features a 64-pin, 256KB SAM D20 device along with a programmer/debugger and hardware to evaluate both the processor and the peripherals. The Xplained PRO kit also comes pre-loaded with software that can easily be re-programmed, debugged and prototyped without any additional tools. Samples of 128 kB 32-pin, and 256 kB 48-and 64 pin products are available in QFN and QFP packages. Pricing starts at $1.02 (1000) for the 16KB 32-pin QFN package.


Debug support from Segger

Segger is offering debug support at launch for Atmel’s SAM D20, with the J-Link family of debug probes. The Cortex-M0+ core has 4 hardware breakpoints which can be used in internal flash memory. The J-Link family can enhance the debug experience for the developer with the unlimited number of Flash Breakpoints. This feature, available in J-Link PLUS, J-Link ULTRA+, J-Link PRO and J-Trace, allows the developer to set an unlimited number of breakpoints in internal and external flash memory.
