Product Description
The CoreModule 720 SBC is a highly integrated, high performance, Intel  Atom™ E6XXT processor
based system, compatible with the PC/104 standard. This rugged and high quality single-board system
contains all the component subsystems of an ATX motherboard, plus the equivalent of several PCI
expansion boards.
The Intel Atom E6XXT series CPUs integrate processor cores with Graphics and Memory Controller Hubs
(GMCHs), providing low-power, high-performance processors, memory controllers for up to 2GB of DDR2
on-board memory, and graphics controllers which provide LVDS and SDVO signals for most LCD video
panels and CRT monitors.
The EG20T PCH (Platform Controller Hub) provides the I/O hub for a range of common interfaces
including six USB ports, four serial ports, and two SATA ports, as well as embedded interfaces for CAN,
GPIO, I2C, and SDIO. The CoreModule 720 provides a Solid State Drive through the SATA1 port and an
SD memory card socket through the SDIO port. The PCH connects to the CPU through the PCIe Port0, and
a Gigabit Ethernet controller connects to the CPU through PCIe Port2.
The CoreModule 720 can be expanded through the LPC and PCIe expansion buses using the PC/104 and
PC/104-Plus connectors for additional system functions. These buses offer compact, self-stacking, modular
expandability. The PC/104 bus is an embedded system version of the signal set provided on a desktop PC’s
ISA bus. The PC/104-Plus bus includes this signal set plus additional signals implementing a PCI bus,
available on a 120-pin (4 rows of 30 pins) PCI expansion bus connector. This PCI bus operates at a clock
speed of up to 66MHz, and the ISA bus operates at 8MHz.
The CoreModule 720 is particularly well suited to either embedded or portable applications and meets the
size, power consumption, temperature range, quality, and reliability demands of embedded system
applications. It can be stacked with ADLINK MiniModules™ or other PC/104-compliant expansion
modules, or it can be used as a powerful computing engine. The CoreModule 720 requires a single +5V AT
power source.
