    Design freedom in the palm of your hand. The FRDM-KL46Z allows you to quickly prototype your next microcontroller application by taking advantage of the features of the NXP Freedom platform. The FRDM-KL46Z is a small but feature-rich evaluation board featuring a low-power Kinetis L series microcontroller with segment LCD and USB support, built on the ARM® Cortex™-M0 core.

    The FRDM-KL46Z development board is a superset of the ground breaking FRDM-KL25Z board, and adds even more features and memory. The MCU on board is a MKL46Z256VLL4, which boasts 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.

    With the ARM Cortex M0 based Kinetis L family, it is now possible to leverage 32-bit capabilities and the scalability needed to expand future product lines, all at 8- and 16-bit price and power consumption levels. The and can be used to evaluate the KL46, KL36, KL26 and KL16 Kinetis L series devices. It’s also upward compatible with the more powerful Cortex-M4 based Kinetis K40 family of devices, providing an easy upgrade path to the next level of performance.

    Freedom To Do More

    The FRDM-KL46Z on-board interfaces include a 4 digit segment LCD, a 3-axis digital accelerometer, magnetometer, capacitive touch slider, and ambient light sensor. The KL46 device is also supported by the major ARM toolchains like Keil, IAR, CodeWarrior, Red Suite, and more, and has complimentary RTOS and USB stack support with MQX-Lite and Processor Expert. Plus the FRDM-KL46Z is form-factor compatible with the Arduino™ R3 pin layout, meaning immediate access to thousands of community created shields and endless possibilities.

    The FRDM-KL46Z also features the NXP standard embedded serial and debug adapter, known as OpenSDA, built right into the board. This circuit offers several options for serial communications, flash programming and run-control debugging all over a simple USB cable. Ditch the expensive debugger and complicated flashing procedure: just drag, drop, and run!

    Let your design ideas free by prototyping them with a powerful microcontroller with a low-power core, all on a flexible low-cost platform and with a large ecosystem of compatible hardware and software. It’s the freedom to do more.

    Key Applications: Portable instrumentation, Industrial automation, Small appliances, Portable media players, etc.
