SDIO/MMC socket
An SDIO socket is provided on the ISIS using the CPU module 4 bit wide access port 1.
The SDIO card interface offers great flexibility, including the ability to use the SD socket
for data storage and I/O cards such as Bluetooth and WiFi. The SDIO/MMC controller
supports MMC4.0 and SDIO1.1 specifications.
MMC 4.0 transfer rates can be up to 48MHz; SDIO 1.1 supports transfer rates of up to
24MHz. The US15W SCH SDIO/MMC controller only supports flash cards using byte
addressing limiting the maximum memory density to 2GB. Sector based addressing is
not supported.
Graphics support
The ISIS development kit supports dual independent pipe for multiple display modes on
two outputs:
•
24 bit LVDS.
•
VGA.
The two display outputs can be configured in a number of display modes, to allow for
independent display timings and extended desktop/multi-monitor operating modes.
The ISIS development kit supports Single, Twin, Clone and Extended display
configuration modes.
Audio support
The ISIS supports an Intel High Definition Audio interface. The HD Audio digital bus is
decoded by the ISIS-HDA board, supporting 5.1 surround sound on standard 3.5mm
stereo jacks. See
ISIS-HDA board , page 24 for more information.
USB support
There are four user USB 2.0 high-speed root ports (0/1/4/5) accessible on USB A
connectors located on the ISIS-Breakout board. USB 2.0 allows data transfers up to 480
MB/s.
Ethernet
One 10/100 Ethernet RJ45 socket is available on the ISIS-Breakout board. The Intel
82551IT controller supports MDI/MDI-X feature, enabling auto-correction of incorrect
cabling with respect to cross-over versus straight-through cables.
Link and Activity LED’s are built in the RJ45 socket and indicate the link state and
transfer activity of the ISIS over the network.
