Description
Motorola MEM162-503
Technical Specifications
- Memory Capacity: High-capacity DRAM expansion.
- Architecture: Interleaved DRAM architecture.
- Error Detection: Parity protection with interrupt/bus exception support.
- Compatibility: Designed exclusively for the MVME162 platform.
Functional Features
- Optimized Performance: Interleaved design maximizes memory bandwidth for the MC680x0 processor family.
- Robust Error Handling: Detects parity errors and triggers appropriate system-level interrupts.
- Flexible Sizing: The DRAM map decoder accommodates different base addresses and sizes of mezzanine boards.
Application Scenarios
Ideal for high-speed data logging, network routing, and real-time control applications.
Performance Parameters
- Bandwidth: Interleaving significantly reduces memory access latency.
- Initialization: Requires standard DRAM initialization cycles before full operational status.
Material Composition
Premium industrial PCB materials with high-reliability memory chips and precision manufacturing.
Structural Characteristics
Low-profile mezzanine module with secure mechanical attachment points.
Working Principle
The module interfaces with the MCchip memory controller. The system software configures the base address and size, enabling the CPU to execute read/write operations across the interleaved memory banks efficiently.
Installation Requirements
Install in a static-free environment. Ensure all mounting screws are tightened to the specified torque.
Usage Precautions
Do not attempt to modify the module’s hardware configuration. Consult the MVME162 Programmer’s Reference Guide for detailed memory mapping instructions.
