    1. Product Overview
    MVME162-533A is the highest-spec single-height 6U VME single-board computer in the entire MVME162 product family, built for high-complexity industrial real-time control requiring large memory, native network/storage, and floating-point arithmetic. CPU core is MC68040 32MHz with integrated MMU + FPU, delivering high-precision floating-point calculation for DCS historical trend, complex interlock and process control algorithms. Fixed maximum memory configuration: 16MB parity-protected shared DRAM (the largest DRAM capacity of all single-height MVME162 models). Standard equipped with 512KB high-speed battery-backed SRAM for non-volatile real-time data cache during power fluctuations. Full onboard peripheral suite: Intel 82596CA 10/100Mbps Ethernet, NCR53C710 narrow SCSI storage controller, dual configurable RS232/422 serial ports, 1MB firmware Flash, MK48T08 8KB battery-backed NVRAM + TOD real-time clock, four independent IndustryPack IP expansion slots with dedicated DMA channels per slot. Fully VMEbus Rev 1.4 compliant, full A16/A24/A32 master/slave, D08/D16/D32/D64 BLT/SCT block DMA burst transfer, onboard VME system controller. Widely deployed as primary heavy-duty HM/Global Station host for legacy Honeywell TDC3000 DCS LCN network, replacing mid-range models like MVME162-522A for large-scale data logging and complex control logic. A suffix denotes revised hardware layout, reinforced industrial passive components, conformal coating option, standard operating temperature 0℃ ~ +70℃ forced air cooling.

    3. MVME162 High-End Single Height Model Comparison
    1. MVME162-512A: 32MHz FPU, 4MB DRAM, Ethernet+SCSI+512KB SRAM, mid-high spec
    2. MVME162-522A: 32MHz FPU, 8MB DRAM, Ethernet+SCSI+512KB SRAM, high spec
    3. MVME162-533A: 32MHz FPU, 16MB DRAM, Ethernet+SCSI+512KB SRAM, TOP flagship single-height
    Core Differentiator: MVME162-533A carries 16MB DRAM (double MVME162-522A, quadruple MVME162-512A) for massive process data caching; retains 4 IndustryPack I/O expansion slots absent on dual-height MVME162-220
    4. Key Core Features
