Kinetis KL1x Microcontrollers

NXP Semiconductors Kinetis KL1x Microcontrollers, based on the Arm® Cortex®-M0+ core, combine ultra-low-power performance with a rich suite of analog, communication, timing, and control peripherals. Kinetis KL1x MCUs start from 32KB of flash in a small 3.5mm x 3.5mm XFBGA-32 package, extending up to 256KB in an LQFP-80 package. The NXP KL1x MCU family is compatible with the Cortex M4-based Kinetis K10 MCU family, offering a migration path to higher performance and feature integration.
