3.1 Test Conditions

Unless otherwise specified and noted, all voltages are referenced to VSS.

All minimum and maximum values are guaranteed under the worst environmental temperature, supply voltage, and clock frequency conditions. Typical values are based on normal temperature 25°C and VDD = 3.3V or 5V environment for design guidance.

Data obtained through comprehensive evaluation, design simulation, or process characterization will not be tested on the production line. Based on comprehensive evaluation, minimum and maximum values are statistically obtained after sample testing. Unless specifically stated as measured values, characteristic parameters are guaranteed by comprehensive evaluation or design.
