Motorola MVME162-513A High-Performance VME Embedded Controller

Motorola MVME162-513A  High-Performance VME Embedded Controller

The Motorola MVME162-513A is a specialized, double-high VMEbus single-board computer designed for embedded monitoring and control.

Part of the legendary MVME162 family, the "513A" variant is a high-spec model featuring a 32 MHz processor,

integrated Ethernet, and SCSI interfaces. It serves as a robust engine for real-time applications, 

providing a balance of computational power and expansive I/O modularity via its IndustryPack® ports.

Technical Parameter Table

Product Advantages and Features

Full 68040 Performance: Unlike "LC" variants, the 513A includes the full MC68040 with an onboard FPU, making it suitable for complex mathematical calculations and signal processing.

Massive I/O Flexibility: With four IndustryPack slots, a single VME slot can be customized with various analog, digital, or specialized communication modules without increasing the system's physical footprint.

Integrated Connectivity: The built-in SCSI and Ethernet controllers reduce the need for additional peripheral cards, saving valuable backplane space.

Reliable Data Retention: Features battery-backed SRAM and NVRAM (8K x 8) alongside a Time-of-Day (TOD) clock to ensure system parameters are preserved during power loss.

Deterministic Real-Time Support: Optimized for use with RTOS environments like VxWorks, OS-9. and pSOS.

Application Cases

Industrial Automation: High-speed logic control in automotive assembly lines and semiconductor manufacturing.

Defense & Aerospace: Embedded processing in flight simulators and naval communication racks.

Scientific Research: Data acquisition nodes in high-energy physics labs (common in EPICS environments).

Legacy System Upgrades: A drop-in replacement for older 68020 or 68030 VME boards in mission-critical infrastructure.

Other Models in the Same Series

The MVME162 series is highly scalable based on MPU and memory needs:

MVME162-012/013: 25 MHz MC68LC040 (No FPU) variants.

MVME162-533: 32 MHz MC68040 with 16 MB DRAM for memory-intensive tasks.

MVME162FX Series: Enhanced versions with faster clock speeds (up to 200 MHz on later models).

MVME712M: Transition module used to bring internal I/O to industry-standard front-panel connectors.

Installation and Maintenance

Installation: Align the board with the VMEbus P1 and P2 connectors. Use the injector/ejector handles to seat the board firmly. Ensure the cooling fans provide at least 10 CFM of airflow across the board.

Jumper Configuration: Before power-up, verify jumper settings for VMEbus system controller functions and SRAM battery enable (usually J1/J2 headers).

Battery Maintenance: The lithium batteries for SRAM and the TOD clock have a typical lifespan of 5-10 years. 

For "New Old Stock" units, these should be tested and replaced if the voltage drops below 2.8V.

Electrostatic Discharge (ESD): Always handle the board in an ESD-safe environment. The MC68040 and IndustryPack chips are highly sensitive to static.

Unique Product Description

The Motorola MVME162-513A is a "Swiss Army Knife" for the VMEbus. While other boards focus on a single task, the 513A combines a high-speed RISC-style processor with a modular mezzanine architecture.

This allows engineers to build a custom-tailored controller—mixing serial, analog, and digital I/O on a single board—while maintaining the rock-solid reliability of the Motorola 68K family.

It is the definitive choice for maintaining legacy performance without sacrificing modern expansion capabilities.
