Connecting Atmel-ICE to targets

Kanda has been supplying a wide range of programming products for many years. We have merchandise for beginners and more complex tools for experts. That includes Atmel-ICE, one of the most powerful development tools for microcontrollers. If this is the kind of technology you are looking for, you have come to the right place.

Atmel-ICE is a robust development utensil that can handle programming and debugging for a huge range of different microcontrollers. The design is completely compatible with Atmel studio. It also supports multiple clock frequencies and baud rates. So that you know how to properly use it, we are going to tell you how to connect it to various targets.


The Atmel-ICE probe comes with a pair of 50-mil 10-pin JTAG connectors. They are accessible on the tool’s front enclosure. Each connector is electrically connected directly. But, they conform to two separate pinouts. These would be the ARM Cortex Debug header and JTAG header.

With the connector, you need to pick it to suit the target board’s pinout. You should not base it on the target MCU type. For instance, a SAM gadget that is in an AVR STK600 Starter Kit needs to use the AVR header. Luckily, there is a wide choice of adaptors and cables to use.

JTAG targets

When you are designing an application PCB that includes an AVR alongside the JTAG interface, you need to use a certain pinout. The TDI, TMS, and TCK all need to link to the target device from the Atmel-ICE. As for the TDO, it is the other way around. It is possible for the Atmel-ICE to connect to 50-mil and 100-mil variations of the pinout.

As for designing a PCB application that includes a SAM device with the JTAG interface, you also need a particular set up. On side one you need TCK, TDO, TMS, (NC), TDI, and AVR in that order. For side two, it is GND, VCC, /REST, (TRST), GND, and JTAG.

An aWire target

This interface only demands one data line, as well as GND and VCC. On the target, this is the nRESET line. Saying this, the debugger makes use of the JTAG line as the data line. The recommended pinout for your 6-pin aWire connector is to have (RESET_N) DATA, (NC), and (NC) on side one. For side two, it is VCC, (NC), and GND.
