1. Valid for ambient operating temperature: T

= 3.6 V, V
CC
= 3.5 V and 0 V.
5. Guaranteed by design.
6. The leakage current measured on the RST pin (STM804/805) or RST
pin (STM795) is tested with the reset output not
asserted (output high impedance).
7. Not valid for STM795/804/805 (open drain).
8. When V

remains connected to V
CC
until V

.
9. When V

> V
CC
> V
BAT
, V
OUT
remains connected to V
CC
until V
CC
drops below the battery voltage (V
BAT
) - 75 mV.
10. The reset threshold tolerance is wider for V
CC
rising than for V
CC
falling due to the 10 mV (typ) hysteresis, which prevents
internal oscillation.
