Description
The Motorola / Emerson MVME5500 (specifically identified by assembly code 01-W3885F-02C featuring the GT-64260B-B1-0 system controller) is a high-performance VMEbus Single-Board Computer (SBC) designed for data-intensive embedded applications, defense and aerospace systems, medical imaging, and heavy industrial automation.
Built around a robust PowerPC architecture, the MVME5500 provides long-term lifecycle support and backward compatibility for legacy VMEbus infrastructures while delivering high-speed processing and balanced I/O subsystems.

Core Features & Operating Capabilities
- High-Performance GT-64260B System Controller: The integrated Marvell Discovery GT-64260B chipset efficiently coordinates traffic between the 1 GHz PowerPC core, 133 MHz SDRAM memory banks, and dual independent 64-bit PCI local buses.
- Balanced Dual PCI Bus Architecture: Isolates the high-speed PMC expansion slots from the VMEbus Universe II interface, allowing PMC modules to run at full 66 MHz performance without slowing down backplane communications.
- Ruggedized Industrial Design: Engineered to operate reliably under extreme vibration, shock, and thermal conditions found in defense, aerospace, and high-availability industrial control enclosures.
- MOTLoad Firmware Environment: Features Motorola’s robust MOTLoad firmware supporting power-on self-tests (POST), extensive hardware diagnostics, script execution, and flexible operating system boot routines (VxWorks, Linux, real-time OS).
- Legacy VMEbus Backward Compatibility: Permits seamless upgrades for older systems running on MVME2300, MVME2400, or MVME5100 boards without requiring complete chassis or backplane re-engineering.
