1 Typical values are based on characterization data at V
DD = 5.0 V, 25 C unless otherwise stated.
2 This is the shortest pulse that is guaranteed to be recognized as a reset pin request. Shorter pulses are not guaranteed
to override reset requests from internal sources.
3 This is the minimum pulse width that is guaranteed to pass through the pin synchronization circuitry. Shorter pulses may
or may not be recognized. In stop mode, the synchronizer is bypassed so shorter pulses can be recognized in that case.
4 Timing is shown with respect to 20% V
DD and 80% VDD levels. Temperature range –40 C to 105 C.
