About the SD186ES/SD186EM Demonstration Board

1.1

The AMD
exceptionally small, low-cost product for demonstration of the AMD Am186ES
and Am186EM microcontrollers. See page ix for a block diagram of the board.

The SD186ES/SD186EM demonstration board is a stand-alone evaluation
platform for the Am186ES or Am186EM microcontroller. The Am186ES and
Am186EM 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 Am186ES and Am186EM
microcontrollers also feature 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 SD186ES/SD186EM demo nstration board is des igned with a 104-pin Am186
expansion interface that provides access to the Am186ES and Am186EM
microcontroller signals. The Am186 expansion interface facilitates prototyping
with external devices by using the SD186ES/SD186EM demonstration board as
the minimal system core of a design.

The SD186ES/SD186EM demonstration board highlights the Am186ES and

Am186EM 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”.

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

6. Reset t he board by depressing and releasing the RESET switch (see location in Figure
2 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 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 mess age and prompt, but may be using an
incorrect baud rate. Depressing and releasing the RESET switch gives you another
opportunity to type an a.

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 R E SET 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 should 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 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
cannot resolve.

Layout and Placement

The design of the SD186ES/SD186EM demonstration board emphasizes ease of
use and small size. Refer to Figure 2 on page 2-3 for board layout and component
placement.

The SD186ES/SD186EM demo nstration b oard has the Flash and SRAM memory
devices (U3, U4 and U7, U8) directly below the processor . Th is 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
right of the processor. Th e 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 Am186ES microcontroller .
The Am186EM 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 SD186ES/SD186EM demonstration board contains on-board ROM space for
use by the E86MON software and application code. This ROM space is
implemented as two Am29F010 70-ns Flash memory devices.

The Flash memory devices are mapped to the u pper region of addressable memory
at C0000h to FFFFFh. This range represents the top sector in both Flash memory
devices. Each Flash memory device is organized as 128K x 8 bits (eight, 16K
sectors) and is connected to the UCS
microcontroller. After a valid reset, the Am186ES or Am186EM microcontroller fetches
the first instruction from the Flash memory devices by asserting UCS
address bus with the value FFFF0h.

The E86MON software enables you to program the Flash memory devices 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 devices. Do not attempt to remove the TSOP Flash memory or
SRAM devices (U3, U4, U7, and U8) because doing so may cause damage to the
board.

RS-232 Serial Ports

The ES version of the SD186ES/SD186EM demonstration board provides two
on-board RS-232 serial ports (P0, P1) that are directly driven by the Am186ES
microcontroller. The serial ports are equipped with DB-9 DCE connectors. The
pin assignment for the DB-9 connectors is shown in Figure 2-4 on page 2-9.

The EM version of the SD186ES/SD186EM demonstration board provides one
on-board RS-232 serial port that is driven directly by the Am186EM
microcontroller. The RS-232 serial port (P1) is equipped with a DB-9 DCE
connector. The pin assignment fo r t he DB-9 conn ect or is s ho wn in Fi gu re 2-4 on
page 2-9.

The Am186EM serial port does not provide RTS and CTS support in hardware.

Traditionally, PCs have Data Terminal Equipment (DTE) ports which connect
directly to the Data Communication Equipment (DCE) port on the SD186ES/
SD186EM demonstration board. A null modem cable is not requ ired 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 used to con vert to
and from the required voltages.

interface enables you to attach wirewrap or prototype boards that have the same
standard physical interface. The pinout of the expansion interface for the SD186 ES
is shown in the figures that follow.

NOTE: The pinout of the expansion interface is identical for both the SD186ES
and SD186EM demonstration bo ards except for t he four pins shown in Table 2-2.
