    Motorola MVME162-210 Dual Height 6U VME Single Board Computer (MC68LC040 25MHz, 4MB DRAM, Ethernet + SCSI, No 512KB SRAM)
    Manufacturer: Motorola Embedded Systems (Later Emerson Embedded Computing)
    Model: MVME162-210
    Series: MVME162 Dual Height 6U VME SBC Family
    Type: Double-height 6U VME master CPU board, MC68LC040 25MHz (NO FPU), integrated Ethernet + SCSI, no battery-backed 512KB SRAM, max 4MB DRAM
    Function: Medium-load real-time embedded computing node for Honeywell TDC3000 auxiliary LCN stations, power plant, railway, offshore VME rack systems; dual configurable serial ports, no IndustryPack expansion slots, full A32/D64 D64 VME bus master, multi-stage hardware watchdog, battery-backed RTC/NVRAM; compatible with VxWorks, OS-9, pSOS+, LynxOS, OpenBSD/mvme68k RTOS
    1. Overview
    MVME162-210 is the entry dual-height variant of the MVME162 dual-height lineup, positioned below MVME162-220. It adopts double-height 6U VME mechanical layout (occupies two VME chassis slots), sacrificing all 4 IndustryPack IP expansion slots for larger PCB routing space. Core CPU is MC68LC040 25MHz with MMU, **no integrated FPU floating-point unit**, so it cannot execute high-precision floating-point process algorithms. Fixed memory configuration: 4MB parity-protected shared DRAM (cannot expand to 8MB unlike -220), no onboard 512KB battery SRAM (major difference vs -220/-13/-512A/-522A). Standard peripherals: 1MB firmware Flash, integrated Intel 82596CA 10/100Mbps Ethernet, NCR53C710 narrow SCSI storage controller, dual RS232/422 configurable serial ports, MK48T08 8KB NVRAM & TOD real-time clock, multi-level hardware watchdog timer, 8-channel front panel status LEDs and manual RESET/ABORT buttons. Typical deployment: medium-performance auxiliary background processing nodes for Honeywell TDC3000 LCN network, signal pre-processing and temporary data storage racks without heavy floating-point calculation requirements. Full A32/D64 D64 VME bus master & DMA burst transmission capability for high-speed cross-board data exchange.
    2. Full Technical Specifications

    3. Core Comparison: MVME162-210 vs MVME162-220 (Dual Height Series)
    1. CPU: -210 = MC68LC040 25MHz NO FPU; -220 = MC68040 25MHz with integrated FPU
    2. DRAM Max: -210 fixed 4MB only; -220 supports 1/4/8MB expandable parity DRAM
    3. Battery SRAM: -210 no 512KB SRAM; -220 standard equipped 512KB battery-backed SRAM
    4. Interfaces: Both carry full onboard Ethernet + narrow SCSI dual interfaces
    5. Expansion: Both dual-height models remove all 4 IndustryPack IP slots
    6. Positioning: -210 mid-load auxiliary node without floating-point demand; -220 heavy-load main station with full floating-point & large memory support
    4. Key Features
    • Dual-height 6U VME form factor with dedicated PCB space for stable network/SCSI signal routing
    • MC68LC040 low-power 25MHz CPU for integer-based medium-complexity industrial real-time tasks
