Description
Motorola MVME2434-3
Technical Specifications
- Microprocessor: PowerPC 750 32-bit RISC microprocessor.
- Clock Speed: Operates at 350 MHz.
- Cache: 32 KB L1 instruction cache, 32 KB L1 data cache, and 1 MB back-end secondary cache.
- Memory: 128 MB of board-mounted ECC SDRAM (Error-Correcting Code).
- Flash Memory: Up to 4 MB for firmware storage.
Functional Features
- High Bandwidth: Delivers exceptional memory read/write bandwidth and PCI throughput without starving the processor.
- Expansion: Features two IEEE P1386.1 compatible PMC expansion slots and a 64-bit PCI expansion mezzanine connector.
- Communication: Equipped with dual 10/100Base-TX Ethernet ports and dual 16550-compatible asynchronous serial ports.
- System Management: Integrated Multi-Processor Interrupt Controller (MPIC), watchdog timers, and 32 KB NVRAM with battery backup.
Application Scenarios
Widely deployed in industrial automation, advanced data acquisition, telecommunications infrastructure, aerospace, and defense electronics.
Performance Parameters
- Operating Temperature: -40°C to +85°C (with conformal coating for condensing humidity environments).
- Altitude: Capable of operating at altitudes up to 50,000 feet.
- Vibration Standards: Meets MIL-STD-810G and DO-160D vibration standards.
Material Composition
Constructed with multi-layer industrial-grade PCBs. Critical integrated circuits are covered with a protective conformal coating to withstand extreme 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 PowerPC 750 processor connects to the local PCI bus via an optimized PCI bridge-memory controller ASIC. The Universe II bridge chip facilitates seamless VME-to-PCI transactions, ensuring efficient data transfer between on-board peripherals and the VME backplane.
Installation Requirements
- Must be installed in a VME64 standard chassis backplane.
- Requires robust forced-air cooling to maintain optimal operating temperatures in extreme environments.
- 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.
