CS82C37A overview
CS82C37A is a component documented by Harris Corporation. The PDF description identifies it as "CMOS High Performance Programmable DMA Controller." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- A 0.1µF capacitor between pins 31 and 20 is recommended for decoupling.
- This input may be driven from DC to 12.5MHz for the 82C37A-12, from DC to 8MHz for the 82C37A, or from DC to 5MHz for the 82C37A-5.
- In 8080A, 8085A, 80C88, or 80C86 systems, this will ensure one full machine cycle execution between DMA transfers.

Engineering review checklist
- Confirm supply rails, clock limits, memory size, peripheral mapping and I/O voltage compatibility.
- Check package pinout, boot configuration, programming interface and silicon-revision errata.
- Budget decoupling, thermal margin, startup timing and firmware recovery behavior before release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
