SAMG55J SWD/JTAG Port
The PL360G55CB-EK board includes an SWD (Serial Wire Debug) / JTAG interface port to provide
debug level access to the system-on-chip. It also embeds a serial wire trace. This connector provides the
required interface for in-circuit emulators, like the
. The SW-DP/JTAG port is a 10-
pin, dual row, 0.1-inch male connector (J7). When using the SAM-ICE, a JTAG adapter for 20 to 10 pins
is necessary, e.g.,
Important:
Note that the PL360G55CB-EK kit does not include either Atmel SAM-ICE or
Atmel-ICE JTAG emulators.
Please refer to the
for further description of the JTAG debug port.

CAUTION
The JTAG/SWD connector is not isolated from mains. Please make use of proper isolation (i.e.:
USB isolator device) if using this connector when the board is not galvanically isolated (using a
PLC Coupling design which it is not isolated from mains). Take into account the possible noise
interference that these isolators could be adding to the PLC network. For instance, you can use

mikroBUS Connector
The PL360G55CB-EK board incorporates mikroBUS add-on connectors (J5 and J6) to integrate the
board itself as a module which is able to interface with other microcontrollers or microprocessors (main
board).
The mikroBUS standard specifies the size and shape of the add-on boards, but because of special
constraints, the board exceeds those limits although keeping the smallest size model S as a reference for
the plug-in area.
The PL360G55CB-EK board is designed to operate only from the +5V power supply rail of the mikroBUS
socket. Therefore, +3.3V power supply pin is not connected.
Important:
By default, J5 and J6 headers are not populated in the board. The 8-pin headers
are included in a zip bag as kit contents.
This mikroBUS standard has a pair of 1x8 male headers with the following pinout:
