_EN=high until F
The duration of T2 depends on:
– Operating system
– Host enumeration for the SDIO/WSPI
– PLL configuration
– Firmware download
– Releasing the core from reset
– Firmware initialization
Exceptions are CLK_REQ_OUT, SLOWCLK, XTALP, and AUD_xxx, which are failsafe and can
tolerate external voltages with no VDDS and DC2DC".
