Description
Motorola MEM162-200-4
Technical Specifications
- Memory Capacity: 4 MB of DRAM.
- Memory Architecture: Interleaved architecture for enhanced performance.
- Form Factor: Mezzanine expansion module.
- Error Checking: Parity protection enabled.
Functional Features
- Interleaved Access: Utilizes an interleaved memory architecture to reduce wait states and improve data throughput.
- High Reliability: Parity protection ensures data integrity by detecting single-bit errors.
- System Integration: Expands the MVME162’s memory pool transparently to the operating system.
Application Scenarios
Deployed in data acquisition systems, radar signal processing, and complex distributed control systems (DCS) requiring rapid memory access.
Performance Parameters
- Throughput: Interleaved architecture provides faster sequential data access compared to non-interleaved modules.
- Compatibility: Fully compatible with the MCchip memory controller on the MVME162.
Material Composition
Industrial-grade PCB with high-density surface-mount technology (SMT) and robust DRAM modules.
Structural Characteristics
Compact mezzanine form factor designed for direct stacking onto the MVME162 baseboard.
Working Principle
The interleaved architecture divides memory into multiple banks, allowing the processor to access successive memory addresses in alternating banks, thereby overlapping read/write cycles and reducing latency.
Installation Requirements
Power off the chassis before installation. Align the module carefully with the baseboard connectors and secure with mounting hardware.
Usage Precautions
Do not mix this module with incompatible memory configurations. Verify parity settings in the system firmware to prevent boot failures.
