NAND Flash Schematic
The following memory part numbers are recommended:
4.2.6
SD/MMC Interface
The SAMA5D3 Xplained board features two high-speed Multimedia Card Interfaces (MCI).
The first interface is used as an 8-bit interface (MCI0), connected to a SD/MMC card slot (J10) located on
the bottom side of the PCB.
The second interface is used as a 4-bit interface (MCI1), connected to an optional Micro-SD card connector
(J11) located on the top side of the PCB.
The MCI0 SD card power line is enabled by default. It is PIO-controlled through a MOSFET transistor.
Note:
The power source is VCC (3.3 volts).
4.2.6.1 J10 SD Card Slot
When a card is inserted into the SD/MMC connector, the Card Detect pin (PE0) is tied to ground.
