MD8088

Overview

The MD8088 is an 8-bit microprocessor IC belonging to the iAPX86 family, originally manufactured by Altera. It features a single core architecture with a maximum operating frequency of 5 MHz. The device is housed in a 40-pin Ceramic Dual In-line Package (CDIP). As a legacy component from the Intel/Altera ecosystem, it serves as a foundational processing unit for older embedded systems and industrial control applications requiring 8-bit processing capabilities.

Feature Summary

• Implements the iAPX86 instruction set architecture within a compact 8-bit design
• Provides a single-core processing environment optimized for low-frequency operation
• Utilizes a robust ceramic dual in-line package suitable for high-reliability environments

Applications

• Legacy industrial control systems
• Embedded data acquisition modules
• Retro computing hardware restoration

Procurement Notes

Verify authenticity carefully as this is a mature legacy component. Check for original manufacturer markings versus third-party rebrands. Confirm the specific package variant matches your board layout requirements. Ensure compatibility with existing system clock and power supply designs before integration.

Selection Notes

Select this component only when strict compatibility with iAPX86-based legacy architectures is required. Consider the 5 MHz speed limit and 8-bit data width constraints. Evaluate if modern FPGA replacements can emulate this functionality more effectively for new designs.

Part Context

Originally part of Intel's processor lineup, this component was later associated with Altera's product catalog during corporate transitions. It represents a specific era of microprocessor technology, distinct from Altera's primary focus on programmable logic devices like FPGAs.
