Note: VDDIO must be greater or equal to VBATT. CYW20819 uses an on-chip low-voltage detector to shut
down the chip when supply voltage (VBATT) drops below the operating range. The shutdown
voltage (V
SHUT
) lies between a minimum of 1.5 V and a maximum of 1.7 V. See the datasheet for
more details.

Description
SW1 GND RECOVER Recovery button* (Red)
SW2 GND RST_N Active LOW Reset button (Blue)
SW3 GND P0 User application button (Black)
Note: *See the Recovery button (SW1): under Theory of operation .
The switch SW4 enables or disables the two onboard user LEDs. By default, both LED1 and LED2 are enabled.

POS 2 OFF NC Enables DMIC_CLK
OFF NC Enables DMIC_DATA
SW8 is a slide switch. Pos 1 allows RSVD_4 and RSVD_5 to be used for SWD functionality for the debugger
interface. Pos 2 allows P2 and P3 to be used for SWD functionality for the debugger interface and when using P2
and P3 as GPIOs, keep SW8 in the Pos2 position.
