Once the ATMembase and Daughter Board are connected, the user must then install a device to be used as the
Device Under Test (DUT) for the Evaluation Kit. Please refer to Table 4-1 for supported devices for the Evaluation
kit.
When the AT21CSMK100 Evaluation Kit is shipped, there is a DUT already installed
in the Daughter Board socket and the latest version of the ATMembase firmware
programmed.
Figure 4. AT21CS01 in SOT23 Socket
Figure 4 illustrates an AT21CS01 DUT in the Daughter Board 3 lead SOT-23 socket. Note that the latch is not
closed in order to illustrate the DUT and the latch should be closed for proper DUT installation.
Due to the small size of the 3 lead SOT-23 package, it is recommended to use twee-
zers in order to properly install a DUT in the Daughter Board socket.
The firmware of the Graphical UI utilizes the AT21CS Series Reset and Discovery Response in order to determine
whether the DUT is installed correctly in the Daughter Board socket. If the Discovery Response is not seen by the
master (ATMembase), an error message is displayed in the Graphical UI stating that the DUT is not installed
properly. For more information related to DUT Discovery Response, please refer to the AT21CS Series Reset and
Discovery Application Note.
Single-Wire Protocol devices only need two pins in order to communicate (SI/O and GND). These signals can be
seen in Figure 5. Pin 5 of the H1 header is the SI/O pin and Pin 9 of the H1 header is GND. Header H1 can be
seen in greater detail in the AT21CS01 Single-Wire Daughter Board Schematic. These pins can be used to
capture Single-Wire protocol using an oscilloscope or any other tool designed to capture waveforms.

Once a DUT is installed in the Daughter Board socket, the user can then plug in the ATMembase into one of their
computers USB ports.
The use of external USB hubs can induce inconsistent ATMembase behavior. There-
fore, it is recommended to connect the ATMembase to a USB port that is directly
connected to the user’s computer when using the AT21CSMK100 Evaluation Kit.

5.1.2 Programming with USB Bootloader: Device Firmware Upgrade (DFU)
The Atmel AT90USB1287 AVR comes with a default factory pre-programmed USB bootloader located in the on-
chip boot section of the AT90USB1287. This is the easiest and fastest way to reprogram the device directly over
the USB interface. The FLIP PC Application, available for free on the Atmel website, offers a flexible and user
friendly interface for reprogramming the application over the USB bus. FLIP can be found at the following hyperlink:
http://www.atmel.com/tools/flip.aspx
The “HWB” push button is used to place the AVR into DFU mode after reset. Refer to the Atmel AT90USB1287
Datasheet for further information.
The following steps enable the ATMembase DFU mode:
1. Press and hold “HWB” button
2. Press the “RESET” button
3. Release the “RESET” button
4. Release the “HWB” button
HWBE fuse must be enabled to support DFU
The use of external USB hubs can induce inconsistent programming behavior of the
ATMembase. Therefore, it is recommended to connect the ATMembase to a USB
port that is directly connected to the user’s computer during Flip DFU programming.
For more information related to the USB bootloader and the use of FLIP software, please refer to Application Note
found at the following hyperlink:
http://www.atmel.com/Images/Atmel-8991-SEEPROM-Upgrade-Kit-FW-Using-FLIP-ApplicationNote.pdf
5.1.3 Program debugging with the Atmel JTAGICE III
The AT90USB1287 can be programmed using the specific JTAG link. This subsection will explain how to connect
and use the Atmel AVR JTAG ICE.
When the JTAGEN fuse is disabled, the four TAP pins are normal port pins, and the
TAP controller is in reset. When the JTAGEN fuse is enabled, the input TAP signals
are internally pulled high. This enables the JATG for boundary-scan and program-
ming. The Atmel AT90USB1287 device is shipped with this fuse programmed
