This AVR in-system debugger and programmer supports programming via the AVR ISP interface or in-circuit debugging/programming via the AVR JTAG or DebugWire interfaces. The unit is the 100% functional equivalent of the Atmel JTAGICE mkII and supports all chips supported by the Atmel Studio software and Atmel's JTAGICE mk2.
The debugWIRE interface is used on smaller pin-count AVR chips and uses the Reset line for electrical connection, hence you do not have to sacrifice I/O capabilities to take full advantage of the On-Chip-Debug system.
The AVR JTAGICE mkII comes with a set of target cables that allow you to connect the unit to a 2×5 JTAG or 2×5 and 2×3 ISP or DebugWire interface. A cable with flying leads is provided also, for use with non-standard target pinouts. The AVR JTAGICE mkII can be connected to a PC either via USB or RS232 — both a USB and an RS232 cable are provided. A power switch on the back of the unit allows for powering the unit on and off without having to disconnect it from the USB.
The JTAGICE mk2 is able to operate using an external power supply or it can be powered directly from the USB connector. An internal switch will by default select the power from the external power supply. However, if this is not connected, or the external power supply drops below a usable level, the power will be taken from the USB (if connected). If the AVR ICE mkII is powered from the USB only, it's required that the USB can deliver minimum 500mA (Self-Powered Hub). It's recommended to power up the target before the AVR ICE mkII is powered.
For more details on connecting to a target board via JTAG, ISP or DebugWire, read the Atmel AVR Studio Help entry "AVR Tools User Guide" for the JTAGICE mkII. Please make sure to read that chapter to understand which of the included adapters needs to be used in ISP mode.
This unit does not ship with any software or documentation. Download the latest version of the Atmel Studio IDE from the Atmel website. That software (previously called AVR Studio) includes the necessary USB driver for this unit.
Be sure to read the JTAGICE MKII user documentation, which can be accessed via the Atmel Studio Help Menu → AVR Tools Guide → JTAGICE MKII User's Guide.
JTAG, ISP and DebugWire Connections The unit comes with a 2×5 (10-pin) ribbon cable attached, which is used for JTAG mode. Also included with the unit are additional short cable adapters: a 2×5 male to female adapter for standard 2×5 (10-pin) ISP connections, a 2×5 male to 2×3 female adapter for 6-pin ISP connections, and a 2×5 to flying female leads adapter for nonstandard connections. The ISP adapters are also used when working in DebugWire Mode. Do not connect the 2×5 ribbon cable that is attached to the JTAGICE directly to the target for ISP and DebugWire connections; those require the use of the included adapter, because the 2×5 pinout is different between JTAG and ISP.
