Datasheet

Overview
The Kinetis KL2x MCU family is pin, software and tool compatible with all other
Kinetis L families, and adds a Full-Speed USB 2.0 On-The-Go controller with an
integrated low-voltage regulator. The Kinetis KL2x MCU family is also compatible
with the Kinetis K20 family of MCUs built on the ARM
®
Cortex
TM
-M4 core, providing
a migration path to higher performance and feature integration. Devices start from
32 KB of flash in a small-footprint 5 x 5 mm 32 QFN package, extending up to
256 KB in a 100 LQFP/121 MBGA package. Each family member combines
ultra-low-power performance with a with a rich suite of analog, communication,
timing and control peripherals.
