NRST pin characteristics

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

up resistor, RPU.

Unless otherwise specified, the parameters given in the table below are derived from tests

performed under the ambient temperature and supply voltage conditions summarized in

Table 21: General operating conditions.

1. Data based on design simulation only. 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 is minimal (~10% order).

3. Data based on design simulation only. Not tested in production.
