CYBT-343052-02
External Reset (XRES)
The CYBT-343052-02 has an integrated power-on reset circuit that completely resets all circuits to a known power-on state. An
external active low reset signal, XRES, can be used to put the CYBT-343052-02 in the reset state. The XRES pin has an internal
pull-up resistor and, in most applications, it does not require anything to be connected to it.

Brownout Detection
An external voltage detector reset IC may be used if brownout detection is required. The reset IC should release RESET_N only after
the VDDO supply voltage level has been at or above a minimum operating voltage for 50 ms or longer.
