向后兼容性
MVME5500延续了SMART EC启动的方向
MVME5100系列提供了从
智能EC的嵌入式控制器和单板计算机
（SBCs）到单个平台。此迁移路径使OEM能够：
使用相同的基础平台支持不同的I/O需求，
简化零件号维护、技术专业知识
要求和备用。
MVME5500系列为客户提供了从
MVME2300、MVME2400、MVME2600、MVME2700和
MVME5100板，使其能够利用功能
例如MPC7455处理器、千兆以太网和双总线
独立于33/66 MHz PMC站点。

of our VME product line that enables higher levels of performance in a single VMEbus slot ƒ MPC7457 PowerPC® processor at 1GHz ƒ 512 KB of on-chip L2 cache and 2MB of L3 cache ƒ AltiVec coprocessor for high-performance computational applications ƒ Two banks of soldered flash memory (32MB and 8MB) ƒ Dual independent 64-bit PCI buses and PMC sites with a bus speed of up to 66 MHz ƒ Gigabit Ethernet interface plus an additional 10/100BaseTX Ethernet interface ƒ 64-bit PCI expansion mezzanine connector allowing up to four more PMCs ƒ I/O compatibility with MVME51xx family ƒ Support for processor PMCs (PrPMCs) MVME5500 NXP® MPC7457 VME SBC The MVME5500 from SMART Embedded Computing uses the MPC7457 processor running at 1 GHz, balanced with memory, dual independent local buses and I/O subsystems. The powerful Marvell 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 including those in defense and aerospace, industrial automation and transportation. 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.

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 dual independent 33/66 MHz PMC sites. MVME5500 Block Diagram MVME5500 Data Sheet TRANSITION MODULES 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, DCE or DTE via the installation of SMART EC Serial Interface Modules (SIMs). A P2 adapter board provides interface signals to the MVME761 transition module. Two separate P2 adapter boards are available: one for 3-row backplanes and one for 5-row backplanes. The 3-row P2 adapter board provides connection for 8-bit SCSI. A 5-row P2 adapter board supports 16-bit SCSI and PMC I/O. Software Support FIRMWARE MONITOR Firmware must fulfill the traditional functions of power-on self-test (POST), initialization, low-level setup and debug, and operating system booting. SMART EC’s innovative firmware (known as MOTLoad) that is resident on the MVME5500 exceeds these requirements with expanded features such as interrupt driven I/O, more comprehensive power-up tests and extensive diagnostics with new scripting capability. And of course, MOTLoad provides a debugger interface similar to the time proven “bug” interface on previous VMEbus boards from SMART EC.
