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.
