Description
Motorola MVME2308
Technical Specifications
- Microprocessor: 300 MHz MPC604 PowerPC processor.
- Cache: 32KB instruction cache and 32KB data cache.
- Memory: Supports 16MB to 128MB of ECC-protected DRAM.
- Flash Memory: Up to 5MB of Flash storage.
- Bus Interface: Full 6U VMEbus system controller and slave interface.
Functional Features
- High-Bandwidth Architecture: Optimized PCI local bus and memory controller delivering exceptional data throughput.
- PMC Expansion: Dual IEEE P1386.1 PMC slots supporting single or double-width PCI mezzanine cards.
- Communication: Integrated 10/100Base-T Ethernet interface and multiple serial ports.
- Data Integrity: Utilizes the Falcon chipset for dual-interleaved memory access with single-bit error correction and double-bit error detection.
Application Scenarios
Widely deployed in aerospace, defense electronics, industrial automation, semiconductor manufacturing, and mission-critical test and measurement systems.
Performance Parameters
- Operating Temperature: 0°C to 55°C inlet air with forced-air cooling.
- Storage Temperature: -40°C to +85°C.
- Power Requirements: High power draw requiring ample +5V current from the chassis backplane.
Material Composition
Constructed with multi-layer industrial-grade PCBs. Critical integrated circuits are covered with a protective conformal coating to withstand moisture, dust, and corrosive gases.
Structural Characteristics
Standard 6U VME European card form factor occupying a single slot. The front panel provides reset/abort switches, status LEDs, and external I/O interfaces.
Working Principle
The MPC604 processor connects to the local PCI bus via the Raven PCI bridge ASIC and to the ISA bus via the W83C553 bridge. The Universe ASIC routes data between the PCI local bus and the VMEbus. The processor fetches external data, performs real-time computations using high-bandwidth memory, and outputs results via Ethernet or serial ports.
Installation Requirements
- Must be installed in a VME64 standard chassis backplane.
- Requires robust forced-air cooling (minimum 100 CFM axial fan) due to higher power dissipation.
- Insert into the backplane by aligning with the guide rails and applying even pressure to prevent pin bending.
Usage Precautions
- Strictly adhere to Electrostatic Discharge (ESD) protection protocols.
- Ensure system power is completely disconnected before insertion or removal.
- Periodically check the NVRAM backup battery to prevent configuration data loss.
