5962-9054305MXA

Overview

The Harris Corporation 5962-9054305MXA is a CMOS High Performance Programmable DMA Controller, functionally equivalent to the industry-standard 82C37A. Fabricated using an advanced 2-micron CMOS process, it offers pin compatibility with NMOS designs while providing increased functionality and reduced power consumption. The device features four independent maskable channels with autoinitialization capability and supports cascading for expanded channel counts. It enables high-speed data transfers up to 4 MBytes/sec at an 8 MHz clock or 6.25 MBytes/sec at a 12.5 MHz clock. The fully static design allows for gated clock operation, minimizing power usage with an ICCSB of 10 µA maximum and ICCOP of 2 mA/MHz maximum.

Feature Summary

• Four independent maskable channels with autoinitialization capability
• High-speed data transfer rates supporting up to 6.25 MBytes/sec
• Fully static CMOS design permitting low power operation
• Compatible with internal register software reads

Applications

• Memory-to-memory data transfers
• System integration requiring NMOS 8237A pin compatibility
• Applications demanding low power consumption via gated clock operation

Procurement Notes

Verify the specific suffix 'MXA' against official Harris or Intersil documentation to confirm package type and temperature range. Ensure the component matches the required 82C37A functional specifications. Check for availability constraints as this may be a limited supply item. Confirm RoHS compliance status if required by your manufacturing standards. Validate that the supplier provides authentic Harris Corporation components.

Selection Notes

Select this component when an enhanced version of the 8237A DMA controller is needed with lower power consumption. It is suitable for systems requiring high-speed data transfers up to 6.25 MBytes/sec. Consider its TTL/CMOS compatibility for interface flexibility. Evaluate the need for four independent maskable channels and cascading capabilities. Ensure the application benefits from the static CMOS design's low power characteristics.

Part Context

This part belongs to the 82C37A series of programmable DMA controllers. It represents an evolution of the standard 8237A, offering improved performance through CMOS fabrication. The 5962 prefix indicates a military-grade or high-reliability variant often associated with Harris Corporation's specialized semiconductor offerings. It serves as a direct replacement for older NMOS-based DMA solutions in legacy systems.

Replacement Considerations

The 82C37A is the primary functional reference. Verify pin-for-pin compatibility with existing NMOS 8237A designs. Check if alternative CMOS versions from other manufacturers meet the same speed and power specifications. Ensure that any substitute supports the required 4 MBytes/sec or 6.25 MBytes/sec transfer rates.
