Caution!
•
The NXP® Semiconductor i.MX 6 is a multi-voltage operated microcontroller and as such
special attention should be paid to the interface voltage levels to avoid unintentional
damage to the microcontroller and other on-board components. Please refer to the
NXP
Semiconductor i.MX 6 Reference Manual for details on the functions and features of
controller signals and port pins.
•
As some of the signals which are brought out on the phyCORE-Connector are used to
configure the boot mode for specific boot options, please make sure that these signals
are not driven by any device on the baseboard during reset. The signals which may
affect the boot configuration are shown in
Table 9 .
•
It is mandatory to avoid voltages at the IO pins of the phyCORE-i.MX 6 which are
sourced from the supply voltage of peripheral devices attached to the SOM during
power-up, or power–down. These voltages can cause a current flow into the controller
especially if peripheral devices attached to the interfaces of the i.MX 6 are supposed to
be powered while the phyCORE-i.MX 6 is in suspend mode, or turned off. To avoid this
bus switches either supplied by VDD_3V3_LOGIC on the phyCORE side, or having their
output enable to the SOM controlled by the X_3V3_GOOD signal (
section 4.3 ) must be
used.
