IVIN_3V3
Sleep
(1)
VIN_3V3 = VDDIO = 3.45 V, VBUS = 0,
PPCABLE = 0; 100-kHz oscillator running
58 µA
Idle
(2)
VIN_3V3 = VDDIO = 3.45 V, VBUS=0, PPCABLE
= 0; 100-kHz oscillator running,
48-MHz oscillator running
1.66 mA
Active
(3)
VIN_3V3 = VDDIO = 3.45 V, VBUS = 0,
PPCABLE = 0; 100-kHz Oscillator running,
48-MHz oscillator running
5.64 mA
(1) Sleep is defined as Type-C cable detect activated as DFP or UFP, internal power management and supervisory functions active.
(2) Idle is defined as Type-C cable detect activated as DFP or UFP, internal power management and supervisory functions active, and a
selectable clock to the digital core of 3 MHz or 4 MHz.
(3) Active is defined as Type-C cable detect activated as DFP or UFP, internal power management and supervisory functions active, all
core functionality active, and the digital core is clocked at 12 MHz.
(4) Application code can result in other power consumption measurements by adjusting enabled circuitry and clock rates. Application code
also provisions the wake=up mechanisms (for example, I
2
C activity and GPIO activity).
