VMIC VMIVME-7589A Single Board Computer

Module Feature

VMIVME-7589A is a single-slot 6U VMEbus single board computer (SBC) developed by VMIC(GE Fanuc),based on Pentium-class processor,designed as the main controller for standard VME / VME64 chassis. It can act as VME system master to access all I/O modules installed on backplane. Onboard memory supports up to 512 MB DDR RAM,equipped with compact flash / IDE storage interface for system boot and local data storage. Front panel integrated rich I/O: dual 10/100 Mbit Ethernet ports,SVGA video output,dual RS232/422 serial ports,USB port and PS/2 keyboard & mouse connector. VME bus supports A16/A24/A32 addressing and D08/D16/D32,BLT block transfer. Battery-backed SRAM retains critical system parameters after power loss. Built-in BIT diagnostic monitors CPU,memory,power rail and peripheral interfaces,status registers available for system software reading. Rugged Eurocard PCB with conformal coating,shock and vibration screened for power plant cabinet environment,widely used in gas/steam turbine VME control host,aerospace ground test bench,hardware-in-loop real-time simulation and industrial distributed data acquisition chassis.

Working principle

Pentium CPU runs real-time OS and user application program. As VME bus master,it issues bus commands to read/write all VME slave I/O boards. Onboard north/south bridge handles memory,storage and peripheral communication. Front panel I/O controller manages network,display and serial port data transmission. BIT circuit executes memory test,register check and peripheral loopback test during boot-up. VME FPGA performs VME bus arbitration,address decoding and block data transfer. Backup SRAM keeps configuration data safe during power outage.
