P R E L I M I N A R Y
2.3 Intel® QM57 Express Chipset
The CP3002 is equipped with the mobile Intel® QM57 Express Chipset, a highly integrated plat-
form controller hub (PCH) with the following features:
• Two x4 or eight x1 PCI Express 2.0 ports operating at 2.5 GT/s (only two x1 PCI Express
ports are used)
• SATA host controller with six ports, 3 Gbit/s data transfer rate and RAID 0/1/5/10 support
• USB 2.0 host interface with up to 14 USB 2.0 ports available (only six ports are used)
• SPI interface support
• Low Pin Count (LPC) interface
• PCI interface, 32-bit/33 MHz
• Power management logic support
• Enhanced DMA controller, interrupt controller, and timer functions
• System Management Bus (SMBus)
• DMI and FDI interfaces to the processor
• Intel® High Definition Audio Interface (not used)
• Analog display port
• Three digital display ports (only one port is used)
• Integrated RTC
2.4 Timer
The CP3002 is equipped with the following timers:
• Real-Time Clock
The Intel® QM57 chipset integrates an MC146818B-compatible real-time clock with 256
Byte CMOS RAM. All CMOS RAM data remain stored in an additional EEPROM device
to prevent data loss.
• Counter/Timer
Three 8254-style counter/timers are included on the CP3002 as defined for the PC/AT.
• The Intel® QM57 chipset integrates eight high-precision event timers.
Note ...
When the CP3002 is populated with 4 GB or 8 GB physical memory and used
with a 32-bit operating system, the CP3002 provides even less memory to
applications than indicated in the table above. In this event, the total memory
available to the applications depends on the system configuration.
Note ...
Only qualified DDR3 ECC SODIMM modules from Kontron are authorized for
use with the CP3002. Replacement of the SODIMM modules by the customer
without authorization from Kontron will void the warranty.
Note ...
To achieve full memory performance, it is recommended to populate both mem-
ory channels.
