Electrical characteristics

Figure 19. 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 52: NRST pin characteristics. Otherwise the reset will not be taken into account by the device.

3. The external capacitor on NRST must be placed as close as possible to the device.

Analog-to-digital converter characteristics

Unless otherwise specified, the parameters given in Table 53 are preliminary values derived

from tests performed under ambient temperature, fPCLK frequency and VDDA supply voltage

conditions summarized in Table 23: General operating conditions.

Note:

It is recommended to perform a calibration after each power-up.
