FRDM-KL46Z 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
KL46Z hardware, FRDM-KL46Z, is a simple, yet sophisticated design featuring a Kinetis L series microcontroller,
built on the ARM® Cortex™-M0+ core.
FRDM-KL46Z can be used to evaluate the KL46, KL36, KL26 and KL16 Kinetis L series devices. It features a
MKL46Z256VLL4, this device boasting a max operating frequency of 48MHz, 256KB of flash, 32KB RAM, a full-
speed USB controller, segment LCD controller, and loads of analog and digital peripherals. The FRDM-KL46Z
hardware is form-factor compatible with the Arduino™ R3 pin layout, providing a broad range of expansion
board options. The on-board interfaces includes a 4 digit segment LCD, a 3-axis digital accelerometer,
magnetometer, capacitive touch slider, and ambient light sensor.
The FRDM-KL46Z 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.
