Motorola RSG2PMC & RSG2PMCF-NK2 High-Density Processor & Communication Modules
Motorola RSG2PMC & RSG2PMCF-NK2 High-Density Processor & Communication Modules
The Motorola RSG2PMC and its variant, the RSG2PMCF-NK2.
are high-performance PCI Mezzanine Card (PMC) modules designed for embedded computing and telecommunications infrastructure.
These modules provide a powerful processing engine and flexible communication interfaces,
often utilized as daughtercards on VME, VXS, or CompactPCI carrier boards to expand system logic and I/O capabilities.

Product Advantages and Features
Mezzanine Flexibility: The PMC design allows these modules to be added to various baseboards, providing a cost-effective way to upgrade processing power without replacing the entire system.
NK2 Performance Optimization: The RSG2PMCF-NK2 variant features specific hardware revisions (NK2) for improved data throughput and stability in high-traffic network environments.
Deterministic Real-Time Response: Engineered for mission-critical applications where timing and low-latency interrupt handling are paramount.
Rugged Build Quality: Built to withstand the rigors of industrial racks, including thermal cycling and moderate mechanical vibration.
Application Cases
Telecommunications: Serving as the media gateway processor for high-density voice and data switching centers.
Defense & Aerospace: Integrated into flight simulation systems or shipboard command and control stations as processing nodes.
Industrial Automation: High-level supervisory control in complex DCS (Distributed Control Systems) environments.
Scientific Research: Data acquisition and pre-processing in particle physics or astronomical observation equipment.
Related & Other Models in the Series
RSG2PMC-V1: Standard base version for general-purpose logic.
RSG2-Series Carrier Boards: VMEbus or cPCI baseboards designed to host these PMC modules.
Motorola MCP750/MCP745: Complementary Single Board Computers (SBCs) often used in the same chassis.

Installation and Maintenance
Installation: Align the PMC module connectors with the mating connectors on the carrier board. Press firmly until the module is seated.
Secure the module using the four mounting screws from the underside of the carrier board to ensure a solid mechanical and thermal connection.
Electrostatic Discharge (ESD): Always use a grounded wrist strap. These modules contain highly sensitive CMOS components that can be damaged by invisible static charges.
Firmware Updates: Ensure the carrier board BIOS/Firmware is compatible with the RSG2PMCF-NK2 revision to ensure all I/O features are correctly mapped.
Cleaning: If used in open-frame environments, use dry compressed air to clear the mezzanine connectors of dust before installation.
Unique Product Description
The Motorola RSG2PMC and RSG2PMCF-NK2 represent the pinnacle of modular embedded design.
By decoupling the processor from the main system bus, Motorola created a solution that is both incredibly powerful and uniquely adaptable.
The NK2 designation specifically highlights a commitment to long-term industrial support, offering the refined stability required for systems that cannot afford a single second of downtime.
These modules are not just components; they are the “intelligence” that drives the world’s most critical infrastructure.
