Overview

The Kinetis KL1x MCU family is pin, software and tool compatible with all other

Kinetis L families, and provides additional memory, communications and analog

peripheral options beyond those offered on the KL0x family. The Kinetis KL1x MCU

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 80 LQFP package. Each family member

combines ultra-low-power performance with a rich suite of analog, communication,

timing and control peripherals.
