AM9516A-8PC

Overview

The AM9516A-8PC is a Universal Interrupt Controller manufactured by Advanced Micro Devices. It operates on a single 5 V power supply and supports an 8-bit external data bus width. The device provides eight external interrupt inputs for system management. It is housed in a 28-pin DIP package with a ceramic, glass-sealed body. The component functions within a temperature range of -40 °C to +85 °C.

Feature Summary

• Supports eight distinct external interrupt sources for centralized control
• Integrates an 8-bit parallel interface for microprocessor communication
• Utilizes a robust ceramic package suitable for demanding environments

Applications

• Microprocessor-based systems requiring interrupt management
• Industrial control units operating in wide temperature ranges
• Legacy computing hardware utilizing 8-bit architectures

Procurement Notes

Verify the specific suffix '8PC' against official AMD documentation to confirm pinout and speed grade compatibility. Ensure the procurement source provides valid traceability for the ceramic DIP package. Confirm RoHS status as historical records indicate non-compliance for this era of manufacturing. Validate that the supplier guarantees authenticity for vintage semiconductor components.

Selection Notes

Select this component when designing systems requiring an 8-bit parallel interface and support for eight interrupt lines. The ceramic DIP package offers durability for industrial applications. Verify that the target system operates at 5 V logic levels. Consider the thermal specifications if the deployment environment exceeds standard commercial limits.

Part Context

This part belongs to the AMD 9516 series of universal interrupt controllers. These devices were designed to manage complex interrupt structures in early microprocessor systems. The AM9516A variant represents an enhanced version of the original controller, offering improved performance characteristics while maintaining backward compatibility with existing system architectures.
