PF0100

Functional Block Requirements and Behaviors

Power Generation

Figure 9 shows a simplified power map with various recommended options to supply the different block within the PF0100, as

well as the typical application voltage domain on the i.MX6X processor. Note that each application power tree is dependent upon

the system’s voltage and current requirements, therefore a proper input voltage should be selected for the regulators.

The minimum operating voltage for the main VIN supply is 2.8 V, for lower voltages proper operation is not guaranteed. However

at initial power up, the input voltage must surpass the rising UVDET threshold before proper operation is guaranteed. Refer to

the representative tables and text specifying each supply for information on performance metrics and operating ranges. Table 27

summarizes the UVDET thresholds.
