MG80C186XL-20/R

Overview

The MG80C186XL-20/R is a high-integration 16-bit microprocessor belonging to the i186 series, manufactured by Rochester Electronics, LLC. It features an 80C186 core architecture operating at a maximum clock frequency of 20 MHz. The device is implemented in CMOS technology and supports a 5V supply voltage. It is housed in a plastic leaded chip carrier package with 68 pins (LCC-68). This component serves as a direct replacement for original Intel 80C186XL processors, providing equivalent functionality within the same architectural family.

Feature Summary

• High integration level combining CPU, memory controllers, and peripheral interfaces on a single die
• Compatible with standard 80C186XL software and hardware environments
• CMOS construction ensuring low power consumption relative to NMOS predecessors

Applications

• Industrial control systems requiring 16-bit processing
• Embedded applications utilizing legacy 80C186XL codebases
• Replacement for obsolete original equipment manufacturer components in existing hardware designs

Procurement Notes

Verify that the specific lot date code and manufacturing origin meet your quality assurance requirements. Confirm package integrity upon receipt, as these are often surplus or lifecycle management parts. Ensure compatibility with your existing board design, particularly regarding pinout alignment and thermal characteristics, before finalizing procurement.

Selection Notes

Select this part when maintaining compatibility with existing 80C186XL-based systems is required. It is suitable for upgrades where performance needs remain within the 20 MHz limit. Consider it for obsolescence mitigation strategies where redesigning the system is not feasible. Verify that the LCC-68 package footprint matches your current PCB layout constraints.

Part Context

This component is part of the i186 family, originally designed by Intel. Rochester Electronics provides lifecycle support for discontinued semiconductor products. The MG80C186XL-20/R specifically addresses the need for continued availability of the 20 MHz variant of the 80C186XL processor in its original plastic leaded package format.

Replacement Considerations

Direct substitutes include the N80C186-20 and SB80C186XL-12 from various manufacturers, provided pinouts and electrical specifications align. Verify that any alternative source guarantees identical functional behavior to the original Intel specification.
