Description

The Emerson Network Power MVME5500 series is designed to meet the needs of OEMs including those in 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. The MVME5500 utilizes the MPC7457 processor running at 1 GHz, which is ideal for data intensive applications. The MVME5500 provides more than just better processor performance; it also provides balanced performance from the processor, 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。
