The decision to choose a clock source should be taken based on real-time clock use and precision time-out.

Maximum Supply Currents

The numbers shown in Table 11 represent the maximum current consumption possible.

See the i.MX 6SLL Power Consumption Measurement Application Note for more details on typical power

consumption under various use case definitions.

1 The actual maximum current drawn from VDD_HIGH_IN will be as shown plus any additional current drawn from the

VDD_HIGH_CAP outputs, depending upon actual application configuration (for example, NVCC_DRAM_2P5 supplies).

2 The maximum VDD_SNVS_IN current may be higher depending on specific operating configurations, such as

BOOT_MODE[1:0] not equal to 00, or use of the Tamper feature. During initial power on, VDD_SNVS_IN can draw up to 1 mA,

if available. VDD_SNVS_CAP charge time will increase if less than 1 mA is available.

4 The DRAM power consumption is dependent on several factors, such as external signal termination. DRAM power calculators

are typically available from the memory vendors. They take in account factors, such as signal termination.

See the i.MX 6SLL Power Consumption Measurement Application Note or examples of DRAM power consumption during

specific use case scenarios.

NVCC33_IO

N=156

Use maximum IO Equation5

5 General equation for estimated, maximum power consumption of an IO power supply:

Imax = N x C x V x (0.5 x F)

Where:

N—Number of IO pins supplied by the power line

C—Equivalent external capacitive load

V—IO voltage

(0.5 x F)—Data change rate. Up to 0.5 of the clock rate (F)

In this equation, Imax is in Amps, C in Farads, V in Volts, and F in Hertz.

NVCC18_IO

N=156

Use maximum IO Equation5
