2.1 Introduction

™
® ®
Quadmo747-E6xx is a CPU module, in new Qseven format, based on Intel Atom E6xx series
®
CPU, interfaced to Intel EG20T Platform Control Hub.
This high level of integration allows an extremely reduced consumption of spaces, that is essential
®
for boards with sizes so reduced as for Qseven boards, which offers all functionalities of standard
PC boards in just 70x70mm.
Many CPUs are available for Quadmo747-E6xx module, ranging from 600MHz to 1.6GHz. All
CPU's available have a 512KB L2 cache, and a TDP (Thermal Dissipation Power) between 3.3W
and 4.5W, so that global power consumption of the board can be limited. Moreover, all CPU offer
dual Thread capabilities.
™
®
Intel Atom E6xx CPU series include many features that were usually included in external
Chipsets (Northbridge and Southbridge): an advanced 2D and 3D graphic accelerator, HD Audio
interface, the memory controller, the PCI Express interface (4 lanes x1), one SPI interface, LPC
Bus interface and SM Bus. From CPU's integrated 2D/3D Graphic Media Accelerator, the LVDS
and SDVO interfaces are directly carried out to the golden finger card edge connector.
Communications between CPU and PCH comes through the Hi-Speed PCI Express lane #0
managed directly by the CPU.
The Platform Controller Hub completes the already rich list of features offered by the CPU, making
available two SATA channels, a CAN interface, 6 USB 2.0 Host ports and one USB Client port, one
SDI/O interface, I2C Bus and another SPI interface (different than the one offered by the CPU),
®
which is carried out directly on the Qseven golden finger connector.
The board is completed with up to 2GB DDR2 directly soldered on board, and one SATA Flash
Disk, directly accessible like any standard Hard Disk, with up to 32GB of capacity. The internal
®
SATA Flash Disk is alternative to second SATA Channel carried out on Qseven golden finger.
Interfaced to CPU's PCI Express lane #3, there is a Gigabit Ethernet Controller. It is used this
external GbE controller instead of PCH internal controller in order to offer more bandwidth.
Depending on the version of the board (Commercial or Extreme), the Gigabit Ethernet controller
®
used can be Realtek RTL811E (commercial version) or Intel WG82574IT (Extreme version).
®
Interfacing to the board comes through a single card edge connector, as defined by Qseven
specifications, where are carried out all interfaces previously described. For external interfacing to
standard devices, a carrier board with a 230-pin MXM connector is needed. This board will
implement all the routing of the interface signals to external standard connectors, as well as
integration of other peripherals/devices not already included in Quadmo747-E6xx CPU module.
All CPU of E6xx family are available both in commercial temperature range (0 ÷ 70°C) and
industrial temperature range (-40°C ÷ +85°C). It is possible to have an EXTREME version of the
board, where all the components mounted onboard are certified to work in industrial range,
therefore the board is specifically developed to work in range –40°C ÷ +85°C.
®
For thermal dissipation of the board, according to Qseven specifications, it is contemplated the
use of an application specific heatspreader, that is fixed to the board and get in touch with surfaces
at higher temperature, like CPU core. For better thermal distribution, on top and bottom side of
Quadmo747-E6xx modules there is a metalled strip free of components, opposite to card edge,
which goes in direct contact with the heatspreader, to increment the surface used for thermal
exchange.
Standard heatspreaders/heatsinks for Quadmo747-E6xx module are available from SECO,
however, thermal dissipation need to be specifically studied within the whole system.
