5. Characteristics and Specifications

Note:

All data sheet minimum and maximum timing parameters are guaranteed over the rated voltage and

temperature. All data sheet typical parameters are measured under the following conditions: T = 25 °C,

VDD = 1.8 V, VDDIO = VDDA =3.3 V, GND = GNDIO = GNDA = 0 V.

5.1 Absolute Maximum Ratings

(GND = GNDIO = GNDA = 0 V; all voltages with respect to 0 V)

not guaranteed at these extremes.

5.2 Recommended Operating Conditions

(GND = GNDIO = GNDA = 0 V; all voltages with respect to 0 V)

5.3 Digital DC Characteristics

(Measurements performed under static conditions.)
