Product Overview
This product is a single board conforming to the VME bus (IEEE 1014-1987) with a 6U-Eurocard form factor. The CPU section employs an Intel ULV Celeron (650 MHz), with Intel 815E (Memory Control Hub) and ICH2 (I/O Control Hub) chipsets. Main memory includes onboard 256 Mbyte SDRAM, with one 144-pin SO-DIMM socket for expansion (maximum 256 Mbyte). L2 cache is 256 Kbyte (CPU integrated).

Functional Characteristics
The board supports booting from five device types: CompactFlash, FDD, IDE (Secondary), USB-FDD, and USB-CDROM. The RS-232C interfaces (COM1, COM2) can be configured as DTE (straight connection) or DCE (cross connection) via jumper settings. P2 connector rows A and C provide IDE (Secondary) and FDD interfaces, connectable to hard disk and floppy disk drives through connector conversion adapters.
Application Scenarios
Industrial embedded computing, factory automation, semiconductor manufacturing equipment, and measurement and control systems requiring VMEbus architecture.
