AM9517A-5JC

Overview

The AM9517A-5JC is a DMA controller manufactured by Advanced Micro Devices, utilizing MOS technology. It is housed in a ceramic dual in-line package (CDIP) with 40 pins and a 2.54 mm pin pitch. The device operates on a 5 V supply voltage within a commercial temperature range of -55 °C to +125 °C. It supports data transfer rates up to 5 MHz and features independent channel control for eight channels. The component includes hardware handshaking capabilities and programmable word counts.

Feature Summary

• Eight independent DMA channels with individual control logic
• Hardware handshaking support for reliable data transfer
• Programmable terminal count registers for flexible transfer lengths
• Ceramic dual in-line packaging for high reliability applications

Applications

• Industrial automation systems requiring robust data movement
• Military and aerospace electronic equipment
• High-reliability computing architectures

Procurement Notes

Verify the specific suffix JC against official AMD documentation to confirm the extended temperature range and ceramic package variant. Ensure compliance with RoHS directives if lead-free sourcing is required, as historical military-grade parts may contain lead. Confirm current manufacturing status and availability through authorized distributors or surplus suppliers.

Selection Notes

Select this component when high reliability and wide temperature operation are critical. Compare performance metrics such as transfer rate and channel independence against modern alternatives. Verify interface compatibility with existing system buses and ensure power supply requirements match the 5 V specification.

Part Context

The AM9517A series belongs to AMD's legacy peripheral component lineup, designed for complex data handling tasks before the prevalence of integrated memory controllers. This specific model represents a hardened version suitable for demanding environments, distinguishing it from standard commercial variants through its packaging and thermal specifications.

Replacement Considerations

Direct replacements are limited due to the specialized nature of legacy CDIP components. Evaluate modern DMA controllers with similar channel counts and interface protocols. Verify pinout compatibility and electrical characteristics to ensure seamless integration into existing designs.
