NRST and NRST_CORE pin characteristics

The NRST and NRST_CORE pins input driver uses CMOS technology. It is connected to a

permanent pull-up resistor, RPU (see Table 50: I/O static characteristics).

Unless otherwise specified, the parameters given in Table 56 are derived from tests

performed under the ambient temperature and VDD supply voltage conditions summarized

in Table 13: General operating conditions.

1. Guaranteed by design.

2. The maximum frequency is defined with the following conditions: (tr+tf) ≤ 2/3, skew ≤ 1/20 T and 45% < Duty cycle < 55%.

3. The fall and rise times are defined between 90% and 10% and between 10% and 90% of the output waveform,

respectively.

4. Compensation system enabled.
