System Architecture
The most up-to-date system architecture of the SBC-845D-VEA includes two main Intel chips: the
845D chipset and the 82801BA ICH2. The Intel 845D chipset supports Pentium-4 processors,
DDR-SDRAM, and 2D/3D graphic display. The 82801BA ICH2 supports a PCI bus interface, APM,
ACPI-compliant power management, USB port, SMBus communication, and Ultra DMA/33/66/
100 IDE Master, and a Fast Ethernet controller. The W83627HF (I/O Controller) controls the PS/2
Keyboard/Mouse, UARTs, FDC, Hardware Monitor, Parallel, Watchdog Timer and Infrared
interface.
The special pin configuration of the CPU socket utilizes a total of 478 pins. This new generation
CPU provides better performance to many applications.
The PCI-to-ISA bridge supports a standard 16-bit ISA bus interface which is applied for all slower
I/O operations. The SBC-845D-VEA supports DiskOnChip (DOC) for M-systems Flash disk.
The onboard PCI Fast Ethernet interface is accessible via RJ-45 ports and supports 10/100bps
data transfer rates. The onboard 68-pin PCI connector supports additional daughterboards for
further system extension.
