Description
Motorola MVM2700-1221A
Technical Specifications
- Processor: PowerPC 750 (G3).
- Clock Speed: 233 MHz.
- Memory: 16 MB to 256 MB ECC DRAM.
- Flash: 8 MB onboard + 1 MB socketed.
Functional Features
- G3 Architecture: Superscalar execution for high instruction throughput.
- RAM200 Expansion: Supports modular memory upgrades without replacing the board.
- PCI Local Bus: High-speed interface for onboard Ethernet and SCSI.
- VME System Controller: Full arbitration and interrupt management.
Application Scenarios
Ideal for factory automation, robotics control, and telecommunications switching.
Performance Parameters
- L1 Cache: 32 KB Instruction / 32 KB Data.
- L2 Cache: 1 MB backside cache.
- Power: +5Vdc, 5A typical, 7A maximum.
Material Composition
High-reliability BGA components on multi-layer FR4 PCB with conformal coating options for harsh environments.
Structural Characteristics
Standard 6U VME form factor with front panel I/O connectors and diagnostic LEDs.
Working Principle
The PowerPC 750 boots from Flash, initializes the PCI bus and VME bridge, and loads the OS. Data is transferred via DMA between VME and local memory.
Installation Requirements
Ensure the VME backplane provides clean +5V, +12V, and -12V power. Align P1/P2 connectors precisely.
Usage Precautions
Static discharge can damage the G3 processor. Always ground yourself before handling. Do not operate without the air guide installed.
