digital I/O supplies (NVCC_xxxx) in Standby Mode

[mohsengh]

Hello Dears

I'm trying to design an embedded system by i.MX6solox. I need Low power Mode like standby.

I use PF0200 as external PMIC.

Can i turn-off digital I/O supplies and associated peripherals in standby Mode that is connected to SW2 buck regulator of PMIC?

below highlighted text confused me (IMX6XAEC).

Thanks in advance for any Information.

Hello Mohsen Gh,

The digital supplies must be powered as described on table 10-1 (Power Modes) of the i.MX6SX Reference Manual. All digital IO supplies not referred on this table must remain powered.

I hope this information helps!

Hello gusarambula 

Thanks for your reply

But my question is about NVCC_xxx that is not shown (or may I can't see) in Table 10-1.

Figure 10-12 shows an example of external power supply.

my question is :

Can i turn-off NVCC_xxx supplies in STOP mode to remove current consumption?

thanks

Hello Mohsen Gh,

My apologies! The NVCC_XXX supplies must be powered on at all times unless explicitly said otherwise on the table. This because of the GPIO Pads that must be available for wake up interruptions.

I hope this clarifies your concerns.
