Chapter 4 Electrical Characteristics
The following conditions are assumed unless otherwise specified:
V
VBAT
= 3.1 to 5.5V; V
DD18
= 1.6 to 2.0V; V
DDIO
= 1.6 to 2.0V; V
SS
= 0V; T
A
= -40°C to +85°C
The current for 3.3V circuits is sourced at the VBAT pin, except when using an external 3.3V supply
as shown in Figure 5.7.
4.1 Operating Current
Note 4.1 ClockSuspendM bit = 0.
Note 4.2 SessEnd, VbusVld, and IdFloat comparators disabled. STP Interface protection disabled.
