3.4. Connecting to a PDI Target
The recommended pinout for the 6-pin PDI connector is shown in Figure 4-11.
Connection to a 6-pin 100-mil PDI header
Use the 6-pin 100-mil tap on the flat cable (included in some kits) to connect to a standard 100-mil PDI
header.
Connection to a 6-pin 50-mil PDI header
Use the adapter board (included in some kits) to connect to a standard 50-mil PDI header.
Connection to a custom 100-mil header
The 10-pin mini-squid cable should be used to connect between the Atmel-ICE AVR connector port and
the target board. Four connections are required, as described in the table below.
Important:
The pinout required is different from the JTAGICE mkII JTAG probe, where PDI_DATA is
connected to pin 9. The Atmel-ICE is compatible with the pinout used by the Atmel-ICE,
JTAGICE3, AVR ONE!, and AVR Dragon
™
products.

3.5. Connecting to a UPDI Target
The recommended pinout for the 6-pin UPDI connector is shown in Figure 4-12.
Connection to a 6-pin 100-mil UPDI header
Use the 6-pin 100-mil tap on the flat cable (included in some kits) to connect to a standard 100-mil UPDI
header.
Connection to a 6-pin 50-mil UPDI header
Use the adapter board (included in some kits) to connect to a standard 50-mil UPDI header.
