IS80C86-2

Microprocessors Overview

The IS80C86-2 is a high-performance 16-bit CMOS microprocessor manufactured by Harris Corporation. It operates at a maximum clock frequency of 8 MHz and features a 20-bit address bus for direct memory addressing capability. The device utilizes a self-aligned silicon gate CMOS process, ensuring low power consumption with static operation characteristics. It provides full TTL compatibility and supports industry-standard NMOS 8086 hardware and software designs. The component is available in various package options including ceramic and plastic configurations suitable for industrial applications.

Microprocessors Feature Summary

• Completely static CMOS design enabling low power operation
• Full compatibility with existing NMOS 8086 hardware and software
• Supports multiprocessing and large system applications via maximum mode

Microprocessors Applications

• Multiprocessing systems
• Industrial control environments
• Embedded computing applications requiring 8086 compatibility

Microprocessors Procurement Notes

Verify the specific suffix designation to confirm the exact operating temperature range and package material, as Harris offers variants such as CS (commercial) and MS (military). Confirm lead times and availability status directly with authorized distributors or Harris representatives, as this legacy component may have limited stock. Ensure compliance with relevant environmental regulations if RoHS compliance is required for the specific revision.

Microprocessors Selection Notes

Select the IS80C86-2 when a 16-bit architecture with 8 MHz performance is required for legacy system upgrades. Consider the commercial temperature range variant for standard industrial use. Evaluate the need for minimum or maximum mode configuration based on system complexity. Verify that the chosen package type matches the PCB footprint and thermal requirements of the target application.

Microprocessors Part Context

The IS80C86 series belongs to the Harris 80C86 family of 16-bit microprocessors. These components are designed as CMOS replacements for the original NMOS 8086 CPU. The series includes variants like the CS80C86 and IR80C86, differing primarily in temperature ratings and packaging. Harris Corporation developed these processors to offer improved power efficiency while maintaining pin and instruction set compatibility with established Intel architectures.
