1. Includes the ADC conversion of the analog Temperature Sense voltage.
2. The ADC is not calibrated for the conversion of the Temperature Sensor trim value stored in the Flash Memory at
FMOPT0 and FMOPT1.
3. See Application Note, AN1980, for methods to increase accuracy.
4. Assuming a 12-bit range from 0V to 3.3V.

10.3 AC Electrical Characteristics
Tests are conducted using the input levels specified in Table 10-5. Unless otherwise specified,
propagation delays are measured from the 50% to the 50% point, and rise and fall times are measured
between the 10% and 90% points, as shown in Figure 10-2.

Figure 10-2 Input Signal Measurement References
Figure 10-3 shows the definitions of the following signal states:
•
•
•
Active state, when a bus or signal is driven, and enters a low impedance state
Tri-stated, when a bus or signal is placed in a high impedance state
Data Valid state, when a signal level has reached VOL or VOH
•
Data Invalid state, when a signal level is in transition between VOL and VOH
