Product Overview

AVR-JTAG-USB is an opto isolated USB JTAG dongle for programming and emulation. This AVR-JTAG-USB programs and debugs all AVR flash microcontrollers which have JTAG and are supported by ATJTAGICE. AVR-JTAG-USB works transparently with AVRSTUDIO as it uses USB to RS 232 driver inside and AVRSTUDIO just finds ATJTAGICE connected to the virtual COM port which FT232 driver installs. AVR-JTAG-USB allow debugging on all new computers and notebooks which have no RS 232 COM port and removes all problems which occur when unknown/uncertified USB to RS 232 port converters are used with the original RS 232 based ATJTAGICE.
  • Opto isolated, so you can debug target boards directly connected to mains 120VAC /220VAC
  • No need for external power supply before the opt coupler it as takes power from USB port
  • Works with targets Vcc 3V to 5V
  • Uses Atmel's 2x5pin JTAG connector layout
  • Works with AVR STUDIO for programming, real time emulation, debugging and etc
  • 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 PC
