Product Details:

MOTOROLA MVME162-521A belongs to MVME162FX 500 series 6U VMEbus single board computer, equipped with MC68040 33MHz 32-bit processor with integrated hardware FPU and 8KB on-chip cache and MMU. This variant is configured with 8MB parity DRAM, 512KB battery-backed SRAM, dual configurable EIA-232-D/EIA-530 serial ports, onboard 10Mbps Ethernet transceiver, paired with four IndustryPack expansion slots, it does not integrate SCSI controller. It integrates 2MB flash memory for firmware storage, battery-backed real-time clock, programmable tick timers and hardware watchdog circuit. The built-in MVME162Bug monitor supports serial console debugging, memory verification and network boot configuration. This legacy embedded board is end-of-life, available stock are refurbished replacement spares for vintage VME automation racks.

This SBC can act as VMEbus master or slave and supports A16/A24/A32 addressing and D8/D16/D32 data transfer with interrupt management. It is equipped with 8MB parity memory buffer, four IndustryPack expansion slots and Ethernet communication interface, supporting real-time data upload to upper host systems. Users can install different mezzanine modules to expand analog, digital and special signal interfaces to build multi-sensor distributed acquisition systems. Optimized multi-layer PCB routing suppresses electromagnetic noise interference from servo drives and heavy industrial cabinet environments. It maintains stable compatibility with VxWorks and other classic real-time operating systems.

It adopts standard 6U eurocard mechanical specification and draws +5V, ±12V power supply from the VME backplane. Front panel provides serial connectors and status LED indicators, and the P2 rear connector routes Ethernet and mezzanine signals to transition boards. Hot swap operation is not supported; power supply must be shut down before installation or removal. The PCB and soldering assembly meet industrial shock and vibration specifications for cabinet mounting.

It is widely deployed in distributed multi-channel data acquisition racks and laboratory test subsystems requiring floating-point operation, serial communication and Ethernet transmission, without local SCSI storage demands. Typical application scenarios include VME rack main CPU replacement, networked multi-instrument monitoring system maintenance and automation platform retrofit. Automation integrators select this Motorola MVME162-521A for its MC68040 FPU, 33MHz 8MB parity DRAM configuration, configurable serial ports, Ethernet and four IndustryPack slots, no SCSI.
