Product Details:

MOTOROLA MVME162-523 belongs to MVME162FX 500 series 6U VMEbus single board computer, equipped with MC68040 32MHz 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, one Centronics parallel port, onboard narrow SCSI controller and 10Mbps Ethernet transceiver, paired with four IndustryPack expansion slots. 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, SCSI boot 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 integrates parallel printer interface, configurable serial channels, DMA SCSI mass storage and Ethernet data transmission on one single board. Users can install up to four IndustryPack mezzanine modules to expand analog, digital and special signal interfaces to build multi-channel complex control and 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, parallel port and status LED indicators, and the P2 rear connector routes Ethernet, SCSI 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 legacy motion control racks and semiconductor test subsystems requiring full set of I/O, SCSI storage and Ethernet communication. Typical application scenarios include VME rack main CPU replacement, multi-function data logging system maintenance and complex automation platform retrofit. Automation integrators select this Motorola MVME162-523 for its MC68040 FPU, 32MHz 8MB parity DRAM configuration, configurable serial ports, Centronics port, SCSI, Ethernet and four IndustryPack slots.
