AVR-USB-JTAG OPTOISOLATED USB JTAG DONGLE FOR PROGRAMMING AND EMULATION

FEATURES

• program ande debugs all AVR flash microcontrollers which have JTAG and are supported by ATJTAGICE, AVR-JTAG-USB is completely analog of ATJTAGICE (AVR Studio thinks it works with original ATJTAGICE). Note this is not AT-JTAGICE-MK2 if you want to work with the newer devices or with debug wire this JTAG will not do the job.
• optoisolated, so you can debug target boards directly connected to mains 120/220VAC (take care when work with high voltages!)
• no need for external power supply as takes power from USB port
• works with targets Vcc 3.0-5.0V
• uses Atmel's 2x5 pin JTAG connector layout (DIFFERENT FROM ICSP CONNECTOR layout!)
• works with AVR STUDIO for programming, real time emulation, debugging, step by step program execution, breakpoints, memory dump etc everything all high priced emulators do
• full emulation of all analog and digital functions, full JTAG programming support
• upgradable via AVR STUDIO
• require USB-A male type cable, i.e. you should have USB-A male to USB-A male cable to connect to your computer
• dimensions 50x40 mm (2x1.6") + 20 cm (8") cable

DOCUMENTS:

• avr-usb-jtag.pdf user guide
• AVR-JTAG-USB - How to install and use guide
• Note: AVR Studio have bug and when do upgrade your virtual COM port should be COM1 or COM2.
• AVR-JTAG firmware upgrade for the very first lot of AVR-JTAG (no -L suffix), all JTAGs shipped after 01.01.2004 are with fixed bootloader and will upgrade automatically via AVR-STUDIO

HARDWARE:

• AVR-JTAG connector(top view)
• Note: AVR-USB-JTAG needs power from target, this means PIN.4 and PIN.7 of JTAG connector should be wired to target board VCC!

SOFTWARE:

• AVR STUDIO for programming and emulation. IMPORTANT NOTE: AVR Studio 4.13 have bug and the fuses are not read correctly. On our request to Atmel support they confirm the bug and they suggest to fix this bug by "AVR Studio 4.13 SP2 JTAGICE Fix"available from http://www.atmel.no/beta_ware/
• FT232 drivers for your OS download and install to may work with AVR-JTAG-USB via the virtual COM port and AVR Studio
