MD8086

Overview

The MD8086-2 is a monolithic integrated circuit microprocessor belonging to the iAPX86 family, manufactured by Altera (Intel). It features a single core architecture with 16-bit data processing capabilities. The device operates at a maximum clock frequency of 8 MHz and is housed in a 40-pin Ceramic Dual In-line Package (CDIP). It supports standard 8086 processor instructions for swift processing tasks.

Feature Summary

• Integrates the core 8086 processor architecture for efficient instruction execution
• Provides 16-bit data bus width for internal processing operations
• Utilizes a robust ceramic dual in-line package for reliable mounting

Applications

• Legacy system integration requiring iAPX86 compatibility
• Embedded control applications utilizing 8MHz processing speeds
• Industrial equipment retrofits using CDIP form factors

Procurement Notes

Verify the specific suffix designation, such as -2, which indicates the operational speed grade of 8 MHz. Confirm that the package type matches the required 40-CDIP footprint. Ensure the component source aligns with Intel or authorized distributors, as this part originates from mature product lines. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when a legacy 8086 instruction set is mandatory for software compatibility. The 8 MHz speed rating suits applications where high-frequency performance is not critical but architectural fidelity is required. Consider the physical constraints of the 40-pin CDIP package against available PCB real estate. Evaluate thermal management needs associated with the ceramic packaging material.

Part Context

This microprocessor represents a bridge between traditional semiconductor manufacturing and programmable logic solutions offered by Altera. While primarily known for FPGAs, Altera distributed mature Intel processor components like the 8086 series. This specific unit serves niche markets requiring historical x86 compatibility within modern or specialized hardware environments.

Replacement Considerations

Direct substitutes include other variants within the iAPX86 family, such as the 8086-1 or 8086-2, differing primarily in clock speed ratings. Verify pin compatibility and voltage levels before swapping. Generic 8086 clones may lack the specific Altera/Intel quality assurance standards.
