Valid for ambient operating temperature: TA = –40 to 85 °C; VCC = VRST (max) to 5.5 V; and VBAT = 2.8 V (except where

noted).

VCC supply current, logic input leakage, watchdog functionality, push-button reset functionality, PFI functionality,

state of RST and RST tested at VBAT = 3.6 V, and VCC = 5.5 V. The state of RST or RST and PFO is tested at VCC = VCC

(min). Either VCC or VBAT can go to 0 V if the other is greater than 2.0 V.

VCC (min) = 1.0 V for TA = 0 °C to +85 °C.

Tested at VBAT = 3.6 V, VCC = 3.5 V and 0 V.

Guaranteed by design.

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).

Not valid for STM795/804/805 (open drain).

When VBAT > VCC > VSW, VOUT remains connected to VCC until VCC drops below VSW.

When VSW > VCC > VBAT, VOUT remains connected to VCC until VCC drops below the battery voltage (VBAT) - 75 mV.

10. The reset threshold tolerance is wider for VCC rising than for VCC falling due to the 10 mV (typ) hysteresis, which prevents

internal oscillation.
