Temperature and VDD thresholds monitoring
Temperature and upper VDD voltage monitoring characteristics for tamper detection are
detailed in the table below:
5.3.27
DFSDM characteristics
Unless otherwise specified, the parameters given in Table 124 for DFSDM are derived from
tests performed under the ambient temperature, fAPB2 frequency and VDD supply voltage
conditions summarized in Table 27: General operating conditions.
•
Output speed is set to OSPEEDRy[1:0] = 10
•
Capacitive load C = 30 pF
•
Measurement points are done at CMOS levels: 0.5 x VDD
Refer to Section 5.3.15: I/O port characteristics for more details on the input/output alternate
function characteristics (DFSDM1_CKINy, DFSDM1_DATINy, DFSDM1_CKOUT for
DFSDM).
