Description and Introduction

16-BIT HIGH-INTEGRATION EMBEDDED PROCESSORS The **TN80C186EB25** is a microprocessor manufactured by **Intel**. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Intel  
- **Part Number:** TN80C186EB25  
- **Type:** Embedded microprocessor  
- **Architecture:** 80C186 (Enhanced 80186)  
- **Clock Speed:** 25 MHz  
- **Data Bus Width:** 16-bit  
- **Address Bus Width:** 20-bit (1 MB addressable memory)  
- **Instruction Set:** x86 (16-bit)  
- **Operating Voltage:** 5V  
- **Package Type:** Plastic Leaded Chip Carrier (PLCC)  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) depending on variant  

### **Descriptions:**
- The **80C186EB** is an enhanced version of the **80186** microprocessor, designed for embedded applications.  
- It integrates several peripherals, including timers, DMA controllers, interrupt controllers, and chip-select logic, reducing the need for external components.  
- It is commonly used in industrial control systems, telecommunications, and embedded computing.  

### **Features:**
- **Integrated Peripherals:**  
  - Two 16-bit DMA channels  
  - Three programmable 16-bit timers  
  - Programmable interrupt controller  
  - Programmable memory and I/O chip-select logic  
  - Power-saving modes  
- **Enhanced Performance:**  
  - Higher clock speed (25 MHz) compared to earlier versions  
  - Improved instruction execution efficiency  
- **Compatibility:**  
  - Binary-compatible with the 8086/8088 instruction set  
  - Supports real-time operating systems (RTOS)  

This information is based solely on Intel's documented specifications for the TN80C186EB25.

Application Scenarios & Design Considerations

16-BIT HIGH-INTEGRATION EMBEDDED PROCESSORS

Alternative Part Number

  • EE80C186EB25 --: Same 80C186EB core at 25 MHz from Intel's embedded line, drop-in compatible with identical pinout and instruction set.
  • AM80C186EB-25 --: AMD second-source 80C186EB running at 25 MHz, functionally equivalent and widely used as a direct replacement.
  • MC80C186EB25 --: Motorola 80C186EB-compatible embedded processor at 25 MHz, suitable alternative with matching bus interface and peripherals.
  • MC68SEC000AA25 --: Industry-standard 16/32-bit embedded CPU at 25 MHz with a similar bus interface; commonly used as a second-source style replacement in legacy 80186-class designs after glue-logic review.
  • W65C816S6TPG-14 --: Widely available 16-bit microprocessor with a comparable address/data bus and 5V operation, suitable as a last-resort substitute for legacy embedded control boards when exact 80C186EB compatibility is not mandatory.
