Product Details:

MOTOROLA MVME162-211 belongs to MVME162LX 6U VMEbus single board computer lineup, equipped with MC68LC040 25MHz 32-bit processor, integrated MMU and 8KB cache, without hardware FPU. This variant is fitted with 4MB parity DRAM, 128KB battery-backed SRAM, four EIA-232-D serial ports, onboard 10Mbps Ethernet transceiver and dual IndustryPack expansion slots, and it does not carry SCSI controller. It integrates 1MB flash memory for firmware storage, battery-backed real-time clock, multi-channel timers and hardware watchdog. The built-in MVME162Bug monitor supports serial console debugging, memory verification and boot parameter setup. This legacy board has been discontinued, available units are refurbished spares for vintage VME automation systems.

This SBC can operate as VMEbus master or slave, supporting A16/A24/A32 addressing and D8/D16/D32 data transfer with interrupt management. It combines multi-channel serial interfaces and Ethernet networking, allowing connection to multiple serial field instruments and host network at the same time. Users can install IndustryPack mezzanine modules to add analog or digital signal channels according to project needs. Optimized PCB routing mitigates electrical noise from servo drives and harsh factory environments. It maintains stable operation with VxWorks and other classic real-time operating systems.

It adopts standard 6U eurocard form factor and draws +5V, ±12V power 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 is not supported; power must be cut before board installation or removal. The board assembly meets industrial shock and vibration specifications for cabinet mounting.

It is widely used in distributed monitoring systems and factory test stations requiring both serial links and network upload. Typical application scenarios include VME rack auxiliary CPU replacement, multi-drop serial network upgrade and old automation equipment maintenance. Automation integrators select this Motorola MVME162-211 for its MC68LC040, 25MHz 4MB parity DRAM configuration, four EIA-232-D serial ports, Ethernet and dual IndustryPack slots, no SCSI.
