Customer wants to confirm below information:
When dropping the power supply (VDDIN) voltage of the BT module,
is it OK to drop the VDDIN power supply immediately without setting a reset?
(* At power-on, after VDDIN stabilizes, wait for + 50ms to release reset.)
Hi YoJa_3107936 ,
It is OK only if VDDIN is driven to real low. If VDDIN isn’t driven to real low and then driven to high, the chip is possible in uncertain status (“At power-on, after VDDIN stabilizes, wait for + 50ms to release reset” won’t be met with).
