The FRDM-KL25Z is an ultra-low-cost development platform enabled by Kinetis L Series KL1x and KL2x MCUs families built on ARM® Cortex™-M0+ processor. Features include easy access to MCU I/O, battery-ready, low-power operation, a standard-based form factor with expansion board options and a built-in debug interface for flash programming and run-control. The FRDM-KL25Z is supported by a range of Freescale and third-party development software.
ARM offers the Keil Microcontroller Development Kit (MDK-ARM) for ARM powered microcontrollers. It features the industry-standard compiler from ARM, the Keil µVision IDE, and sophisticated debug and data trace capabilities. MDK-ARM offers tailored support for all Cortex-M processor-based devices, and is the recommended solution for students working with standard ARM-based MCU devices. We suggest that students and universities download the free evaluation version of the tools, which offers all the features of the standard version, but with a 32 KByte object code/data limit.
