There are also many software development tool options available to the user.  Choices include Kinetis 
Design Studio (KDS), IAR Embedded Workbench, Keil MDK featuring the µVision IDE, etc. 

All of these features combine to give users the freedom needed to rapidly prototype many embedded 
designs: a powerful microcontroller built on a very low-power core and SoC platform, easy-access to I/O 
with a large ecosystem of compatible hardware, a flexible programming and debug interface, and a large 
ecosystem of software development environments.
