Kinetis KL3x Microcontrollers

NXP Semiconductors Kinetis KL3x Microcontrollers, based on the Arm® Cortex®-M0+ core combine ultra-low power performance with a rich suite of analog, communication, timing, and control peripherals, including a low-power segment LCD controller with support for up to 376 segments. NXP Kinetis KL3x start from 32KB of flash in a QFN-48 package, extending up to 256KB in a MBGA-121 package. The Kinetis KL3x MCUs are compatible with the ARM Cortex-M4- based Kinetis K30 MCU family, offering a migration path to higher performance and feature integration.
