AM9516A-1PC

Overview

The AM9516A-1PC 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 accommodates eight external interrupt inputs and is housed in a 28-pin DIP package with a ceramic, glass-sealed body. It functions within a temperature range of -40 °C to +85 °C. The component features a rectangular inline form factor with a maximum seated height of 5.715 mm and a length of 37.1475 mm.

Feature Summary

• Provides universal interrupt control capabilities for embedded systems
• Interfaces with 8-bit external data buses
• Supports multiple external interrupt sources

Applications

• Embedded processor interrupt management
• Microcontroller system integration
• Industrial control unit signal handling

Procurement Notes

Verify the specific suffix '1PC' against official AMD documentation to confirm package type and temperature grade. Ensure compatibility with existing 5 V logic levels and 8-bit bus architectures. Confirm RoHS status as historical AMD components may not meet current environmental standards. Validate pinout alignment with target PCB footprint before procurement.

Selection Notes

Select this component when an 8-bit architecture requires dedicated hardware interrupt handling. The ceramic DIP package suits high-reliability or legacy industrial environments. Consider thermal constraints given the specified operating range. Verify that the 5 V supply voltage aligns with the system's power distribution network.

Part Context

This part belongs to the AMD AM9516 family of interrupt controllers. These devices were designed for early microprocessor systems requiring efficient interrupt vectoring. The AM9516A variant offers enhanced performance over earlier models. The PC suffix typically denotes a plastic or ceramic DIP package variant depending on the specific manufacturing batch documentation.

Replacement Considerations

Direct replacements are limited due to the age of the component. Check for AMD AM9516A variants with compatible suffixes. Generic interrupt controllers may require significant circuit redesign. Consult AMD archives for exact pin-compatible substitutes.
