Description
Motorola MVME2700-4321
Technical Specifications
- Processor: PowerPC 750 32-bit microprocessor.
- Memory: 16MB ECC DRAM.
- Cache: 32KB L1 plus 1MB L2 cache.
- Flash: 8MB onboard plus 1MB socketed.
- Interfaces: VMEbus P1/P2, PMC expansion, Ethernet, SCSI-2.
Functional Features
- Scanbe Panel Design: Features Scanbe-standard extractors and locking mechanisms for easy insertion and removal in specific industrial chassis.
- Base Control Capability: 16MB of memory is sufficient for most conventional logic control and I/O scanning tasks.
- Comprehensive Self-Diagnostics: Automatically performs thorough testing of the CPU, memory, PCI bus, and VME interface upon power-up.
- Flexible Serial Configuration: Supports flexible configuration of asynchronous and synchronous ports via Serial Interface Modules (SIM).
Application Scenarios
- Legacy System Upgrades: Replaces older M68K architecture VME processors for a smooth transition to the PowerPC platform.
- Remote I/O Control: Acts as a data aggregation and protocol conversion center for distributed I/O nodes.
- Building Automation: Manages HVAC and energy management systems in large commercial buildings.
Performance Parameters
- Operating Temperature: 0°C to 55°C (forced-air cooling required).
- Humidity: 5% to 90% (non-condensing).
- Bus Arbitration: Supports VMEbus arbitration and interrupt handling.
Material Composition
Industrial-grade PCB and electronic components; the Scanbe front panel is made of high-strength metal or engineering plastic to prevent damage during frequent insertions.
Structural Characteristics
- Dimensions: Double-high 6U VME with a base board depth of 6.3 inches.
- Panel Style: Scanbe-style handles providing comfortable grip and reliable mechanical locking.
- Connectors: Includes J1 through J14 internal and external connectors supporting LED mezzanines, debug interfaces, and PCI expansion.
Working Principle
Upon power-up, the PPCBug firmware initializes the 16MB ECC DRAM and checks hardware status. The operating system is then loaded, and the processor manages peripherals via the local bus while interacting with other modules in the chassis through the VME interface.
