About the SD188ES/SD188EM

Demonstration Board

The AMD®SD188ES/SD188EM Demonstration Board is designed as an

exceptionally small, low-cost product for demonstration of the AMDAm188ES

and Am188EM microcontrollers. See page ix for a block diagram of the board.

The SD188ES/SD188EM demonstration board is a stand-alone evaluation

platform for the Am188ES or Am188EM microcontroller. The Am188ES and

Am188EM microcontrollers integrate peripherals such as 12 chip-select

controllers, serial controllers, 32 programmable I/Os, three timers, an interrupt

controller, and watchdog timer to increase system functionality while reducing

overall cost. The memory controller supports a glueless connection to SRAM,

EPROM, Flash memory, and pseudo-static RAM. The Am188ES and Am188EM

microcontrollers also feature an innovative bus design that frees the processor to

run at nearly twice the speed of standard 80C188 processors while using

commodity memory devices.

TheSD188ES/SD188EM demonstrationboardisdesigned witha 104-pinAm188

expansion interface that provides access to the Am188ES and Am188EM

microcontrollers signals. The Am188 expansion interface facilitates prototyping

with external devices by using the SD188ES/SD188EM demonstration board as

the minimal system core of a design.

The SD188ES/SD188EM demonstration board highlights the Am188ES and

Am188EM microcontrollers’ serial ports, glueless interface to SRAM and Flash

memory, and the expansion interface to peripheral attachments. A complete

description of the board can be found in Chapter 2, “Demonstration Board

Functional Description”.

1.1

Theory of Operation

The SD188ES/SD188EM demonstration board demonstrates the basic processor

functionality and features of the Am188ES and Am188EM microcontrollers, and

the simplicity of their system design. As a stand-alone platform, the board enables

you to test the Am188ES and Am188EM microcontrollers’ performance and

functionality. The minimal number of components on the board exhibits the

integration present in the processor.

Demonstration Board Features

The SD188ES/SD188EM demonstration board provides the following features:

• Am188ES or Am188EM 40-MHz microcontroller

•E86

™

family boot monitor (E86MON) board-resident utility

Information on invoking and using the E86MON software is provided in the

E86MONTM Software User’s Manual included in your kit.

• 128 Kbyte SRAM

• 128 Kbyte Am29F010-70 Flash memory

• Am188 104-pin expansion interface

• Two RS-232 serial ports with DB-9 connectors

Please note that the Am188EM microcontroller provides one asynchronous

serial port. Thus, when the board is populated with the Am188EM

microcontroller, only one serial port is featured.

• Activity LED indicators for PIO signals

• Power-on LED indicator

• Reset circuitry

Board Installation

1. Removetheboardfromtheshippingcarton.Visuallyinspecttheboardtoverify

that it was not damaged during shipment.

!CAUTION: As with all computer equipment, the

SD188ES/SD188EM demonstration board may be

damaged by electrostatic discharge (ESD). Please take

proper ESD precautions when handling any board.

2. Connect the demonstration board’s DB-9 serial port (either P1 or P0 on the ES

version of the board; P1 on the EM version of the board) to an available COM

port. Use the serial cable included in the SD188ES/SD188EM demonstration

board kit and note that a DB-9 to DB-25 serial connector adapter is provided

if your host system requires it. The pinout of the demonstration board’s serial

connector is shown on page 2-9.

3. Connect the power supply to the barrel connectoron the SD188ES/SD188EM

demonstration board.

4. Applypowertotheboardbyconnectingthepowersupplytoanelectricaloutlet.

Once the board is powered up, the LEDs (CR3-CR10) should flash in an

oscillating pattern.

!CAUTION: If using your own power supply, ensure that

it is a 5-V supply with the proper polarity (see page 2-14).

Using a 9-V supply will permanently damage the board.

5. Invoke the terminal emulation program at 19200 baud, no parity, 8 data bits, and 1

stop bit; enable the software flow control (Xon/Xoff), if supported.

6. Reset the board by depressing and releasing the RESET switch (see location in

Figure 2-1 on page 2-3). The LEDs on the board (CR3-CR10) will again flash in

an oscillating pattern for three seconds, as they did upon power up.

During the three-second period while the LEDs are oscillating, type an ain the

terminal window to ensure that the E86MON software uses the correct baud rate.

When the E86MON software receives an a, it adjusts its baud rate (if necessary)

and displays the welcome message and prompt.

If you type a character other than an a, or type no character at all, the E86MON

software still displays the welcome message and prompt, but may be using an

incorrect baud rate. Depressing and releasing the RESET switch gives you another

opportunity to type an a.

7. To display the version of the E86MON software and the commands available, type

?and press Enter.

For detailed information on using the E86MON software, refer to the E86MONTM

Software User’s Manual included in your manual.
