5 Characteristics and Specifications
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 = 0V; all voltages with respect to 0V)
WARNING: Operation at or beyond these limits can result in permanent damage to the device. Normal operation is not
guaranteed at these extremes.
5.2 Recommended Operating Conditions
(GND = GNDIO = GNDA = 0V; all voltages with respect to 0V)
Note: It is recommended that the 3.3 V IO supply come up ahead of or simultaneously with the 1.8 V core supply.
