Product Overview: MOTOROLA MVME2101-1 Single Board Computer
The MOTOROLA MVME2101-1 is a high-performance Single Board Computer (SBC) designed for embedded applications requiring robust computing power, extensive I/O capabilities, and reliable operation in demanding environments. Part of Motorola’s renowned MVME2100 series, this board leverages the advanced PowerPC architecture to deliver superior processing performance for industrial automation, telecommunications, military, and aerospace systems. The “-1” suffix denotes a specific factory configuration, typically indicating particular memory, processor speed, or feature set variations.
Engineered for the VMEbus (Versa Module Eurocard) architecture, the MVME2101-1 serves as a critical component in systems where real-time processing, expandability, and longevity are essential.
Key Features & Benefits
High-Performance PowerPC Processor:
- Features a Motorola MPC750 or MPC755 RISC processor, offering advanced superscalar architecture, high clock speeds (e.g., 400 MHz to 1 GHz+), and integrated L1/L2 cache. This provides significant computational power for complex real-time applications.
VME64 Bus Interface:
- Fully compliant with the VME64 standard, supporting 32/64-bit data transfers and system controller functionality. Ensures seamless integration into existing VME systems and high-bandwidth communication with other VME boards.
Advanced Memory Architecture:
- Equipped with SDRAM (typically 128 MB to 512 MB, depending on configuration) for high-speed data processing.
- Includes Flash memory for boot code and firmware storage, enhancing reliability by eliminating mechanical storage devices.
Dual PCI Mezzanine Card (PMC) Sites:
- Supports two PMC expansion slots, enabling flexible customization with additional I/O interfaces such as Ethernet, Fiber Channel, SCSI, or custom digital/analog I/O. This modularity allows the board to adapt to diverse application requirements.
Integrated Connectivity:
- Dual 10/100 Ethernet ports for network communication.
- Serial ports (RS-232/422/485) for legacy device connectivity.
- USB ports for peripheral integration.
Ruggedized Design:
- Built to operate in harsh conditions with extended temperature tolerance, resistance to shock and vibration, and industrial-grade component reliability.
