Description
Motorola MVME2700-1231A
Technical Specifications
- CPU: 233 MHz MPC750 PowerPC.
- DRAM: 16 MB – 256 MB ECC.
- Flash Storage: 8 MB onboard, 1 MB socketed.
- Cache: 32KB/32KB L1, 1MB L2.
Functional Features
- Modular Memory: RAM200 mezzanine design for field upgrades.
- Rich I/O: Async/sync serial ports, parallel, floppy, keyboard/mouse.
- Network & Storage: Ethernet with PCI DMA, Fast SCSI-2.
- System Protection: 8KB NVRAM, RTC, watchdog timer.
Application Scenarios
Widely used in DCS, flight simulators, radar/sonar, and semiconductor manufacturing.
Performance Parameters
- Bus: 64-bit PCI mezzanine connector.
- Firmware: On-board debug monitor with POST.
- Expansion: IEEE P1386.1 PMC slot.
Material Composition
UL94V-0 flame-retardant PCB with high-reliability packaging and anti-vibration solder joints.
Structural Characteristics
6U VME size. Front panel includes status LEDs, ABORT, and RESET switches. P1/P2 VME connectors.
Working Principle
MPC750 manages PCI peripherals via Raven bridge and VME via Universe bridge. Firmware performs POST, then loads the OS.
Installation Requirements
Insert into VME chassis, align P1/P2, lock securely. Provide +5V, +12V, -12V DC power. 3.3V/2.5V derived internally.
Usage Precautions
Wear ESD strap. Never hot-swap. Ensure system has global bus timeout if used as non-system controller.
