Motorola’s highest performance VMEbus single-board computer
The MVME5500 is the latest flagship of the Motorola VME product line, enabling even higher levels of performance in a single VMEbus slot. The MVME5500 utilizes the latest MPC7455 processor running at speeds of 1 GHz and beyond, which is ideal for data intensive applications.
The MVME5500 provides more than just faster processor performance; it provides balanced performance from the processor, memory, local buses, and I/O subsystems. The powerful Marvell Discovery system controller, with support for a 133 MHz host bus and a 133 MHz SDRAM memory bus, is well matched to the high-speed processor. To match the system I/O to the outstanding processor performance, the MVME5500 provides dual 64-bit, 33/66 MHz PCI buses. Each PCI bus has a PMC site supporting cards running at 33 or 66 MHz. The Universe II VME interface and PMCspan connector are isolated from the PMC sites on a dedicated 33 MHz PCI bus segment, so that both PMC sites are capable of 66 MHz operation. The MVME5500 also offers a Gigabit Ethernet interface, a 10/100BaseTX Ethernet interface, and two serial ports. All of this adds up to a set of well-balanced, high-performance subsystems for unparalleled performance.
The MVME5500 series is designed to meet the needs of OEMs servicing the defense and aerospace, industrial automation, and medical imaging market segments. Customers looking for a "technology refresh" for their application while maintaining backward compatibility with their existing VMEbus infrastructure can upgrade to the MVME5500 series and take advantage of the enhanced performance features.

Backward Compatibility
The MVME5500 continues the direction that Motorola started with the MVME5100 series of providing a migration path from Motorola’s embedded controllers and single-board computers (SBCs) to a single platform. This migration path enables OEMs to support varying I/O requirements with the same base platform, simplifying part number maintenance, technical expertise requirements, and sparing.
The MVME5500 series offers customers a migration path from the MVME2300, MVME2400, MVME2600, MVME2700, and MVME5100 boards to allow them to take advantage of features such as the MPC7455 processor, Gigabit Ethernet, and 33/66 MHz PMC sites.
P2 I/O Modes
Like the MVME5100 series, the MVME5500 series supports two, jumper-configurable P2 I/O modes: PMC mode and IPMC mode. PMC mode is backward compatible with the MVME2300/MVME2400 and MVME5100 in PMC mode. In PMC mode, 64 pins from PMC Slot 1 and 46 pins from PMC Slot 2 are available on P2 for PMC rear I/O. In IPMC mode, the MVME5500 series supports legacy MVME761 or MVME712M I/O modules (with limited PMC I/O) when an IPMC761 or IPMC712 PMC card is populated in PMC Slot 1. In this configuration, PMC Slot 2 contains some signals that are reserved for extended SCSI.
IPMC Modules
The IPMC761 and IPMC712 are optional add-on PMC modules that provide backward compatibility with previous generation Motorola products (such as MVME2600, MVME2700, and MVME5100 in IPMC mode) using the MVME761 or MVME712M transition module. IPMC modules provide rear I/O support for the following:
• One single-ended Ultra Wide SCSI port
• One parallel port
• Four serial ports (two or three async and one or two sync/async, depending on module)
With this PMC card configuration, one PMC slot is still available, providing support for OEM product customization.
Transition Modules
MVME761 The MVME761 transition module provides industry-standard connector access to the IEEE 1284 parallel port, a 10BaseT or 100BaseT port via an RJ-45 connector, two DB-9 connectors providing access to the asynchronous serial ports configured as EIA-574 DTE, and two HD-26 connectors providing access to the sync/async serial ports. These serial ports, labeled as Serial 3 and Serial 4 on the faceplate of the MVME761, are individually user-configurable as EIA-232, EIA-530, V.35, or X.21 DCE or DTE via the installation of Motorola serial interface modules (SIMs).
A P2 adapter provides interface module signals to the MVME761 transition module. The 3-row P2 adapter can be used for 8-bit SCSI. A 5-row P2 adapter supports 16-bit SCSI and PMC I/O.
MVME712M The MVME712M transition module provides industry-standard connector access to the Centronics parallel port, a narrow SCSI port, and four DB-25 connectors providing access to the asynchronous/synchronous serial ports jumper configurable as EIA-232 DCE or DTE. A P2 adapter provides interface signals to the MVME712M transition module. The 3-row P2 adapter can be used for 8-bit SCSI.
