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,

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:
