MOTOROLA MVME5500 NXP® MPC7457 VME SBC
The MVME5500 from Artesyn Embedded Technologies 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.
