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
- 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
