Introduction
Product Description
The MB835 motherboard incorporates the Intel® EP80579 Integrated
Processor for embedded computing. The EP80579 System on a Chip
(SoC) is a new generation processor that is cost optimized for a wide
range of applications. EP80579 delivers the balance of a powerful IA-32
processor core, standards-based chipset, and acceleration
/communications-focused I/O capabilities.
The EP80579 SoC integrates features into a single device with memory
controller hubs (IMCH) and I/O controller hubs (IICH). The IMCH has
built-in memory controllers for external memory and the IICH has
standard IA I/O peripheral capabilities.
The MB835’s EP80579 IA-32 core is a derivative of the Intel®
Pentium® M processor. This low power IA-32 core is based on 90-nm
process technology featuring 256-Kbyte L2 cache and 400/533 MHz
quad-pumped internal front-side bus (FSB). With two DDR2 DIMM
sockets on board, the board supports up to 2GB of DDR2 system
memory. It integrates three Gigabit Ethernet MAC interfaces. The MAC
fully implements the IEEE 802.3z, Carrier Sense Multiple Access with
Collision Detection (CSMA/CD) method and physical layer
specifications The GbE features include RGMII/RMII interface to PHY
devices Multi-speed operation 10/100/1000 Mbps.
The main features of the ECX810 board are:
Supports Intel EP80579 processors in 600/1066/1200MHz.
EP80579 built-in USB 2.0 host controller supports 2 ports.
EP80579 built-in SATA controller supports 2 ports.
Two DDR2 SDRAM DIMM, Max. 2GB memory.
Integrated Three Gigabit Ethernet MACs + PHY.
Intel 82574L PCI-E X1 Controller.
2x SATA, 2x USB 2.0, 4x COM, Watchdog timer.
Interface connector for daughter board (ID835/IBP835).
