The AMD® SD186ED Demonstration Board was designed as an exceptionally
small, low-cost product for demonstration of the AMD Am186
microcontroller. See page ix for a block diagram of the board.
The SD186ED demonstration board is a stand-alone evaluation platform for the
Am186ED microcontroller . The Am186ED microcontroller integrates peripherals
such as twelve 16-bit memory chip-select controllers; serial controllers; 32
programmable I/Os, three timers, an interrupt controller, and a watchdog timer to
increase system functionality while reducing overall cost. The memory controller
supports a glueless connection to SRAM, DRAM, EPROM, Flash memory, and
pseudo-static RAM. The Am186ED 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 SD186ED demonstration bo ard is designed with a 104 -pin Am186 expansion
interface that provides access to the Am186ED microcontroller signals. The
Am186 expansion interface facilitates prototyping with external devices by using
the SD186ED demonstration board as the minimal system core of a design.
The SD186ED demonstration board highlights the Am186ED microcontroller’s
serial ports, glueless interface to DRAM and Flash memory, and the expansion
interface to peripheral attachments. A complete description of the board can be
found in Chapter 2, “SD186ED 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 (D1-D8) 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 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.

Reset the board by pressing the R E SET switch and
typing an a while the LEDs are flashing in an

power, check the cables, etc.
Check the baud rate setting for the terminal
emulation software. It should be set to 19200. Also
check the word length (8), stop bits(1), and 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 from the incorrect serial port.
The power LED does not
turn on with power.
Immediately disconnect the power supply. Ensure
that the polarity of the power connector is correct.
This is a very serious fail u re of t he har dware. If the
power source is connected incorrectly, the board will
be permanently damaged.
There is a problem you

Layout and Placement
The design of the SD186ED demonstration bo ard emphasizes ease of use and small
size. Refer to Figure 2-1 on page 2-3 for board layout and component placement.
The SD186ED demonstration board has the Flash and DRAM memory devices
directly below the processor (U3, U4). This placement k eeps 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 above 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-supp ly 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 board features two serial ports (P1 and P2), which are driven by the two
asynchronous serial interfaces on the Am186ED microcontroller.
The SD186ED demonstration board supports the AMD Am186ED
microcontroller. The board is shipped with an Am186ED microcontroller that
operates at 40 MHz. Although not supported by the on-board crystal, the Am186ED
microcontroller is also availabl e in 20-, 25-, and 33-MHz oper ating frequencies.
The Am186ED microcontroller i s designed to meet the most common requirements
of embedded products developed for the office automation, mass storage,
communications, and general embedded markets. Specific applications include
disk drive controllers, hand-held and desktop terminals, fax m achines, line cards,
printers, photocopiers, feature phones, cellular phones, PBXs, multiplexers,
modems, and industrial control. Refer to the Am186Sheet for more information on the specific features of the Am186ED
microcontrollers.
See Figure 2-2 on page 2-5 for a block diagram detailing the Am186ED
microcontroller’s functionality.

ROM Space
The SD186ED demonstration board contains on-boar d ROM space for use by the
E86MON software and application code. This ROM space is implemented as an
Am29F400 70-ns Flash memory.
The Flash memory is mapped to the upper region of addressa ble memory at 80000h
to FFFFFh. This range represents the top sector in the Flash memory. The Flash
memory is organized as 25 6K x 16 bits and is connected to the UCS
Chip Select) signal of the microcontroller. After a valid reset, the Am186ED
microcontroller fetches the first instruction from the Flash memories by asserting UCS
and driving the a ddres s bus with the val ue FFFF 0h.
The E86MON software enables you to program the Flash memory 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
memories. Do not attempt to remove the TSOP Flash or DRAM devices (U3 and
U4) because doing so may cause damage to the board.
DRAM
The SD186ED demonstration board utilizes DRAM for its read/write storage. The
board provides 256 Kbyte of DRAM using a 70-ns device that is mapped from 0h
to 3FFFFh. The DRAM device is organized as 256K x 16 bits and is attached to
the LCS

RS-232 Serial Ports
The SD186ED demonstration board provides two on-board RS-232 serial ports
(P1, P2) that are directly driven by the Am186ED microcontroller . The serial ports
are equipped with DB-9 DCE connectors. The pin assignment for the DB-9
connectors is shown in Figure 2-3 on page 2-7.
Traditionally, PCs have Data Terminal Equipment (DTE) ports which connect
directly to the Data Communication Equipment (DCE) port on the SD186ED
demonstration board. A null modem cable is not required to connect a DTE port
with a DCE port.
The RS-232 specification calls for signals that are driven at non-TTL levels. Singlechip RS-232 driver/receiver devices (MAX232, U5 and U6) are use d to convert to
and from the required voltages.

The Am186ED microcontroll er can be configured for eit her 1x or ½x clock mode.
As configured on the SD186ED demonstratio n board, the microcontroll er is in 1x
clock mode. The input is generated by a 40-MHz fundament al mode crystal (Y1)
that is connected to the X1/X2 inputs of the microcontrollers, resulting in a 40-MHz
system clock.

The SD186ED demonstration board supports the PC/104 form-factor expansiontype connector for additional prototy ping and testing. The traditional PC/104
signals are not present on the board; however, the Am186 expansion interface
enables you to attach wirewrap or prototype boards that have the same standard
physical interface. The pinout of the expansion interface is shown in the figures
that follow.
The SD186ED demonstration board uses on-board, LED indicators to show
activity on the upper eight programmable I/O (PIO) signals from the Am186ED
