8086-2/BQA

Overview

The AMD 8086-2/BQA is a 16-bit microprocessor based on the Intel 8086 architecture, manufactured by Advanced Micro Devices. It operates at a clock speed of 8MHz and features a single core with a 16-bit data bus width. The component is housed in a 40-pin Ceramic Dual In-line Package (CDIP). It supports an operating temperature range from -55°C to 125°C, indicating industrial-grade reliability. The device utilizes NMOS technology for its internal circuitry.

Feature Summary

• Implements the standard 8086 instruction set architecture for backward compatibility.
• Provides a 16-bit external data bus for efficient data transfer operations.
• Operates reliably within extended industrial temperature ranges.
• Utilizes ceramic packaging for enhanced durability and thermal stability.

Applications

• Industrial control systems requiring robust processing capabilities.
• Legacy computer system maintenance and restoration projects.
• Embedded applications utilizing established 8086-based architectures.
• Educational platforms demonstrating classic microprocessor functionality.

Procurement Notes

Verify the specific suffix BQA against official AMD documentation to confirm package type and temperature rating. Ensure the CDIP40 footprint matches your target PCB design. Confirm that the NMOS process technology aligns with your power and voltage requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate all electrical specifications directly from the manufacturer's datasheet before integration.

Selection Notes

Select this component when a verified 8086-compatible processor is required for legacy hardware support. Consider the 8MHz speed limit when evaluating system timing constraints. The ceramic package offers superior environmental resistance compared to plastic variants. Ensure the design accommodates the specific voltage levels associated with NMOS technology. Evaluate the physical size of the CDIP40 package against available board space.

Part Context

This microprocessor belongs to the early generation of x86 compatible chips produced by Advanced Micro Devices. It serves as a direct functional equivalent to the original Intel 8086, ensuring software compatibility. The 8086-2 variant typically denotes a faster clock speed version compared to earlier 5MHz models. AMD's production of this chip provided an alternative source for the foundational architecture of modern computing.

Replacement Considerations

Direct substitutes include other AMD 8086 variants such as the 8086-1 or 8086-2 in different packages. Verify pin compatibility for any cross-package replacements. Ensure the replacement maintains the same NMOS technology characteristics. Check if the substitute supports the required 8MHz frequency without modification.
