Mobile Applications
Qseven
®
is unlike previous Computer-On-
Modules (COM) standards due to its primary focus
being directed towards mobile and ultra mobile
applications. It defines fast serial differential
interfaces such as PCI Express and Serial ATA but
omits support for legacy interfaces like EIDE and
PCI in order to provide ideal support for today as
well as future CPU's and chipsets.
Low Power
Qseven
®
is defined for a maximum power
consumption of 12 Watt operated by a single 5
Volt DC power and provides all additional signals
for battery management. This simple power
requirements allow for small mobile solutions
powered by compact two cell batteries.
Connector
Unlike most previous module standards, Qseven
®
does not require an expensive board-to-board
connector. Instead, it utilizes a very affordable
MXM card slot with 230 pins in a 0.5 mm
configuration. This slot is already being used
for graphics cards in laptop computers, so it
is capable of the high speed PEG (PCI Express
Graphics) data transfers.
Legacy Free
Qseven
®
is a legacy free standard and only
focused on high speed serial interfaces.
Compact Size
The module's dimensions are 70x70mm² only.
This means it can be easily integrated into size
constricted systems.
Graphics Interfaces
The video interfaces have been designed with
increased flexibility. A total of four different output
possibilities are defined. Direct control of a flat
panel display via 2x24 Bit LVDS (Low Voltage
Differential Signal) with DisplayID and EPI panel
detection. The physical signals the SDVO port are
shared with DisplayPort and TDMS.
SDIO
When utilizing the SDIO interfaces, rugged and
cheap SD-Cards can be used as bulk memory.
Qseven
®
defines an 8 Bit SDIO interface that is
capable of a maximum data transfer rate of 52
MByte/s. The Secure Digital standard also enables
other applications such as WLAN, Bluetooth, RFID
etc. while using the same card format.
PCI Express
Qseven
®
offers up to 4 PCI Express™ x1 lanes. This
allows the customer to equip their embedded
PC application with the next generation of PC
performance.
Software API
Qseven
®
embedded computer modules are
equipped with a common software API for
industrial applications such as Watchdog Timer,
I²C Bus, LCD brightness control, BIOS user storage
area and the reading of system temperatures.
Qseven
®
modules from different manufacturers
can thus be easily exchanged without
modifications to hardware or software.
