C3PM / C3RM
The C3PM is a 3U CompactPCI compatible platform based on the Intel ® low power Pentium ® M processor. The Pentium M’s low power consumption ideally equips the C3PM for rugged applications. The C3PM is built with no socketed components and an optional full-board heat sink and wedgelocks for operation in high shock/vibration conditions and extreme temperatures.
The 855GME and 6300ESB chipset supports PCI-X expansion to a dual-port 1000BaseTX Ethernet controller, integrated VGA, two USB 2.0 ports, ATA/100, Serial ATA, and two configurable RS232/422 COM ports. On-board CompactFlash permits single-slot booting. Conventional PC I/O is accessible with industry standard connectors on an optional rear I/O module.
All I/O is routed through the J2 backplane connector.

- Pentium M
- The Intel® Pentium® M processor was designed from the ground up with a new microarchitecture that delivers high performance with low power consumption. With its 90 nm processing technology and 2 MB of L2 advanced transfer cache, the Pentium M offers more performance per Watt. Second-generation Streaming SIMD Extensions (Streaming SIMD Extensions 2) capability adds 144 new instructions, including 128-bit SIMD integer arithmetic and 128-bit SIMD double-precision floating-point operation. The Pentium. The Pentium M also offers a dedicated hardware stack manager that employs sophisticated hardware control for improved stack management, advanced branch prediction capability, and a 400 MHz front side bus to the memory controller hub.
- Chipset and 6300ESB ICH
- The Intel® 855GME Graphics Memory Controller Hub (GMCH) and Intel® 6300ESB I/O Controller Hub (ICH) chipset create an optimized integrated graphics solution with a 400 MHz system bus and integrated 32-bit 3D core at 133 MHz.
- 855GME
- DRAM Controller
The 855GME (GMCH) provides a 266 MHz interface to DDR RAM (72 bits wide with ECC). The C3PM can be populated with 512 MB of total memory respectively. The GMCH system memory architecture is optimized to maintain open pages (up to 16-kB page size) across multiple rows. As a result, up to 16 pages across four rows is supported. To complement this, the GMCH will tend to keep pages open within rows, or will only close a single bank on a page miss.
Graphics Processor
The 855GME also has an advanced integrated graphical display controller. The C3PM has an VGA port out through the J5 connector to the system backplane.
- 6300ESB
- The 6300ESB I/O Controller Hub (ICH) provides most of the C3PM's on-board I/O and it's the C3PM's PCI-X expansion bridge. The ICH is designed as a low-power, high-performance I/O hub that features:
• 64-bit @ 66 MHz PCI-X expansion that is used on the C3PM for the two Ethernet ports available on the C3PM.
• Two USB 2.0 compliant ports that are routed to the J2 connector to the backplane
• Integrated IDE controller supports Ultra 100 DMA Mode Transfers up to 100 MB/sec read cycles and 88.88 MB/sec write cycles for a CompactFlash drive on-board
•Serial ATA providing 150 MB/sec data rates are also routed through J2
• Standard PC functionality like a battery-backed RTC and 256-bytes of CMOS RAM, Power Management Logic, Interrupt Controller, Watchdog Timer, AC'97 CODEC, Integrated 16550 compatible UART's, and multimedia timers based on the 82C54
- Intel 82546EB Dual Gigabit Ethernet Controller
- The C3PM supports two 10/100/1000BaseTX channels that are routed to the J2 . The Intel 82546EB Dual Port Gigabit Ethernet Controller incorporates two full Gigabit Ethernet MAC and PHY layer functions on a single, compact component. Routed from the ICH, the front side data path to the dual Ethernet port controller is a 64-bit PCI-X interface at 66 MHz. The Intel 82546EB offers the following features: 10, 100, and 1000BaseTX support with auto-negotiation; Dual 64KB configurable RX and TX packet FIFOs; 128-bit internal data path architecture for low latency data handling and superior DMA transfer rate performance; Built-in Phyceiver
