2.4SETTING UP THE EVALUATION BOARD AND THE HOST PC

This section tells you how to set up the board for use with a host PC. This section assumes you won’t be using some of the advanced features of the board when you first power it up. For additional options, such as selecting 80188 evaluation mode, refer to Chapter 3, “Hardware Overview.”

1.Make sure you are in a static-free environment before removing any components from their anti-static packaging. The evaluation board is susceptible to electro-static discharge damage; such damage may cause product failure or unpredictable operation.

2.Inspect the contents of your kit. Make sure that all items are included. Check for damage that may have occurred during shipment. Contact your sales representative if any items are missing or damaged.

CAUTION: Many of the connectors on the evaluation board provide power through non- standard pins. Connecting the wrong cable or reversing the cable can damage the evaluation board and may damage the device being connected. Use extreme caution when preparing to connect cables to this product.

3.Connect the power supply. The Intel 186 EC/EB Evaluation Board operates from a 5 VDC ± 10% power supply plugged into the J2 power connector (see Figures 2-1 and 2-2). This 5 volt signal is stepped down to 3.3 volts on the board. The connector housing and contact pins provided in your kit match the power supply to the J2 connector.

To select 5 V, place a jumper on pins B and C of jumper E1. To select 3 V, place a jumper on pins A and B of jumper E1. See Figures 2-1 and 2-2 for jumper locations.

All devices on the board operate at both 3.3 volts and 5.0 volts (except the LCD display, which is hardwired to 5 volts). This option allows comparison of current consumption when running code at either voltage. Separately packaged 5 V versions of the 80C186 processor and SRAM must be installed on the board for 5 V operation.

It operates at clock speeds of up to 10 MHz and features a 16-bit architecture, providing a balance of processing power and energy efficiency. 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.
