Description and Introduction

16-BIT HIGH-INTEGRATION EMBEDDED PROCESSORS The **TN80C186EB-20** is a microprocessor manufactured by **Intel**. Below are its specifications, descriptions, and features based on the provided knowledge base:  

### **Specifications:**  
- **Manufacturer:** Intel  
- **Part Number:** TN80C186EB-20  
- **Core:** 80C186 (Enhanced 80186)  
- **Clock Speed:** 20 MHz  
- **Data Bus Width:** 16-bit  
- **Address Bus Width:** 20-bit (1 MB addressable memory)  
- **Instruction Set:** x86-16  
- **Operating Voltage:** 5V  
- **Package Type:** Plastic Leaded Chip Carrier (PLCC) or other Intel-specified package  
- **Technology:** CMOS  

### **Descriptions:**  
- The **TN80C186EB-20** is an enhanced version of the **Intel 80186** microprocessor.  
- It integrates several system components, including a clock generator, interrupt controller, timers, and DMA controller, reducing the need for external chips.  
- Designed for embedded applications requiring high performance and low power consumption.  

### **Features:**  
- **Integrated Peripherals:** Includes two DMA channels, three timers, and a programmable interrupt controller.  
- **Power Efficiency:** CMOS technology ensures lower power consumption.  
- **Enhanced Performance:** Improved instruction execution over the original 80186.  
- **Wide Operating Temperature Range:** Suitable for industrial applications.  
- **On-Chip Clock Generator:** Reduces external component count.  

This information is strictly factual and based on the provided knowledge base. No additional suggestions or guidance are included.

Application Scenarios & Design Considerations

16-BIT HIGH-INTEGRATION EMBEDDED PROCESSORS

Alternative Part Number

  • EE80C186EB20 --: Same 80C186EB core and 20 MHz speed grade from Intel, offered under the EE prefix ordering code; functionally equivalent with matching package and temperature options.
  • MC68SEC000AA20 --: Industry-standard 20 MHz embedded microprocessor with a similar 16-bit bus and low-power static core, widely used as a drop-in architectural alternative in legacy 80186-class designs.
  • AM186EM-20 --: AMD E86-family 20 MHz embedded controller compatible with the 80186 instruction set and peripherals, suitable as a second-source replacement for 80C186EB-based designs.
  • AM80C186EB-20 --: AMD second-source 80C186EB-compatible microcontroller at 20 MHz, widely used as a drop-in replacement for Intel 80C186EB parts.
  • 80C186EB-20 --: Base 80C186EB device rated at 20 MHz, same architecture and package family, suitable when the TN temperature/quality grade is not required.
