STK600-RC064SAM-72
Description
The Atmel® STK®600-RC064SAM-72 (STK600-RC72) is a routing card to
support the 64-pin version of the Atmel SAM D20 ARM® Cortex™-M0+ based
microcontroller on STK600. The STK600 does not support programming of
the SAM D20. However, it does work as a breakout board for IO-pins and
programming interface, as well as being able to power the device and provide
clock signals.

1. Getting Started
1.1 Card Stack
The STK600-RC064SAM-72 must be used together with an STK600. In addition a socket board is required.
Depending on the package type of the device, either of STK600-TQFP64-2 and STK600-QFN64 can be used.
See the STK600 User Guide for instructions on assembling the card stack.
Once the card stack is assembled, the STK600 can be powered. The status LED should be steady green. If it
is blinking orange, it might be necessary to let Atmel Studio update the card stack information on the STK600.
This is done automatically when connecting to STK600 in the programming dialog.
1.2 Board Settings
The programming dialog of Atmel Studio is used to set the voltages and clock frequency. Since programming
of the SAM D20 is not supported by STK600, it will not show in the device list. Therefore, when connecting
to STK600 in the programming dialog, it is necessary to select a different device than SAM D20. Any device
and interface (e.g. AT32UC3A0128 and JTAG) from the lists will work for setting the voltage and clock. After
connecting, go to board settings to access the voltage and clock settings. Move the sliders and click "Write" to
change the values. Note that all voltages are limited to 3.6V.

1.3 Connections
The SWD interface of the SAM D20 is routed to the 10-pin JTAG connector and the 6-pin ISP connector of the
STK600. The pinout is shown in the figure below, in addition to the pinout for the SAM-ICE™.

Figure 1-2. Tool Pinout
It is necessary to use single wires to connect the SAM-ICE to the STK600 headers. The picture below is a
reference for making the connections.
