Description:

AVR mkII Lite is the cut down version of ATMEL JTAGICE mkII, it only supports debugging with debugWIRE and ISP
programming (ISP supports all the devices that mkII supports: AVR parts with JTAG or debugWIRE interface).  It is
convenient to debug the code running inside AVR devices such as m48/88/168, tiny2313, and greatly improves the
development speed.

Version 2 (V2) now uses the same USB chip as in the original JTAGICE mkII, and also supports JTAG programming as well
as AVR32 programming and debugging.  You need to use an ISP2JTAG adapter (optional, shown below) in case of doing JTAG
programming.  The same ISP2JTAG adapter needs to be used when you deal with AVR32 devices.
Protocols Implemented:

  • Fully implemented JTAG mkII  programming protocol, thus truely supports JTAG programming AVR devices with
    JTAG interface (you need to use our KEE JTAGICE mkII to do JTAG debugging !);
  • Fully implemented debugWIRE protocol, thus truely supports debugging AVR devices with debugWIRE interface;
  • Fully implemented ISP mkII protocol, thus truely supports programming AVR devices with JTAG & debugWIRE ports;
  • Supports debugging AVR32 devices, including UC3 series and AP7000 series;
  • Supports firmware upgrade, we will provide the firmware (please check this website for firmware upgrade);
  • Supports wide target voltage ranges: 1.8V - 5.5V, has implemented a superb interface protecting hardware;
  • The speed of ISP and JTAG programming has been fully optimized and runs even faster than that of Atmel mkII.

Supported Devices under AVR Studio 4.14:
(Under JTAG interface, you will be able to do ISP as well as JTAG programming, this V2 supports both ISP and
debugWIRE functions for those debugWIRE equipped AVR devices)

The main features are:

  • Supports debugging via debugWIRE and ISP programming supports all AVR device with JTAG or debugWIRE
  interfaces.  V2 also supports JTAG programming and AVR32 programming and debugging (ISP2JTAG adapter is
   needed for JTAG programming and AVR32 debugging);
  • Connects to PC via USB interface, takes power from USB port (but does NOT provide power to target board), thus
  no external power supply is needed.
  • Connects to target board via standard ISP 10-pin interface;
  • Firmware can be upgraded in AVR Studio (the firmware file may be downloaded from our website);
  • Supports various Vcc of target board from 1.8V-5.5V, can debug low voltage AVR devices (those with suffix V
  in the part number).  This AVR mkII Lite uses standard 10-pin ISP connector, the pin definition is as the following:
This is very useful for switching between ISP mode and debugWIRE mode: mkII Lite uses ISP to enable the devices’
debugWIRE functionality, then begins debugging without switching the interface connection cable. After debugging, it can
use debugWIRE to re-enable ISP functionality.
*Note that ATmega128 has no support for the BREAK instruction.
The list is updated as new versions are released. Please check www.atmel.com for the latest information.

One KEE JTAG mkII V2;
