The CP6500-V, a Value Line CompactPCI board in 6U height, comes with a 1 GHz or 400 MHz (LV/ULV version) Intel. Celeron. processor and is designed for price-sensitive applications. The 400 MHz version works with passive cooling alone. The inexpensive 144 pin SODIMM RAM of the board is scalable at three levels, with 128 MB, 256 MB, or 512 MB SDRAM. In addition, the hot swap capable CPU board offers various interfaces, including four USB 2.0 ports as well as two Fast Ethernet interfaces, which are either accessible via the front panel or, alternatively, realized through the backplane in accordance with PICMG 2.16, enabling wireless switched fabrics. There are also two serial ports, plus the usual keyboard, floppy drive and graphics connections (VGA CRT with a resolution of 1600 x 1200 pixels).Two EIDE ports facilitate the connection of mass-storage devices; one of these interfaces is designed for an on-board HDD. In addition, the CPU board includes a CompactFlash socket. Via a 32 bit/33 MHz PMC slot with rear I/O support, the CP6500-V can be further expanded through mezzanine cards as required. Additional I/O can be connected through an LPC interface, or via rear I/O or CompactPCI extension components.The CP6500-V works in the system slot as well as in the peripheral slot. In the former, it will communicate with all peripheral boards via CompactPCI or Ethernet over backplane in accordance with PICMG 2.16; in the latter, the communication channel is Ethernet over backplane.
