Reset pin Status

bsuthar · ‎2025-08-02

Hello team,

Generally , Reset pin by default status is Logic High.

But in AN4206 ( Page 31) , NRST pin is not Connected to 3.3V , it is left Floating with Capacitor.

Is that Okay ?

My device is STM32F303.

Yes, the typical connection is floating with 0.1 uF cap. It is internally pulled up.
