• Integrates a 16-bit CPU core with built-in memory management capabilities
• Includes dedicated hardware for system timing and interrupt control
• Supports low-power operation modes for energy efficiency

Applications

• Embedded industrial control systems
• Telecommunications equipment processing units
• Office automation devices

Procurement Notes

Verify component authenticity due to potential availability from third-party manufacturers offering form-fit-function replacements. Confirm package integrity and pin compatibility before integration into existing designs. Check for RoHS compliance status as original specifications may vary depending on the production source and era.

Selection Notes

Select this component for legacy 80C186-based architectures requiring a direct replacement. Ensure the design accommodates the 68-pin PLCC footprint. Verify that the 13MHz clock speed meets the system timing requirements. Consider power supply voltage levels compatible with the specific variant's electrical characteristics.

Part Context

This part is part of the Intel/Altera 80C186EC/80L186EC family of 16-bit high-integration embedded processors. These devices were widely used in embedded systems before being succeeded by newer architectures. The TN prefix often indicates a specific manufacturer or variant within the broader ecosystem of compatible components.

Replacement Considerations

Innovasic IA186EB/IA188EB are confirmed form-fit-function replacements for related 80C186EB/80C188EB devices. Verify exact pinout and undocumented feature compatibility when substituting.
