Flash microcontroller meets USB specs
Atmel has been granted certification by the USB Implementers Forum (USB-IF) for its AT91SAM7S64 ARM-based 32bit Flash microcontroller.
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 unit is a high-end JTAG and Nexus on-chip debugger that is designed to deliver accurate monitoring of system behaviour in embedded systems built around AVR and AVR32 microcontrollers and application processors.
Faster communication between the PC and the target microcontroller speeds up the flow of debug data, and the user will notice the improved responsiveness to user input.
Programming microcontrollers with large on-chip Flash memories will be up to three-times faster than existing debuggers.
The AVR One! offers advanced real-time debugging features.
In addition to basic programming and on-chip debugging via the traditional 4-pin JTAG port, the AVR One! supports debugging via the Nexus port, an 8bit parallel port found on all AVR32 devices.
Inside the AVR32 microcontroller, the Nexus port is connected by a separate databus to all the on-chip peripherals and memories.
The separate bus allows the debugger to monitor and modify system behaviour in every part of the microcontroller without interrupting or affecting the timing of the program running in the microcontroller.
The AVR One! can be connected live to a running application without interference.
The AVR32 Nexus debug interface is connected to the AVR32 CPU's trace port.
This is a port which outputs vital statistics about CPU behaviour and the software running.
This real-time trace data is captured by the AVR One! debugger and forwarded to the PC, where the user can reconstruct the steps taken by the CPU leading up to an erroneous state from a 2Gbyte data buffer.
This marks a breakthrough in on-chip debugging, allowing for the first time an on-chip trace port in a nonbondout version of all AVR32 microcontrollers.
The AVR One! expands Atmel's line-up of on-chip debug adapters, which already consists of the very popular JTAGICE mkII and the low cost AVR Dragon introduced last year.
Customers can now choose the tool that best fits their needs and budgets.
To support the new AVR One! on-chip debugger, Atmel has released version 2.0 of its popular AVR32 Studio project manager and debugger front-end.
In addition to full support for the new AVR One! on-chip debug adapter, the new version of AVR32 Studio has even better integration of the AVR32 Software Framework, Atmel's large library of optimised device drivers, DSP math functions and communication stacks.
AVR32 Studio and AVR32 Software Framework is available free of charge from Atmel's website.
