voltage side of the on-board level converters. At the heart of the Atmel-ICE main board is the Atmel AVR
UC3 microcontroller AT32UC3A4256, which runs at between 1MHz and 60MHz depending on the tasks
being processed. The microcontroller includes an on-chip USB 2.0 high-speed module, allowing high data
throughput to and from the debugger.
Communication between the Atmel-ICE and the target device is done through a bank of level converters
that shift signals between the target's operating voltage and the internal voltage level on the Atmel-ICE.
Also in the signal path are zener overvoltage protection diodes, series termination resistors, inductive
filters and ESD protection diodes. All signal channels can be operated in the range 1.62V to 5.5V,
although the Atmel-ICE hardware can not drive out a higher voltage than 5.0V. Maximum operating
frequency varies according to the target interface in use.
5.4.2. Atmel-ICE Target Connectors
The Atmel-ICE don't have an active probe. A 50-mil IDC cable is used to connect to the target application
either directly, or through the adapters included in some kits. For more information on the cabling and
adapters, see section Assembling the Atmel-ICE
5.4.3. Atmel-ICE Target Connectors Part Numbers
In order to connect the Atmel-ICE 50-mil IDC cable directly to a target board, any standard 50-mil 10-pin
header should suffice. It is advised to use keyed headers to ensure correct orientation when connecting
to the target, such as those used on the adapter board included with the kit.
The part number for this header is: FTSH-105-01-L-DV-K-A-P from SAMTEC.
