The MG80286-10/B, manufactured by Rochester Electronics, is a 16-bit microprocessor that is a successor to the Intel 8086 and 8088 processors. Rochester Electronics specializes in manufacturing end-of-life and mature products, ensuring continued availability of this important processor.

Applications:

• Industrial control systems
• Embedded systems requiring 16-bit processing
• Retro computing projects and repairs
• Legacy computer systems
• Automated testing equipment

Features:

• 16-bit Architecture: 16-bit data bus and address bus (expanded beyond the 8086).
• Clock Speed: 10 MHz operation.
• Memory Management: Supports protected mode operation with memory management capabilities.
• Addressing: Up to 16 MB of addressable memory.
• Instruction Set: Upward compatible with the 8086 instruction set, with added instructions for protected mode operation.
• Package: Typically available in a 68-pin PLCC (Plastic Leaded Chip Carrier) or PGA (Pin Grid Array) package.

Benefits:

• Extended Memory Addressing: Supports significantly more memory than its predecessors.
• Protected Mode Operation: Enables multitasking and memory protection features.
• Improved Performance: Higher clock speed and enhanced instruction set compared to the 8086.
• Continued Availability: Rochester Electronics ensures a reliable supply of this mature product.
• Compatibility: Can run existing 8086/8088 software (in real mode).

Additional Details:

The MG80286-10/B from Rochester Electronics is often used in applications where the original Intel 80286 is no longer available or cost-effective. It provides a reliable replacement option for maintaining and extending the lifespan of existing systems. The processor supports two operating modes: real mode (compatible with the 8086) and protected mode (which provides memory protection and multitasking capabilities). Understanding the differences between these modes is crucial for programming and system configuration. Rochester Electronics reverse engineers or uses original intellectual property to produce the MG80286-10/B, ensuring it meets the original specifications.
