Product Information Data Sheet
The WiFi firmware does not incorporate any support for writing to the EEPROM during normal operation. This
significantly reduces the risk of spurious writes corrupting the contents of the EEPROM, and means it is not possible
to repair any damage that may occur. Hence, it is suggested that keep the pin, WL_WP, permanently pulled high to
tia
minimize the risk of data corruption.

1-6-1 WiFi Reset
WL_RESETn is an active low reset input that is internally filtered using the internal low frequency clock oscillator
to avoid spurious resets. A reset occurs after the signal has been asserted for between 250 and 375us. This pin may be
tied to WL_VDD_PADS_0_7 if unused; otherwise it should be asserted for at least 1ms to force a reset.
The power supply supervisor monitors WL_VDD_CORE (internal module voltage) to trigger a power-on-reset.
This occurs when the supply falls below 1.05V (typical) in normal operation or 0.825V (typical) in deep sleep, and ends
when the supply exceeds 1.10V (typical). Glitches of up to 30mV and 2.5us duration, which could be caused by large
co
load steps, will not trigger a reset.
Each of the internal processors has its own independent watchdog timer to detect and recover from erroneous
software operation. These are typically configured with a timeout of 1.5s, but this may be increased up to a maximum of
64s for reduced power consumption. The watchdogs are enabled at power-on and continue operating while WiFi is in
deep sleep.
ap
During all forms of reset most digital I/O pins (including both bidirectional pins and dedicated inputs or outputs)
default to high impedance with weak internal pull-downs. The only exceptions are WL_RESETn and WL_SPI_CS
which both have pull-ups, and the SDIO/CSPI bus which is on an independent reset domain. The SDIO/CSPI host
interface is only fully reset by the WL_RESETn pin or the power supply supervisor; other forms of reset leave the host
interface initialized but simply clear the I/O Enable bit for function 1.
Following a reset, WiFi automatically generates safe clocks for internal use. If an external reference clock is
connected to WL_CLK then this is assumed to be at the maximum supported frequency, otherwise the PLL free runs at

The BT_RESETB pin is an active low reset and is internally filtered using the internal low frequency clock
oscillator. A reset is performed between 1.5 and 4.0ms following BT_RESETB being active. It is recommended that
BT_RESET be applied for a period greater than 5ms.
The power on reset occurs when the BT_VDD_CORE supply falls below 1.24V and is released when
BT_VDD_CORE rises above typically 1.31V. At reset the digital I/O pins are set to input for bi-directional pins and
outputs are tri-state. Following a reset, BT assumes the maximum BT_CLK frequency, which ensures that the internal
clocks run at a safe (low) frequency until BT is configured for the actual BT_CLK frequency. If no clock is present at
BT_CLK, the oscillator in BT free runs, again at a safe frequency.
