NRST pin characteristics

The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up

resistor, RPU (see Table 54).

Unless otherwise specified, the parameters given in Table 57 are derived from tests

performed under the ambient temperature and VDD supply voltage conditions summarized

in Table 14. Refer to Table 54: I/O static characteristics for the values of VIH and VIL for

NRST pin.

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 (~10% order)

2. Guaranteed by design, not tested in production.
