16 CMA34CR cpuModule BDM-610000083 Rev L
Migrating to RTD’s Intel Core i7 cpuModules
When migrating to RTD’s Intel Core i7 cpuModules, there are several differences from preceding cpuModule
product families of which the user should be aware.
Power Differences
The Core i7 cpuModule requires both +12V and +5V for operation, whereas previous cpuModules only required
+5V.
Connector Pinout & Function Differences
The newer Intel Core i7 cpuModules have several connector-related differences, which are summarized below.
Complete information about the connectors on the CMA34CR can be found in Chapter 3,
Connecting the
cpuModule .
New I/O Connectors
The CMA34CR cpuModule introduces a new I/O connector that was not present on previous RTD cpuModules:
•
DisplayPort (CN4)
– Provides video and audio output
– Unlike legacy LVDS and flat panel connectors which needed to have their BIOS pre-configured
to a specific manufacturer’s flat panel parameters, the DisplayPort connector is compatible with
any display that has a DisplayPort interface.
•
SATA Connector (CN15)
– Provides access to the data segment of one standard SATA port
Connector Differences
While some connectors on the CMA34CR have identical pinouts as on previous cpuModule generations, the
features of the connector are sometimes different. Other connectors have entirely different pinouts than those
on previous cpuModule generations. One important change is this cpuModule requires both +12V and +5V to
operate. Connectors with pinout and feature differences include:
•
Auxiliary Power Connector (CN3)
– 12 pins (unlike the 10-pin connector on RTD Core 2 Duo cpuModules)
– Requires both +5V and +12V inputs (5V only auxiliary power connectors found on all
previous RTD cpuModule generations)
– The Auxiliary Power Connector excludes ATX power signaling. The ATX power signals are
provided on the PCIe/104 Type 2 bus connectors.
•
Utility Port 2.0 (CN5)
– Replaces the legacy Utility Port multi-function connector
– Replaces the PS/2 Mouse and Keyboard connections with one USB 2.0 port
– The pinout of the Utility Port 2.0 is not compatible with previous generations of RTD
cpuModules.
•
COM Ports (CN7 and CN8)
– Connector CN7 can be configured to output Serial POST codes out of the TXD pin when in
single RS-232 mode (unlike RTD Core 2 Duo cpuModules, where the DTR pin was configured
for serial POST code output on the second port of CN7 in dual-port mode). For more
information, refer to
Serial Power-On-Self-Test (POST) Code Output on page 72.
