ELECTRICAL CHARACTERISTICS

STATIC ELECTRICAL CHARACTERISTICS

Table 3. Static Electrical Characteristics (continued)

Characteristics noted under conditions V_DD= 3.6 V, V_BUS= 5.0 V, V_DDIO= 3.0 V, -40°C ≤ T_A≤ 85°C (see Figure 1), unless

otherwise noted. Typical values noted reflect the approximate parameter means at V_DD= 3.6 V and T_A= 25°C under nominal

conditions, unless otherwise noted.
