​Product Overview: Motorola PMCSPAN-002 I/O Expansion Module​

The ​​Motorola PMCSPAN-002​​ is an ​​I/O expansion module​​ designed for use with Motorola’s VMEbus-based single-board computers (SBCs) and embedded systems. This module provides additional input/output capabilities through a ​​PCI Mezzanine Card (PMC)​​ interface, enabling flexible integration of custom or specialized I/O functions into Motorola’s computing platforms. Typically used in industrial automation, telecommunications, and military applications, the PMCSPAN-002 enhances system scalability and adaptability by allowing users to add tailored I/O solutions without modifying the core computing hardware.

​Key Features & Benefits​

​PMC Interface Compatibility​​:
Utilizes the standardized ​​IEEE 1386 PCI Mezzanine Card (PMC)​​ interface, ensuring compatibility with a wide range of PMC modules for serial communication, digital I/O, analog I/O, or specialized networking functions.

​Seamless Integration with Motorola SBCs​​:
Designed to work with Motorola’s VMEbus SBCs (e.g., MVME1600/2600/3600 series), providing a streamlined path for expanding I/O capabilities in embedded systems.

​High-Speed Data Transfer​​:
Supports PCI bus speeds for efficient data exchange between the PMC module and the host SBC, minimizing latency in critical applications.

​Ruggedized Design​​:
Built to withstand harsh industrial environments, with components rated for extended temperature ranges and resistance to vibration/shock.

​Flexible Configuration​​:
Allows customization through user-selectable PMC modules, enabling support for protocols such as ​​Serial RS-232/422/485​​, ​​Ethernet​​, ​​CAN bus​​, or ​​digital/analog I/O​​.

​Hot-Swap Support (Optional)​​:
Some configurations may support hot-swappable PMC modules, reducing downtime during maintenance or upgrades.
