CompactPCI© PlusI/O CPU Card • 4th Generation Intel® Core™ Processor (Haswell)

The PC4-PRESTO is a rich featured high performance 4HP/3U CompactPCI® PlusIO CPU board, equipped with a 4th Generation Intel® Core™ mobile processor (Haswell dual- or quad-core). The PC4-PRESTO front panel is provided with two Gigabit Ethernet jacks, two USB 3.0 receptacles, and two Mini DisplayPort connectors, compliant with the DisplayPort 1.2 standard for Multi-Stream-Transport (MST). Local expansion mezzanine boards (side cards) are available for additional front panel and/or rear I/O, resulting in an 8HP front panel width assembly unit. The PC4-PRESTO is equipped with up to 16GB RAM with ECC support. 8GB memory-down are
provided for rugged applications, and another 8GB are available via the DDR3 ECC SO-DIMM socket. Low profile SSD mezzanine modules are available as on-board mass storage solution, maintaining the 4HP front panel width. The PC4-PRESTO backplane connectors comply with the PICMG® CompactPCI® PlusIO system slot specification, via J2 suitable for a rear I/O module or hybrid CompactPCI® Serial system. The PC4-PRESTO is backwards compatible to classic CompactPCI® systems. The PC4-PRESTO is equipped with a set of local expansion interface connectors, which can be optionally used to attach a mezzanine side board. A variety of expansion cards is available, e.g. providing legacy I/O and additional PCI Express® based I/O controllers such as SATA, USB 3.0 and Gigabit Ethernet, or a third video output. Most mezzanine side cards can accommodate in addition a 2.5-inch drive. Typically, the PC4-PRESTO and the related side card would come as a readily assembled 8HP unit. As an alternate, low profile Flash based mezzanine storage modules are available that fit on the PC4-PRESTO while maintaining the 4HP profile. The C48-M2 module e.g. is equipped with two fast M.2 SATA Solid State Drives (SSD), which is suitable for installation of any popular operating system.
