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 AMDAm188ES
and Am188EM 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”.

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

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.
