3 Electrical Characteristics
3.1 Test Conditions
3.1.1 Typical Values
The typical data are based on TAMB=25°C and VDD=3.0 V, as defined in Table 3.2 (p. 10) , by simu-
lation and/or technology characterisation unless otherwise specified.
3.1.2 Minimum and Maximum Values
The minimum and maximum values represent the worst conditions of ambient temperature, supply volt-
age and frequencies, as defined in Table 3.2 (p. 10) , by simulation and/or technology characterisa-
tion unless otherwise specified.
3.2 Absolute Maximum Ratings
The absolute maximum ratings are stress ratings, and functional operation under such conditions are
not guaranteed. Stress beyond the limits specified in Table 3.1 (p. 10) may affect the device reliability
or cause permanent damage to the device. Functional operating conditions are given in Table 3.2 (p.
