The MVME5500 is a single-board computer based on the PowerPC MPC7455 processor and the Marvell GT-64260B host bridge with a dual PCI interface and memory controller. On-board payload includes two PMC slots, two SDRAM banks, an expansion connector for two additional banks of SDRAM, 8MB boot Flash ROM, one 10/100/1000 Ethernet port, one 10/100 Ethernet port, 32MB expansion Flash ROM, two serial ports, NVRAM and a real-time clock.
The MVME5500 interfaces to a VMEbus system via its P1 and P2 connectors and contains two IEEE 1386.1 PCI mezzanine card (PMC) slots. The PMC slots are 64-bit and support both front and rear I/O. Additionally, the MVME5500 is user-configurable by setting on-board jumpers. Two I/O modes are possible: PMC mode or SBC mode (also called 761 or IPMC mode). The SBC mode uses the IPMC712 I/O PMC and the MVME712M transition module, or the IPMC761 I/O PMC and the MVME761 transition module. The SBC mode is backwards compatible with the MVME761 transition module and the P2 adapter card (excluding PMC I/O routing) used on the MVME5100 product. This mode is accomplished by configuring the on-board jumpers and by attaching an IPMC761 PMC in PMC slot 1. Secondary Ethernet is configured to the rear.
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.
