Description
Motorola MVME2700-1241A
Technical Specifications
- Processor: 233 MHz MPC750 PowerPC.
- Memory: 16 MB – 256 MB ECC DRAM (RAM200).
- Cache: 32 KB L1 I/D, 1 MB L2 backside.
- Storage: 8 MB Flash + 1 MB socketed Flash.
Functional Features
- Multi-Processor Support: Hardware support for inter-CPU interrupts and status queries.
- GCSR: Global Control Status Register for broadcast signaling.
- Flexible I/O Mapping: Programmable mapping decoder via Raven bridge.
- Timers: Four 32-bit timers + M48T559 watchdog.
Application Scenarios
Telecom switching, medical equipment, CNC machines, aerospace test platforms, industrial automation.
Performance Parameters
- VME Transfers: A24/A32, D8/D16/D32/D64 block mode.
- Interrupts: Managed via Raven and Winbond PCI-ISA controllers.
- Network: 10/100Base-TX with DMA.
Material Composition
FR4 industrial PCB with solid capacitors, high-frequency decoupling, and gold-plated connector pins.
Structural Characteristics
Eurocard VME size. Front panel: 6 LEDs (CHS, BFL, CPU, FUS, SYS, PCI) + 7-segment debug display.
Working Principle
CPU accesses ECC memory via high-speed bus. PCI DMA handles fast memory-VME transfers. Firmware monitor supports debugging and OS boot.
Installation Requirements
Ensure chassis grounding. Use transition modules for external serial/SCSI connections.
Usage Precautions
Avoid unshielded operation in high EMI. Check FUS LED for polyswitch status. Do not modify hardware jumpers.
