system's fabric-switched Link Ports A and B, and can be inserted into system or peripheral slots. The cPB-
4612 is keyed for insertion into compatible slots. 
The "CompactPCI" topic in Appendix D contains a link to the PCI Industrial Computer Manufacturers Group. 
1.3.2 Processor 
The cPB-4612 uses the Mobile Pentium M in a micro FCBGA package.  The 1MB or 2MB on-die transfer L2 
cache is integrated with the CPU, eliminating the need for separate components and improving 
performance.  The FCBGA package Pentium M processor also operates with a 400 MHz Processor Side 
Bus for very fast access to memory and data. 
The "Mobile Pentium M (FCBGA Package)" topic in Appendix D contains a link to the datasheet for the 
processor. 
1.3.3 Chipset 
The Intel 855GME chipset consists of two controller hubs.  The 855GME Memory Controller Hub (MCH) 
supports a 400MHz system bus, DDR200/266/333 memory, and an integrated graphics solution w/Intel 
Extreme Graphics 2 technology.  The 6300ESB I/O Controller Hub (ICH4) makes a direct connection to the 
memory for faster access to peripherals. It provides the features and bandwidth required for applied 
computing-usage models.  The following is a list of features of the 855GME chipset: 
•  Designed, validated, and optimized for the Intel Pentium M with NetBurst™ micro-architecture 
using proven and established building blocks  
•  400MHz system bus delivers a high-bandwidth connection between the Intel Pentium M and the 
platform, providing 3x the bandwidth over platforms based on Intel® Pentium® III processors  
•  USB controllers provide high performance peripherals with 480Mbps of bandwidth.  This results 
in a significant increase over previous integrated 1-4 port hubs at 12Mbps 
• Dual 
UARTs 
• Serial 
ATA 
• 64bit/66Mhz 
PCI-X 
bus 
•  32bit/33Mhz PCI bus  
•  Dual Ultra ATA/100 controllers, coupled with the Intel
®
 Application Accelerator - a performance 
software package - support faster IDE transfers to storage devices  
•  The Intel® Application Accelerator software provides additional performance over native ATA 
drivers. The Intel Application Accelerator improves system performance by improving I/O 
transfer rates and enables faster O/S load time resulting in accelerated boot times 
•  Embedded lifecycle support 
The "Intel 855GME Chipset" topic in Appendix D contains a link to information about the chipset. 
1.3.4  PCI-to-PCI Bridge  
The cPB-4612 has a 64bit/66Mhz PCI-X bridge to the CompactPCI backplane.  The bridge will configure 
itself as a transparent bridge when the board is in a system slot, so that the cPB-4612 can be the system 
host.  If the cPB-4612 is placed in a peripheral slot, the bridge configures itself as a non-transparent bridge, 
and will show up as a PCI device to the host.  This allows use of the board in either a system or peripheral 
slot.
