NRST pin characteristics
The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up
resistor, RPU (see Table 34).
Unless otherwise specified, the parameters given in Table 37 are derived from tests
performed under ambient temperature and VDD supply voltage conditions summarized in
Figure 22.
Recommended NRST pin
protection
1.
The reset network protects the device against parasitic resets.
2.
The user must ensure that the level on the NRST pin can go below the VIL(NRST) max level specified in
Table 37. Otherwise the reset will not be taken into account by the device.

Weak pull-up equivalent resistor(1)
1.
The pull-up is designed with a true resistance in series with a switchable PMOS. This PMOS contribution to
the series resistance must be minimum
