What Voltage should NVCC_1P2V be on the SoloLite?

[bjozwiak]

Sounds like the answer is in the question. But the new version of the SoloLite Datasheet (REV3) has confused the situation. On page 21 of the Rev3 datasheet it seems to be tied to the DDR interface voltage. Should this pin (W7; NVCC_1P2V) be tied to the voltage we use for DDR? Or should it be 1.2V?

Also what is the 1.2V power pin used for in the SoloLite? The datasheet is unclear. It looks like it is used for the HSIC interface. It also looks like it can be used for the internal 24MHz Oscillator. DDR?

Hi Bryan

yes,  pin (W7; NVCC_1P2V) may be tied to the voltage you use for DDR

or use the same voltage value from other power source.

I did not fully understand question:

"what is the 1.2V power pin used for in the SoloLite".

Table 73 "13 x 13 mm Functional Contact Assignments"

SoloLite Datasheet (REV3) gives power domains for all pads.

Yes, NVCC_1P2V is used for the HSIC interface, others - not.

Best regards
