MD8086-2

Overview

The Altera MD8086-2 is a microprocessor IC based on the Intel iAPX86 architecture. It features a single core with 16-bit data processing capabilities and operates at a clock frequency of 8MHz. The component is housed in a 40-pin Ceramic Dual In-Line Package (CDIP). It functions as a central processing unit for embedded systems requiring 16-bit computational power.

Feature Summary

• Implements the iAPX86 instruction set architecture
• Provides 16-bit internal and external data bus width
• Operates with a standard 5V supply voltage
• Supports up to 1 MB of physical memory addressing

Applications

• Legacy industrial control systems
• Embedded computing modules
• Historical PC-compatible hardware platforms

Procurement Notes

Verify manufacturer origin carefully, as Altera primarily produces FPGAs while this part originates from Intel's processor lineage. Confirm package integrity due to age. Ensure compatibility with existing system clocks and memory controllers before integration into modern designs.

Selection Notes

Select this component only when specific legacy compatibility with the 8086 instruction set is required. Consider that it is a discontinued part; verify availability through authorized distributors or surplus suppliers. Evaluate if modern FPGA implementations can replicate its functionality more reliably.

Part Context

This part belongs to the early generation of x86 microprocessors developed by Intel. Although listed under Altera in some marketplaces, the silicon design and specifications are derived from Intel's iAPX86 family. It represents a foundational 16-bit CPU technology used in early personal computers and embedded applications.
