About the SD188ES/SD188EM Demonstration Board
1.1
The AMD® SD188ES/SD188EM Demonstration Board is designed as an
exceptionally small, low-cost product for demonstration of the AMD
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.
The SD188ES/SD188EM demo nstration board is des igned with a 104-pin Am188
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 SR AM 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 Descri ption”.

Table 1-1. Installation Troubleshooting
Problem Solution
1.1
Nothing happens when
pushing the RESET
button.
The computer does not
respond with the E86MON
software prompt.
After typing a during reset,
the terminal emulation
software displays
unreadable characters.
After a processor reset, the
LEDs do not flash in the
expected oscillating
pattern.
The terminal emulation
program locks up the
software or PC.
Sometimes it is difficult to make a good
connection when pushing the small RESET
button. If all else fails, remove the power supply
from the AC electrical outlet and disconnect and
reconnect the power supply . The LEDs will flash
in an oscillating pattern when the reset is
successful.
Reset the board by pressing the RESET switch and
typing an a while the LEDs are flashing in an
oscillating pattern. If this does not work, verify the
power, check the cables, etc.
Check the baud rate setting for the terminal
emulation software. It sh ould be set to 19200. Also
check the word length (8), stop bits (1), parity (N),
and turn off any hardware flow control.
Check that the power LED is on and the correct
voltage is supplied to the board. Ensure that the
polarity of the power connector is correct.
Check the COM port connection with the target
board. Make sure that the same COM port is
selected in the terminal emulation software. In
some PCs if the correct COM port is not specified,
the software will fail to function—it will lock in
a continuous loop waiting for an answer f rom the
incorrect serial port.
The power LED does not
turn on with power.
Immediately disconnect t he power supply. Ensure
that the polarity of the power connector is correct.
This is a very serious failure of the hardware. If
the power source is connected incorrectly, the
board will be permanently damaged.
There is a problem you
cannot resolve.

Layout and Placement
The design of the SD188ES/SD188EM demonstration board emphasizes ease of
use and small size. Refer to Figure 2-1 on page 2-3 for board layout and component
placement.
The SD188ES/SD188EM demo nstration b oard has the Flash and SRAM memory
devices (U4 and U3) directly below the processor. This placement keeps the
memory devices as close as possible to the processor to minimize noise and trace
reflections. The 40-MHz fundamental mode crystal (Y1) is located to the righ t of
the processor. The expansion interface (J2 and J3) is located at the bottom of the
board for easy connection and access. Finally, the 5.5-mm power-supply barrel
connector (J1) is positioned in the upper, left corner of the board.
The RS-232 serial interfaces are positioned on the right of the board. Please note
that the ES version of the board features two serial ports (P0 and P1), which are
driven by the two asynchronous serial interfaces on the Am188ES microcontroller .
The Am188EM microcontroller provides one asynchronous serial interface so the
EM version of the board implements the serial port with a DB-9 connector (P1).

ROM Space
The SD188ES/SD188EM demonstration board contains on-board ROM space for
use by the E86MON software and application code. This ROM space is
implemented as one Am29F010 70-ns Flash memory device.
This Flash memory device is mapped to the upper re gion of addres sable memory
at E0000h to FFFFFh. The Flash memo r y d e vice is organized as 128K x 8 bits
(eight, 16K sectors) and is connected to the UCS
of the microcontroller. After a valid reset, the Am188ES or Am188EM microcontroller
fetches the first instruction from the Flash memory device by asserting UCS
the address bus with the value FFFF0h.
The E86MON software enables you to program the Flash memory device with
specific types of hex files. Intel hex and Intel extended hex format files are
supported. This software functionality is provided to eliminate the need to remove
the Flash memory device. Do not attempt to remove the TSOP Flash or SRAM
(U3, U4, U7, and U8) memory devices because doing so may cause damage to the
board.
SRAM
The SD188ES/SD188EM demonstration board utilizes SRAM for its read/write
storage. The board provides 128 Kbyte of SRAM using one 70-ns device that is
mapped from 0h to 1FFFFh. The SR AM device is or ganized as 12 8K x 8 bits and
is attached to the LCS
