Description: AVR-USB-JTAG has all the power of the original AVR-JTAG plus the flexibility of a USB interface. This is a low-priced equivalent of the much more expensive JTAGICE, with a handy and safe optically isolated USB interface. Use it to debug and emulate many of the Atmel processors!
Programs all AVR flash microcontrollers which support the JTAG interface
Complete drop-in replacement of AVR-JTAGICE (AVR Studio thinks it is the original JTAGICE)
Optoisolated interface allows safe debugging of high voltage or high power target boards
Works with low power targets: Vcc 3.0-5.0V
Uses Atmel’s 2×5 pin JTAG connector layout – this is different from the ICSP connection. Please see layouts for more information.
Works with AVR Studio for programming, real time emulation, debugging, step by step program execution, breakpoints, memory dump, etc. Everything high priced emulators do and more!
Full emulation of all analog and digital functions – full JTAG programming support
Upgradable via AVR Studio
Dimensions: 50×40 mm (2×1.6″) + 20 cm (8″) cable
Does NOT power the target device
Please note that AVR-USB-JTAG needs power from the target, which means that PIN.4 and PIN.7 of the JTAG connector should be wired to the target board VCC! This is a requirement due to the optoisolation circuit.
ATMEL does not support this product (and the original Atmel JTAG ICE mkI) in AVR Studio 5 and ATMEL Studio 6 and ATMEL Studio 7.
Recommended software environments: Atmel Studio 4; AVRDUDE; AVaRICE
