Kinetis^® KL2x-72/96 MHz, USB Ultra-Low-Power Microcontrollers (MCUs) based on Arm^® Cortex^&#

The Kinetis® KL2x is an ultra-low-power MCU family that adds a full-speed USB 2.0 On-the-Go (OTG) controller or a full-speed crystal-less USB 2.0 device controller in addition to the Kinetis KL1x series.

The Kinetis KL2x MCU family is compatible with Kinetis K20 MCUs (based on Arm® Cortex®-M4), and with all other Kinetis KL1x, KL2x, KL3x, and KL4x series MCUs, providing a migration path to lower and higher performance and feature integration.
