MD80862

Overview

The MD80862 is an integrated circuit microprocessor belonging to the iAPX86 family, originally manufactured by Intel and later supported under the Altera brand portfolio. It functions as a single-core, 16-bit processor with a maximum clock frequency of 8 MHz. The component is housed in a 40-lead Ceramic Dual In-Line Package (CDIP). This device serves as a foundational processing unit for legacy embedded systems requiring 16-bit architecture compatibility.

Feature Summary

• Implements the iAPX86 instruction set architecture for 16-bit processing operations
• Operates at a base clock speed of 8 MHz
• Utilizes a 40-pin CDIP package for robust physical integration

Applications

• Legacy industrial control systems
• Historical embedded computing platforms
• Retro-computing hardware restoration

Procurement Notes

Verify manufacturer origin carefully, as this part may be listed under both Intel and Altera designations due to corporate acquisition history. Confirm the specific suffix indicates the 8 MHz speed grade and CDIP package variant. Ensure authenticity through authorized mature device distributors, as original production has ceased. Cross-reference datasheets for pinout compatibility before integration into existing designs.

Selection Notes

Select this component only when strict compatibility with the iAPX86 16-bit architecture is required. Consider the 8 MHz performance limit against system timing constraints. Evaluate the 40-CDIP package requirements for PCB layout and socket availability. Assess long-term supply chain stability given the mature status of the device.

Part Context

This microprocessor represents a transition period in semiconductor branding following Intel's acquisition of Altera. While functionally identical to Intel's original iAPX86 designs, it appears in catalogs associated with Altera's broader component offerings. It is distinct from Altera's FPGA products, serving instead as a discrete CPU solution for specific embedded applications.

Replacement Considerations

Direct replacements are limited due to the proprietary nature of the iAPX86 architecture. Verify pin-to-pin compatibility with other 8086 variants if available. Software migration strategies should be considered if substituting with modern 16-bit processors.
