Description
Motorola MVME2700-3231A
Technical Specifications
- Processor: PowerPC 750™ 32-bit architecture.
- Memory Capacity: 16MB to 256MB ECC DRAM (via RAM200).
- Storage: 8MB on-board flash, 1MB slot flash.
- Cache: 32KB/32KB L1, 1MB L2 backside.
Functional Features
- Backplane Independence: DRAM expansion mezzanine allows memory upgrades up to 256MB without requiring extra VME slots.
- Robust Connectivity: Supports 2 or 3 asynchronous serial ports and 1 or 2 synchronous/asynchronous serial ports.
- Data Retention: Features 8KB x 8 NVRAM and a timer clock with a replaceable backup battery.
- Debug Support: Onboard debug monitor with extensive self-test diagnostics.
Application Scenarios
Ideal for complex distributed control systems (DCS), flight simulation, and advanced medical imaging systems.
Performance Parameters
- Bus Architecture: 64-bit PCI Mezzanine Connector.
- Storage Speed: Fast SCSI-2 bus interface supporting 8-bit or 16-bit configurations.
- Network: Ethernet transceiver interface with 32-bit PCI local bus DMA.
Material Composition
Manufactured using UL94V-0 flame-retardant industrial PCB materials with gold-plated VME connector pins for enhanced signal integrity.
Structural Characteristics
Standard single-board computer layout with a front panel providing physical switches, status LEDs, and standard I/O ports.
Working Principle
Upon power-up, the firmware executes hardware initialization and POST, subsequently loading the operating system into the ECC DRAM for real-time processing.
Installation Requirements
Ensure the VME chassis provides stable +5V, +12V, and -12V power rails. Secure the board using standard VME ejector handles.
Usage Precautions
Regularly check the NVRAM battery voltage to prevent configuration data loss. Avoid operating in environments with excessive conductive dust.
