A80C286-12

Overview

The A80C286-12 is a static CMOS microprocessor manufactured by Rochester Electronics, LLC. It serves as the CMOS version of the NMOS 80286, designed for multiple user and multi-tasking systems. The component supports DC to 12.5MHz clock rates and features built-in memory protection for task isolation. It provides a 16-megabyte physical address space per task and includes integrated memory management capabilities.

Feature Summary

Static CMOS design optimized for low power operation
Built-in memory protection supporting operating system and task isolation
Integrated memory management mapping virtual address space into physical memory
Compatible with 80287 numeric data co-processor

Applications

Multiple user systems
Multi-tasking environments
Applications requiring program and data privacy within tasks

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm exact speed grades and package types. Confirm RoHS compliance status as historical CMOS parts may vary. Ensure the source document explicitly lists the A80C286-12 designation rather than generic family names. Check for any specific handling requirements associated with vintage semiconductor components.

Selection Notes

Select this component when a CMOS upgrade for legacy 80286 architectures is required without changing pin compatibility. It is suitable for designs needing lower power consumption compared to NMOS equivalents while maintaining identical functionality. Verify that the 12.5MHz maximum frequency meets the system timing requirements before finalizing the selection.

Part Context

Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find semiconductors. The A80C286-12 belongs to the 80286 family, originally developed for high-performance computing tasks. This part represents a continuation of supply for legacy industrial and embedded applications where original manufacturers have discontinued production.
