Hi all,

Why PORST voltage level after PORST release is a bit lower than VEXT(e.g. 5V)?

Best regards,
Lina.

Hi Lina,

There is a weak pull-down internally in the PORST pad. It is for keeping PORST weakly pulled low in case of bond wire breakage. The pull down is inactive to avoid additional current during STANDBY mode.

Best regards,
Mr. AURIX™
