Atmel releases on-chip debug emulator

Atmel has unveiled the AVR One, an emulator for on-chip debugging and programming of all AVR and AVR32 microcontrollers, now available from Nu Horizons Electronics.

The emulator speeds up programming and supports non-intrusive observation and logging of how the embedded system performs.

This allows the software engineer a clear view of real-time system behaviour, without affecting or modifying the real-time characteristics of the microcontroller.

The latest in Atmel's line-up of on-chip debug adapters, AVR One has a 128MB internal trace buffer and supports buffered or streaming high-speed trace for the AP7 and UC3 families.

It also supports high-speed ISP, JTAG and PDI programming and JTAG, debugWire, PDI and Nexus class 2+ (AVR32UC) and class 3 (AVR32AP) debugging.

Nexus debugging features allow: flow control, hardware and software breakpoints, data breakpoints, read/write access across the memory map, live connection to the application with no interference and a real-time program, data or ownership trace capability.

AVR One has a USB 2.0 high-speed host interface.

It also supports features like JTAG scan chain, and has a target voltage range of 1.6V to 5.5V.

The OCD communication clock range is 32kHz to 33MHz.

To support the AVR One on-chip debugger, Atmel has released version 2.0 of its AVR32 Studio project manager and debugger.
