About the SD186ER
Demonstration Board
1.2
The AMD SD186ER Demonstration Board is designed as an exceptionally small,
low-cost product for demons tration of the AMD
page ix for a block diagram of the board.
The SD186ER demonstration board is a stand-alone evaluation platform for the
Am186ER microcontroller. The Am186ER microcontroller integrates 32 Kbyte
of RAM along with peripherals such as 13 chip-select controllers, one
asynchronous serial port, one synchronous serial port, 32 programmable I/Os, three
timers, an interrupt controller, an d a hardware watchdog timer to increase system
functionality while reducing overall cost. The memory controller supports a
glueless connection to EPROM, Flash memory, pseudo-static RAM, and SRAM.
The Am186ER microcontroller also features an innovative bus design that frees
the processor to run at nearly twice the speed of standard 80C186 processors while
using commodity memory devices.
The SD186ER demonstr ation board is designed wi th a 104-pin Am186 expansion
interface that provides access to the Am186ER microcontroller signals. The
Am186 expansion interface facilitates prototyping with external devices by using
the SD186ER demonstration board as the minimal system core of a design.
The SD186ER demonstration board highlights the Am186ER microcontroller’s
asynchronous serial port, internal RAM, glueless interface to Flash memory, and
expansion interface to peripheral attachments. A complete description of the boa rd
can be found in Chapter 2, “Demonstration Board Functional Description”.

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 (CR2–CR9) will 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 a in 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 oth er 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.

Problem Solution
Nothing happens when
pushing the RESET
button.
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.
The computer does not
respond with the E86MON
software prompt.
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.
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
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.
pattern.
The terminal emulation
program locks up the
software or PC.
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.

ROM Space
The SD186ER demonstrat ion board is populated with an Am29F200 256-Kbyte,
55-ns Flash memory device for use by the E86MON softwar e and application code.
The Am29F200 provides support for both 8- and 16-bit accesses.
The Flash memory device is mapped to the upper region of addressable memory
at C0000h to FFFFFh. On the SD186ER demonstr atio n board, th e Flash memory
device is configured as a 128K x 16-bit wide array. The Flash memory device has
a nonsymmetrical sector configuration. Starting at the top of Flash memory, the
sectors sizes are: 16 Kbyte, 8 Kbyte, 8 Kbyte, 32 Kbyte, 6 4 Kbyte, 64 Kby te, and
64 Kbyte. The E86MON software only uses the top 16-Kbyte sector. The Flash
memory device is connected to the UCS
the microcontroller. After a valid reset, the Am186ER microcontroller fetches the
first instruction from the Flash memory device at address 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 for programming. Do not attempt to remove th e TSOP

Clock and Reset Logic
The Am186ER microcontroller can be configured for either a 4x, 1x, or ½x clock
mode. As configured on the SD186ER demonstration board, the microcontroller
is in a 4x clock mode. The input is generated by a 12.5-MHz fundamental mode
crystal (Y1) that is connected to the X1/X2 inputs of the microcontroller, resulting
in a 50-MHz system clock.
Solder pads are provided on the board to enable 1x and ½x clock modes. When
installed, R4 connects CLKSEL1
These pads are normally unpopulated. Yo u may install 100-k
one of the two positions to enable 1x or ½x clock mode (see Table 2-2).
NOTE: Refer to the Am186TMER and Am188TMER Microcontrollers Data Sheet
for detailed information on clock modes.
System reset is controlled by a voltage supply superviso r (TI TL7705ACD, U1).

Power Supply
When used as a stand-alone board, the SD186ER demonstration board requires an
input power supply o f 5.0 V DC, ±5%, 250 mA. The 3.3-V supply for the micro controller
is provided by the low drop-out voltage regulator U5.
When adding componen ts to t he SD 186ER dem onstr ation board via th e Am186
expansion interface, additional p ower may be necessary.
The power supply connector is a 5.5-mm barrel connector where the center post
and the outer ring is GND, as shown in Figure 2-6.
