MG82370-20/B

Overview

The MG82370-20/B is a 32-bit Direct Memory Access (DMA) controller manufactured by Altera. It functions as an embedded processor controller designed to manage data transfers between memory and peripherals without continuous CPU intervention. The component operates with a specified speed of 20 nanoseconds, indicating its clock cycle performance characteristics. It is packaged in a Bulk configuration, suitable for specific board assembly processes.

Feature Summary

• Provides dedicated hardware management for high-speed data movement operations
• Integrates as an embedded controller within processor architectures
• Supports 32-bit data bus width for efficient word-aligned transfers

Applications

• Embedded system data acquisition interfaces
• Peripheral-to-memory block transfer implementations
• Legacy Altera FPGA-based controller subsystems

Procurement Notes

Verify the exact package type and pinout compatibility with your target PCB layout before procurement. Confirm that the 20ns speed grade meets your system timing requirements. Ensure the supplier provides genuine Altera components to avoid counterfeit risks associated with mature devices. Check for any specific handling guidelines required for this component class during storage and assembly.

Selection Notes

Select this component when a dedicated hardware DMA engine is required for 32-bit data paths in Altera-based designs. Consider the 20ns operational speed against your system clock constraints. Evaluate if the embedded controller architecture fits your power and area budgets compared to soft-core alternatives. Verify availability status as this is a mature device from the Altera portfolio.

Part Context

This part belongs to the Altera Embedded Processors and Controllers family, specifically focusing on memory and DMA control functions. It represents legacy silicon from the pre-Intel acquisition era, often found in established industrial or telecommunications equipment. The component complements Altera's FPGA fabric by offloading data movement tasks, enhancing overall system throughput.

Replacement Considerations

Consult official Intel/Altera lifecycle documents for direct cross-references. Mature device substitutions may require verification of pin compatibility and electrical specifications. No public substitute part numbers are confirmed in the provided source material.
