Kinetis® KL2x Microcontrollers

NXP Semiconductors Kinetis® KL2x Microcontrollers are pin, software, and tool compatible with all other Kinetis L MCU families and add a full-speed USB 2.0 On-The-Go (OTG) controller with an integrated low-voltage regulator. The Kinetis KL2x MCU family is also compatible with the Kinetis K20 MCU family (based on the Arm® Cortex®-M4 processor), providing a migration path to higher performance and feature integration. Devices start from 32KB of flash in a small-footprint 5x5mm 32 QFN package extending up to 512KB in a 121 MBGA package. Each combines ultra-low-power performance with a rich suite of analog, communication, timing, and control peripherals.
