GETTING STARTED

4.Apply power to the host PC and the evaluation board.

When power is applied to the board, the message “i186 Ex 3V/5V EV” should appear across the LCD display. This message indicates board initialization is complete. If the message does not appear, press the reset button (S1).

Connect one end of the standard 9-pin AT-type serial connector to header P1 on the evaluation board. Connect the other end to the COM1 port of the host computer. (You can use COM2 if you need to, but you’ll have to specify COM2 when you run the Monitor Software.) The PC and board communicate at 9600 baud.

After connection to the PC, the processor may appear to be held in the reset state. The reason this occurs is that one of the host signals is used to reset the board. This signal may be active prior to invoking the ECM86 host software on the PC. The PC and board communicate at 9600 baud.

5.Insert the ECM-86 floppy disk provided with your kit in the floppy drive on the host PC. You can run the ECM86 program directly from the diskette or copy the contents of the diskette to your hard drive.

6.At the DOS prompt, change to the floppy disk drive (or to the directory to which you copied the files in the previous step) and enter this command:

ECM86

After a moment, the PC should display the ECM86 monitor screen.

Complete information on using the monitor software is located in Chapters 4 and 5.

The 80C186EC, on the other hand, is a more advanced version, offering enhanced performance metrics with faster clock speeds and improved processing capabilities, making it ideal for applications that require more computational power.

The 80L186EC shares similarities with the 80L188EC but is enhanced further for various low-power applications, especially where battery life is crucial. With a maximum clock speed of 16 MHz, it excels in scenarios demanding energy-efficient processing without sacrificing performance.

In contrast, the 80C186EB and 80L186EB are optimized versions that bring additional features to the table. The 80C186EB operates at higher clock speeds, coupled with an extended instruction set, enabling it to handle more complex tasks and run sophisticated software. These enhancements allow it to serve well in environments that require reliable performance under load, such as data acquisition systems or advanced control systems.

The 80L186EB is tailored for specific low-power scenarios, integrating Intel's sophisticated low-power technologies without compromising on speed. Utilizing advanced process technologies, these chips benefit from reduced heat output and extended operating life, a significant advantage in embedded applications.

Overall, these microprocessors showcase Intel's commitment to innovation in 16-bit processing, marked by their varying capabilities and power profiles tailored to meet the demands of diverse applications, from industrial systems to consumer electronics. Their legacy continues to influence subsequent generations of microprocessor designs, emphasizing performance, energy efficiency, and versatile applications in computing technology. As such, the Intel 80C186 and 80L188 families play a crucial role in understanding the evolution of microprocessor technology.
