MOTOROLA MVME5100 series single-board computer

product description:

The MVME5100 Series is the flagship of the Motorola PowerPlus II VME Architecture line, enabling supercomputing levels of performance in a single VMEbus slot. Based on an integrated PCI bridge-memory controller ASIC designed by Motorola Computer Group, PowerPlus II takes memory performance to new levels with 582MB/s memory read bandwidth and 640MB/s burst write bandwidth. Plus, PowerPlus II Architecture supports full PCI throughput of 264MB/s without starving the processor from its memory.
The extended temperature versions of the MVME5100 Series offer hardware and software compatible products to enhance the existing MVME5100 product. The new versions operate at extended temperature ranges of –20° to 71° C vs. 0° to 55° C for the already existing commercial versions. The temperature range is advantageous to OEMs that require extended operating temperatures for their equipment.
The MVME5100 is designed to meet the needs of OEMs servicing the defense and aerospace, industrial automation and medical market segments.

The powerful Marvell system controller, with support for a 133 MHz host bus and a 133 MHz SDRAM memory bus, is well matched to the high speed processor. To match the system I/O to the outstanding processor performance, the MVME5500 provides dual 64-bit, 33/66 MHz PCI buses. Each PCI bus has a PMC site supporting cards running at 33 or 66 MHz. The Universe II VME interface and PMCspan connector are isolated from the PMC sites on a dedicated 33 MHz PCI bus segment so that both PMC sites are capable of 66 MHz operation.
