For silicon A0, DCDC_IN voltage domain is 2.9V~3.1V
2.4. SDRAM memory
One 256 Mb, 166MHz SDRAM (MT48LC16M16A2B4-6AIT: G) is used on the EVK Board.
2.5. SD Card Slot
There is a SD card slot(J20) on the MIMXRT1050 EVK Board.J20 is the Micro SD slot for USDHC1
interface. If the developer wants to boot from the SD Card, the boot device switch (SW7) settings should
be: ON, OFF, ON, OFF, as shown in Table 3.
