1 Overview

The Freescale Freedom development platform is a set of software and hardware tools for evaluation
and development. It is ideal for rapid prototyping of microcontroller-based applications. The Freescale
Freedom KL05Z hardware, FRDM-KL05Z, is a simple, yet sophisticated design featuring a Kinetis L series
microcontroller, the industry’s first microcontroller built on the ARM® Cortex™-M0+ core.

FRDM-KL05Z can be used to evaluate the KL04 and KL05 Kinetis L series devices. It features a
MKL05Z32VFM4, a KL0 family device boasting a max operating frequency of 48MHz, 32KB of flash, and
a multitude of analog and digital peripherals. The FRDM-KL05Z hardware is form-factor compatible
with the Arduino™ R3 pin layout, providing a broad range of expansion board options. The on-board
interfaces include an RGB LED, a 3-axis digital accelerometer, and a capacitive touch slider.

The FRDM-KL05Z also features the Freescale open standard embedded serial and debug adapter
known as OpenSDA. This circuit offers several options for serial communications, flash programming
and run-control debugging.
