* 512 Mbyte NAND flash
* 16 Mbyte high-speed SPI flash
* SD connector to interface with the SD memory card
Ethernet:
* XFI 10G port
* QSGMII with 4x 1G ports
* Two RGMII ports
PCIe:
* PCIe2 (Lanes C) to mini-PCIe slot
* PCIe3 (Lanes D) to PCIe slot
USB 3.0: two super speed USB 3.0 type A ports
UART: supports two UARTs up to 115200 bps for console
