between this voltage and 3.3V_IO must not exceed 300mV.
This constraint is automatically satisfied if
● one of the following ordering codes is used: DA p l r n c 0 t s, DA
● the same voltage rail is used to power AXE ULite SOM and
Since powering is strictly related to reset signals, reading of
highly recommended.
For information about power consumption, please refer to
7.1 Power Supply Unit (PSU) and recommended power-up
sequence
Implementing correct power-up sequence for i.MX6UL processors is not
a trivial task because several power rails are involved. AXEL ULite SOM
simplifies this task by embedding all the needed circuitry. The following
picture shows a simplified block diagram of PSU/voltage monitoring
circuitry:
