The FRDM-KL46Z is an ultra-low-cost development platform enabled by the Kinetis L series KL4x MCU family built on the ARM Cortex-M0+ processor. Features include easy access to MCU I/O, battery-ready, low-power operation, a standard-based form factor with expansion board options and a built-in debug interface for flash programming and run-control. The FRDM-KL46Z is supported by a range of Freescale and third-party development software.

The Kinetis KL4x family is pin, peripheral and software compatible with all other Kinetis L series families and combines a full-speed USB 2.0 On-The-Go(OTG) controller with integrated low-voltage regulator and a flexible, low-power segment LCD controller with support for up to 376 segments.  These features make the KL4x family well suited to display-based applications like electronic scales, thermostats, flow meters and smart meters.
