I, Power 5V
Input voltage to drive the internal USB LDO.
Important Note: It is better to provide the
always ON 5V power to this pin for USB block
to work properly in i.MX6UL/i.MX6ULL CPU.
¹ Important Note: These signals are also used for i.MX6UL/i.MX6ULL CPU bootstrap setting on SOM and so no external
loads or pull-up/pull-down resistors to be connected to these pins which will change the boot configuration.
² Termination value is mentioned based on NAND flash as boot media. If boot media is changed, termination value also
may change.
