12 ELECTRICAL CHARACTERISTICS

12.1 PARAMETER CONDITIONS

Unless otherwise specified, all voltages are re-

ferred to VSS.

12.1.1 Minimum and Maximum values

Unless otherwise specified the minimum and max-

imum values are guaranteed in the worst condi-

tions of ambient temperature, supply voltage and

frequencies by tests in production on 100% of the

devices with an ambient temperature at TA=25°C

and TA=TAmax (given by the selected temperature

range).

Data based on characterization results, design

simulation and/or technology characteristics are

indicated in the table footnotes and are not tested

in production. Based on characterization, the min-

imum and maximum values refer to sample tests

and represent the mean value plus or minus three

times the standard deviation (mean±3

Σ).

12.1.2 Typical values

Unless otherwise specified, typical data are based

on TA=25°C, VDD=5V.They are given only as de-

sign guidelines and are not tested.

12.1.3 Typical curves

Unless otherwise specified, all typical curves are

given only as design guidelines and are not tested.

12.1.4 Loading capacitor

The loading conditions used for pin parameter

measurement are shown in Figure 84.

12.1.5 Pin input voltage

The input voltage measurement on a pin of the de-

vice is described in Figure 85.
