6.1.7 Current consumption measurement
Figure 23. Current consumption measurement scheme
6.2 Absolute maximum ratings
Stresses above the absolute maximum ratings listed in Table 14: Voltage characteristics,
Table 15: Current characteristics, and Table 16: Thermal characteristics may cause
permanent damage to the device. These are stress ratings only and functional operation of
the device at these conditions is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
Device mission profile (application conditions) is compliant with JEDEC JESD47
Qualification Standard, extended mission profiles are available on demand.
