Features:
AVR-USB-JTAG
ATMEL’s AVR JTAG ICE) is development tool
for programming, real time emulation and
debugging for AVR microcontrollers with JTAG
interface (ATmega16, ATmega32, ATMega323,
ATmega162, ATmega169, ATmega128 and all
other future to come). AVR-USB-JTAG have:
JTAG 10 pin connector (Atmel layout), status
LED, USB type A connector.
AVR-USB-JTAG
AVRSTUDIO as it uses USB to RS232 driver
inside and AVRSTUDIO just finds ATJTAGICE
connected to the virtual COM port which FT232
driver
debugging on all new computers and notebooks
which have no RS232 COM port and removes all
problems
unknown/uncertified
converters are used with the original RS232
based ATJTAGICE.
AVR-USB-JTAG is optically isolated from
USB port, so you can debug directly connected
to 120/220VAC mains targets.
AVR-USB-JTAG allows access to all the
powerful features of the AVR microcontroller.
All AVR resources can be monitored: Flash
memory, EEPROM memory, SRAM memory,
Register File, Program Counter, Fuse and Lock
Bits, and all I/O modules. AVR-JTAG also
offers extensive On-chip Debug support for
break conditions, including break on change of
Program memory flow, Program memory Break
Points on single address or address range, and
Data memory Break Points on single address or
address range.

Programming:
To work with AVR-USB-JTAG you need target
board with JTAG connector (for instance
Olimex’s
8Mhz) and AVRSTUDIO software ( you can
download from http://www.avrfreaks.net in
Tools section).
JTAG interface:
The JTAG connector is 2x5 pin with 0,1" step
and Atmel’s compatible layout. The PIN.1 is
marked with square pad on bottom and arrow on
top. JTAG signals are: 1- TCK, 2- GND, 3-
TDO, 4- VREF, 5- TMS, 6- NSRST, 7- VCC, 8-
NTRST, 9- TDI, 10- GND.

Virtual com port driver:
AVR-USB-JTAG uses FT232 USB to RS232 IC
from Future Technology devices, you must
download and install proper driver for your
computer and OS from:
