Low-voltage inhibit, trip falling voltage
Low-voltage inhibit, trip rising voltage
Low-voltage inhibit reset/recovery hysteresis
Internal operating frequency
RST input pulse width low
TIM2 external clock input
IRQ interrupt pulse width low (edge-triggered)
IRQ interrupt pulse period
1. V
2. Typical values reflect average measurements at midpoint of voltage range, 25 °C only.
3. Run (operating) I
4. Wait I
5. Stop I
6. Maximum is highest voltage that POR is guaranteed.
7. If minimum V
8. R
1. V
2. Minimum pulse width reset is guaranteed to be recognized. It is possible for a smaller pulse width to cause a reset.
3. Values are based on characterization results, not tested in production.
4. The minimum period is the number of cycles it takes to execute the interrupt service routine plus 1 t
