Mid-range in-circuit debugger and programmer for Atmel 8-bit and 32-bit AVR microcontrollers with on-chip debugging for source level symbolic debugging, NanoTrace (if supported by the device) and device programming.

JTAGICE3 supports the following programming modes:
 

• SPI
• JTAG
• PDI
• aWire

It also supports debugging using the following interfaces:
 

• debugWIRE
• JTAG
• PDI
• aWire

Features:

• Supports a large number of AVR devices
• Supports up to 3 hardware program breakpoints or 1 maskable data breakpoint (depending on the OCD module on the AVR device)
• Supports symbolic debug of complex data types including scope information.
• Supports up to 128 software breakpoints
• Level converters support 1.8V to 5.5V target operation
• Uploads 256Kb code in ~ 15 seconds (XMEGA using JTAG interface)
• Hi-Speed USB connection to host PC Firmware upgradeable for supporting future AVR devices
• Supports NanoTrace (depending on the OCD module on the AVR device; uses target device's memory)
• USB powered.
