Electrical characteristics

Figure 21. Recommended NRST pin protection

1. The reset network protects the device against parasitic resets.

2. The external capacitor must be placed as close as possible to the device.

3. The user must ensure that the level on the NRST pin can go below the VIL(NRST) max level specified in

Table 51. Otherwise the reset will not be taken into account by the device.

12-bit ADC characteristics

Unless otherwise specified, the parameters given in Table 52 are values derived from tests

performed under ambient temperature, fPCLK frequency and VDDA supply voltage conditions

summarized in Table 15: General operating conditions.

Note:

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