2 CMA34CR cpuModule BDM-610000083 Rev L
CMA34CR cpuModules
RTD's CMA34CR cpuModule represents the latest in low power and high performance PCI Express embedded
controllers. Based on a 3rd Generation Intel(r) Core i7 (tm) processor and chipset, the CMA34CR is offered with
a high performance 1.5 GHz Single core processor, a1.7 GHz Dual-Core processor or a 2.1 GHz Quad-Core
processor. Each comes with a complete DDR3 memory interface supporting up to 8GB and operating at up to
1600 MT/s. All memory chips are soldered directly onto the board.
A Serial-ATA (SATA) controller provides a fast connection to the hard drives. Network connectivity is provided
by two integrated 10/100/1000 Mbps Ethernet controllers. High-speed peripheral connections include USB 2.0,
with up to 480 Mb/sec data throughput. Four additional SATA links and USB 3.0 connections permit further
expandability on the top and bottom-side PCIe/104 Type 2 connectors. Also provided are 8 x1 PCI Express Gen
2.0 links, four to the top connector and four to the bottom connector. Other features include two
RS-232/422/485 COM ports and Advanced Digital I/O (aDIO).
RTD has gone the extra mile to include additional advanced features for maximum flexibility. These include an
onboard SATA surface-mount flash drive with a standard SATA interface. An Advanced Watchdog Timer is
provided that can generate an interrupt or reset when the timer expires. The CMA34CR is also available in a
rugged, fanless IDAN enclosure.

You can easily customize the cpuModule by stacking PCI/104-Express or PCIe/104 modules such as video
controllers, Digital Signal Processors, drive carriers, LAN controllers, or analog and digital data acquisition
modules. Stacking modules onto the cpuModule avoids expensive installations of backplanes and card cages,
and preserves the module's compactness.

BDM-610000083 Rev L Chapter 1: Introduction 3
The cpuModule uses the RTD Enhanced BIOS. Drivers in the BIOS allow booting from hard disk, UEFI shell, or
PXE Ethernet, thus enabling the system to be used with traditional disk drives or nonmechanical drives. Boot
from USB devices and network are also supported.
The cpuModule and BIOS are also compatible with any real-time operating systems for PC compatible
computers, although these may require creation of custom drivers to use the aDIO and watchdog timer.
Intel Turbo Boost
The Intel Turbo Boost Technology is a feature integrated into the dual and quad core i7 processors. This allows
the processor to run faster than its rated operating core and/or graphics rendering clock frequency in the right
circumstances. There must be sufficient power headroom and the cpuModule must be within all thermal and
current limits. This feature is designed to increase the performance of both multi-threaded and single-threaded
work loads. The support for Turbo mode occurs when the processor can use the thermal capacity associated
with the package and run at higher power levels for short durations. Increasing system responsiveness for short,
burst usage conditions.
aDIO
RTD’s exclusive aDIO™ is 12 digital bits configured as 8 bit-direction programmable and 4-bit port-direction
programmable I/O, plus 2 strobe inputs giving you any combination of inputs and outputs. Match, event, and
strobe interrupt modes mean no more wasting valuable processor time polling digital inputs. Interrupts are
generated when the 8 bit-direction programmable digital inputs match a pattern or on any value change event.
Bit masking allows selecting any subgroup of eight bits. The strobe input latches data into the bit-programmable
port and generates an interrupt.
Note Intel Turbo Boost is not available on the Single Core Celeron processor.

Ordering Information
The CMA34CR cpuModule is available with a selection of processors and memory sizes. The cpuModule can also
be purchased as part of an Intelligent Data Acquisition Node (IDAN™) building block, which consists of the
cpuModule and a milled aluminum IDAN frame. The IDAN building block can be used in just about any
combination with other IDAN building blocks to create a simple but rugged PC/104 stack. Refer to Appendix C,
IDAN™ Dimensions and Pinout, for more information. The CMA34CR cpuModule can also be purchased as part
of a custom-built RTD HiDAN™ or HiDANplus High Reliability Intelligent Data Acquisition Node. Contact RTD
for more information on its high reliability PC/104 systems.
CMA34CR Model Options
The basic cpuModule model options are shown below. Refer to the RTD website (www.rtd.com) for more
detailed ordering information and any new variations that may be available. Each CPU has the option to go up
to 8GB DDR3-SDRAM, and up to a 32 GByte onboard SATA flash drive.
