1. Product Overview
MVME5100 is Motorola’s mid-tier PowerPlus II VME single board computer, designed as a cost-effective upgrade replacement for aging MC68040 MVME162 series without full platform rewrite. It supports two PowerPC families: low-power G3 MPC750/755 for general control tasks, and MPC7410 G4 with AltiVec SIMD coprocessor for heavy floating-point trend & algorithm computation.
Built with Hawk integrated ASIC as PCI-VME bridge, it separates CPU local bus, PCI peripheral bus and VME backplane traffic to guarantee hard real-time determinism. The board fits one standard 6U VME slot, carries two independent 32/64-bit PMC mezzanine slots for flexible I/O expansion, plus an auxiliary PCI connector to add up to four extra PMC modules.
All memory is ECC error-correcting SDRAM to resist EMI data corruption inside industrial cabinets. Dual 10/100 Fast Ethernet ports provide network redundancy for fault-tolerant DCS control networks. Dual-bank soldered Flash enables safe field firmware upgrades without bricking the board. The TM wide-temperature variant uses industrial-grade semiconductors, reinforced power filtering and conformal coating for -40℃ cold-start operation in unmanned outdoor, mining and offshore racks.
Widely deployed for legacy Honeywell TDC3000 system hardware refresh, acting as mid-performance LCN operator station and process monitoring node, stepping up to MVME5500 Gigabit platform for higher throughput demand.
