Overview
The TN80C186EB-16 is a CMOS high-integration 16-bit microprocessor manufactured by Rochester Electronics, LLC. It belongs to the i186 series and features an 80C186 core processor. The device operates at a maximum clock speed of 16 MHz and is housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package, also described as 84-LCC with J-Leads. It supports DRAM controllers and includes graphics acceleration capabilities.
Feature Summary
- Integrates an 80C186 core processor within the i186 family architecture
- Supports DRAM controller functionality for memory management
- Includes hardware-accelerated graphics processing capabilities
Applications
- Embedded systems requiring 16-bit processing
- Industrial control applications utilizing DRAM interfaces
- Legacy system maintenance and replacement
Procurement Notes
Verify the specific suffix and package type against original design requirements. Confirm that the PLCC-84 footprint matches the target PCB layout. Ensure compatibility with existing firmware and peripheral interfaces before integration into new or refurbished designs.
Selection Notes
Select this component when a 16-bit i186-compatible processor is required with integrated graphics and DRAM support. The 16 MHz speed suits moderate-performance embedded tasks. The PLCC-84 package dictates specific socket or surface-mount assembly considerations compared to other pin counts.
Part Context
This part is part of the extended lifecycle portfolio managed by Rochester Electronics, LLC. It serves as a source for end-of-life semiconductors originally produced by AMD. The TN80C186EB-16 maintains functional equivalence to the original 80C186EB specifications while being available through authorized secondary market channels.
Replacement Considerations
Direct substitutes include the N80C186-20 and TN80C186EB-16 variants from compatible manufacturers. Verify pinout compatibility between PLCC packages. Cross-reference datasheets to ensure identical electrical characteristics and timing parameters for seamless integration.
