STM690/704/795/802/804/805/806
Note: 1. Valid for Ambient Operating Temperature: TA = –40 to 85°C; VCC = VRST (max) to 5.5V; and VBAT = 2.8V (except where noted).
2. VCC supply current, logic input leakage, Watchdog functionality, Push-button Reset functionality, PFI functionality, state of RST and
RST tested at VBAT = 3.6V, and VCC = 5.5V. The state of RST or RST and PFO is tested at VCC = VCC (min). Either VCC or VBAT
can go to 0V if the other is greater than 2.0V.
3. VCC (min) = 1.0V for TA = 0°C to +85°C.
4. Tested at VBAT = 3.6V, VCC = 3.5V and 0V.
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 VBAT > VCC > VSW, VOUT remains connected to VCC until VCC drops below VSW.
9. When VSW > VCC > VBAT, VOUT remains connected to VCC until VCC drops below the battery voltage (VBAT) – 75mV.
10. The reset threshold tolerance is wider for VCC rising than for VCC falling due to the 10mV (typ) hysteresis, which prevents internal
oscillation.
