The Advantech PCE-5120G2-00A2E is a full-size industrial single board computer built on the Intel 945G chipset with ICH7R Southbridge. It supports Intel Core 2 Duo, Pentium D, Pentium 4, and Celeron D processors via the LGA775 socket, with FSB speeds of 1066/800/533 MHz and maximum CPU speeds up to 2.66 GHz for Core 2 Duo. The platform delivers dual-channel DDR2 memory support up to 4 GB, integrated Intel Graphics Media Accelerator 950 with up to 224 MB shared VRAM, and extensive I/O connectivity across four SATA II channels (300 MB/s each), one EIDE channel, dual Gigabit Ethernet ports, eight USB 2.0 ports, and four RS-232 serial ports. Expansion capabilities include one PCIe x16 slot, four PCIe x1 links, and four 32-bit/33 MHz PCI masters to backplane, plus one optional PCI expansion slot. The board integrates RAID 0/1/5/10 support, programmable watchdog timer with intervals from 1 to 256 seconds, and CRT video output at up to 2048 x 1536 @ 75 Hz. Design emphasis on thermal management and component redundancy ensures reliable operation across industrial deployment scenarios.
