Standard Slot Connectors
9.1
SATA Connector
Only one S-ATA
®
2.0 port is available. Serial-ATA
®
connections boost the data rate theoretically up to 300
MB/sec. In addition it changes the parallel interface requiring 40 separate wires to a serial interface requi-
ring only 6 wires. The controller supports the Advanced Host Controller Interface (AHCI).
Note that SATA connector shares the internal SATA port with mSATA connector. If mSATA card is plugged in,
then hardware automatically switches from the SATA connector to the mSATA card socket.
The S-ATA
®
interface is available through the standard L-type connector J28 (7 pins).

Secure Digital and Multimedia Card
The SD/MMC interface uses two standard SD
TM
card sockets as well as an onboard SanDisk
®
16 GByte
embedded flash drive with an e.MMC interface. The controller supports the SD
TM
specification revision 3.0
(implies the SDSC, SDHC and SDXC families) and the MMC specification revision 4.4. The data bus width
accounts 4 bits for the standard sockets and 8 bits for the flash drive, the SD
TM
card transfer rate can be up
to 50 MHz and MMC rate up to 52 MHz. The onboard SanDisk
®
16 GByte embedded flash drive is bootable.
The SD
TM
card sockets are named J19 and J20 (9 pins).
