NRST pin characteristics

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

resistor, RPU (see Table 53).

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

performed under ambient temperature and VDD supply voltage conditions summarized in

Table 23.

1. Guaranteed by design, not tested in production.

2. 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).
