RPM

VMEbus Conduction-cooled Pentium-M Single Board Computer



Features

  • Intel® Pentium® M Processor:
  • Single-slot VMEbus operation with an on-board compactFlash disk for bootable mass storage
  • 855GME and 6300ESB Chipset
  • -40°/+85°C operation with 1.4 GHz Pentium M

The RPM is a rugged conduction-cooled VMEbus (and VME64) compatible platform based on the Intel® low-power Pentium® M (Dothan) processor. The RPM takes advantage of the Pentium M's low-power consumption as a rugged Single Board Computer (SBC) and it is an IEEE 1101.2-compliant, conduction-cooled VMEbus module with wedge locks and a full-board heat sink for high shock/vibration environments and temperature extremes.

The RPM is the same board design as the convection-cooled DPM . The DPM typically uses front panel I/O routing but can be provided with identical I/O routing as the RPM for application development in a standard VMEbus chassis.

The 855GME Graphics Memory Controller Hub (GMCH) and 6300ESB I/O Controller Hub (ICH) chipset supports
PCI-X expansion, integrated VGA/DVO interface, USB 2.0, ATA/100, and Serial ATA (SATA). Two USB 2.0 ports, a COM port and IDE are all accessible from the rear P2 connector. SVGA and Digital Vido Output (DVO), dual 10/100/1000BaseT (VITA 31.1 compatible), dual SATA, and LPC bus are routed to the optional P0 connector. On-board CompactFlash permits single-slot booting. One PMC-X site is provided for additional I/O expansion.

The RPM meets an operating temperature range of -40°/85° C with it's standard 1.4 GHz Pentium M processor.

The RPM was design for compliance with MIL-Std-810F. Options include conformal coating.

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 C
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 RPM can be populated with one or two banks of DRAM for 512 MB or 1 GB 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 RPM routes the DVO and analog graphics to P2
6300ESB
The 6300ESB I/O Controller Hub (ICH) provides most of the RPM's on-board I/O and it's the RPM'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 RPM for the on-board PMC-X slot, the three Ethernet ports available on the RPM, and for the Universe IID PCI/VMEbus bridge
· Two USB 2.0 compliant ports routed to the P2 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 and a primary IDE port that is routed through P2 to the RPMPTB
· Two Serial ATA ports providing 150 MB/sec data rates are routed through P0
· 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 DHC supports two 10/100/1000BaseTX channels that are routed to the P0 connector in compliance with the Vita 31.1 Specification for backplane fabric switching. 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 64 bits 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.
