User Guide • SC3-LARGO • CompactPCI®Serial CPU Board • Intel®CoreTM 5xxx Processor
Overview
The SC3-LARGO is a rich featured high
performance 4HP/3U CompactPCI®Serial CPU
board, equipped with a 5th generation Intel®
Core™ mobile processor (Broadwell H quad-
core). The SC3-LARGO front panel is provided
with two Gigabit Ethernet jacks, two USB 3.0
receptacles, and two mDP connectors,
compliant with the DisplayPort 1.2 standard for
Multi-Stream-Transport (MST). Local expansion
mezzanine cards are available for additional I/O.
The SC3-LARGO is equipped with up to 24GB
Low Power RAM with ECC support. up to 8GB
memory-down are provided for rugged
applications, and another 16GB are available via
the DDR3L ECC SO-DIMM socket. The on-board
SATA 6G RAID controller allows for powerful
mass storage solutions via the CompactPCI®
Serial backplane. Low profile SSD mezzanine
modules are available as on-board storage
solution, in addition.
While mechanically compliant to CompactPCI®
Classic, CompactPCI®Serial (PICMG®CPCIS.0)
defines a completely new card slot, based on
PCI Express®, SATA, Gigabit Ethernet and USB
serial data lines. Up to 6 high-speed backplane
connectors P1 - P6 are provided on a system
slot controller such as the SC3-LARGO, which
can be considered as a root hub with respect to
most signal lines. A passive backplane is used
for distribution of a defined subset of I/O
channels from the system slot to each of up to
eight peripheral slots in a CompactPCI®Serial
system.
Most CompactPCI®Serial peripheral slot cards
require only the backplane connector P1, which
comprises PCIe, SATA and USB signals, resulting
in a concise and inexpensive peripheral board
design. More powerful peripheral cards profit
from so called Fat Pipe slots (PCIe x 8).
The SC3-LARGO is a native CompactPCI®Serial
CPU card, suitable for usage in a pure CPCI
Serial environment. Due to its generous
backplane capabilities (22 x PCI Express®lanes,
6 x USB2, 2 x USB3, 7 x SATA/RAID, 2 x GbE),
very powerful industrial systems can be built.
The SC3-LARGO is equipped with a set of high-
speed 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 such
as RS-232, and additional PCI Express®based
I/O controllers such as SATA, USB 3.0 and
Gigabit Ethernet, and also a third video output.
Most mezzanine side cards can accommodate
in addition a 2.5-inch drive. Typically, the
SC3-LARGO and the related side card would
come as a readily assembled 8HP unit. As an
alternate, MicroSATA or mSATA SSD based low
profile mezzanine mass-storage modules are
available that fit into the SC3-LARGO 4HP
envelope.
