Features and Applications of AVR Dragon

For developing low cost tools for 32-bit and 8-bit Avr devices, the AVR Dragon has set more improved standards for low cost development with OCD (On Chip Debug) capability. It is capable of performing symbolic debug on different devices with JTAG, SPI, PDI, high voltage serial programming Wire Models, Parallel Programming. It also supports debugging on PDI, SPI and JTAG interfaces. 

 

Key Features

Here are some of its features:

• On-board 128kB SRAM for fast statement-level stepping
• Supports up to 3 hardware program breakpoints or 1 maskable data breakpoint
• Robust level converters support 1.8V to 5.5V target operation
• Supports up to 32 software breakpoints
• Uploads 256Kb code in ~60 seconds using JTAG interface
• Firmware upgradeable for supporting future AVR devices
• Full-speed USB 2.0 compliant host interface
• It is powered by USB and can act as a source of power to other external targets
