MG80C186EB-13/R

Overview

The MG80C186EB-13/R is a 16-bit microprocessor based on the Intel 80C186 architecture, manufactured by Rochester Electronics. It operates at a clock speed of 13 MHz and functions as a CMOS device with a 5.0V supply voltage. The component is housed in a PQFP80 shrink package, providing an 80-pin Quad Flat Package configuration for surface mount applications. This processor integrates core processing capabilities suitable for embedded control systems requiring 16-bit data handling.

Feature Summary

• Implements the 80C186 16-bit microprocessor core architecture
• Operates with a 5.0V I/O voltage specification
• Provides integrated RAM controller and DRAM graphics acceleration support

Applications

• Embedded control systems requiring 16-bit processing
• Industrial automation controllers
• Legacy system maintenance and replacement

Procurement Notes

Verify the specific manufacturing date code and lot traceability upon order confirmation, as Rochester Electronics supplies components from various production sources. Confirm that the PQFP80 shrink package dimensions match the target PCB footprint exactly. Ensure the 13 MHz operating frequency meets the timing requirements of the host system design before finalizing procurement.

Selection Notes

Select this component when a direct 80C186-compatible replacement is required for legacy designs. The 13 MHz speed variant offers a balance between performance and power consumption compared to higher-speed equivalents. Verify compatibility with existing memory maps and interrupt structures, as the 80C186 architecture includes specific peripheral interfaces that may differ from standard 8086 implementations.

Part Context

Rochester Electronics specializes in the sourcing and distribution of obsolete and hard-to-find semiconductor components. The MG80C186EB-13/R represents a continuation of the Intel 80C186 family, ensuring availability for long-life industrial and military applications where original manufacturer production has ceased. This part serves as a critical bridge for maintaining older electronic systems.

Replacement Considerations

Cross-reference with SB80C186XL12 or MG80C186EB-16/R for speed or package variations within the same architectural family. Ensure pinout compatibility remains identical when substituting with other 80C186 derivatives.
