DYNAMIC ELECTRICAL CHARACTERISTICS
Table 4. Dynamic Electrical Characteristics
Characteristics noted under conditions VDD = 3.6 V, VBUS = 5.0 V, VDDIO = 3.0 V, -40°C ≤ TA ≤ 85°C (see Figure 1), unless
otherwise noted. Typical values noted reflect the approximate parameter means at VDD = 3.6 V and TA = 25°C under nominal
conditions, unless otherwise noted.
