Emerson MVME6100 series VMEbus single board computer

Emerson MVME6100 series VMEbus single board computer

Product positioning and core values

The MVME6100 series is the first VMEbus single board computer (SBC) launched by Emerson Network Power, which uses the Tundra Tsi148 VMEbus interface chip and focuses on "business critical continuity embedded computing". Its core advantage lies in achieving a bus transmission rate of 320MB/s through the 2eSST VMEbus protocol, while balancing the performance of the processor, memory, local bus, and I/O subsystem. It can meet the high reliability and high bandwidth embedded computing needs of defense aerospace, industrial automation, medical imaging, and other fields, and is compatible with existing VMEbus infrastructure to protect users' existing investments.

Compatibility: Equipped with Texas Instruments' new VMEbus transceiver, it can be connected to standard VMEbus backboards and is compatible with existing VMEbus boards, backboards, chassis, and software

PCI and Expansion Interface

2 33/66/100 MHz PMC-X slots: support industry standard PMC/PrPMC modules, expandable for application specific functions (such as multiprocessors)

32/64 bit 33/66 MHz PCI expansion interface: supports PCI expansion carriers such as Emerson PMCSpan

64 bit/133 MHz PCI-X bus: connects Tsi148 VMEbus interface chip with PMC-X slot to ensure high bandwidth transmission

network interface

Dual Gigabit Ethernet interface, controller integrated into host bridge, speed 10/100/1000Mbps

Connection method: 1 router to front panel RJ-45, 1 can be routed to front panel RJ-45 or P2 interface (10/100Mbps router to MVME761 RJ-45 in IPMC mode, gigabit router to P2 in PMC mode)

serial interface

Asynchronous serial ports: 2 16550 compatible ports, EIA-574 DTE configuration, maximum baud rate of 38.4Kbps (EIA-232)/115Kbps (raw rate), 1 routed to front panel RJ-45, 1 used for development

Extended serial port (requires IPMC module): IPMC761 provides 2 asynchronous+2 synchronous ports, IPMC712 provides 3 asynchronous+1 synchronous port, supports EIA-232/DCE/LTE configuration

Other interfaces

Parallel port: Supports IEEE 1284 standard (MVME761 for HD-36 interface, MVME712M for D-36 interface, Centronics compatible)

SCSI interface: The IPMC module is equipped with Symbios 53C895A controller, supporting 8-bit (5.0MB/s asynchronous) and 16 bit (20.0MB/s Ultra SCSI), and needs to be connected through a P2 adapter

Software support
