Freescale Freedom Development Platform: Rapidly prototype ARM®︎ Cortex™︎-M4 and Cortex™︎M0+ processors

The Freescale Freedom development platform is a small, low-power, cost-effective evaluation and development system for quick application prototyping and demonstration of the Freescale Kinetis ARM Cortex-M4 and CortexM0+ MCU families.

Each platform offers an easy-to-use mass-storage device mode flash programmer, virtual serial port, and classic programming and run-control capabilities.

It’s easy to get started. Simply choose your preferred Freescale Freedom development hardware, select compatible software, connect with the community, and go!

Features

• Cost effective (starting at $12.95)

• Small size (approximately 3.25” x 2”), fits within a mint tin

• Arduino footprint-compatible with support for a rich-set of third-party expansion boards (“shields”)

• Easy access to the MCU I/O pins

• Integrated open-standard serial and debug adapter (OpenSDA) with support for several industry standard debug interfaces

Software Enablement and Support

• Rich ARM ecosystem includes Keil MDK-ARM, IAR EWARM, SEGGER, CodeWarrior for MCU 10.5, mbed (for FRDM-KL25Z, FRDM-KL46Z, and FRDM-KL05Z) and more

• Freescale MQX Lite RTOS: Very light MQX kernel for resource-limited MCUs that allows applications to run with less than 4 KB RAM

• Processor Expert software and embedded components

• FRDM-KL25Z, FRDM-KL46Z, and FRDM-KL05Z are mbed-enabled through the built-in USB flash programming interface (OpenSDA). Simply plug it in, drop on an “mbed interface” program binary, and it’s up and running

OpenSDA: Open-Standard Serial And Debug Adapter

The integrated debug circuit, OpenSDA, bridges serial and debug communications between a USB host and an embedded target processor. OpenSDA features a mass storage device bootloader, which provides a quick and easy mechanism for loading different OpenSDA applications such as flash programmers, run-control debug interfaces, serial-to-USB converters and more including:

• Freescale mass storage device flash programming interface eliminates tool installation for quick evaluation of demonstration applications

• P&E Multilink interface provides run-control debugging and compatibility with IDE tools

• SEGGER OpenSDA firmware makes OpenSDA compatible to J-Link Lite

• mbed interface application provides connection to mbed online tools and supports a virtual serial port, CMSIS-DAP, and a mass-storage programming interface

• CMSIS-DAP interface (stand alone): New ARM standard for embedded debug interfaces

Freedom Board Options

FRDM-KL02Z is the recommended development board if you are migrating from the 8-bit MCU world, and you are looking for the easiest tool to evaluate the Freescale Kinetis-L MCU family based on the new ARM CortexM0+ core with the ability for Low-Power applications.

FRDM-KL05Z improves on the FRDM-KL02Z performance thanks to the KL05 MCU on board, which adds DMA, a DAC, and a hardware touch sensor controller (TSI).

FRDM-KL25Z is the right choice to evaluate Kinetis-L1x and L2x MCUs, if you feel comfortable with C-programming and the use of a RTOS with 32-bit MCUs, or if you just need 16-bit ADC resolution and a USB OTG Full-Speed Controller onboard.

FRDM-KL26Z is an improvement to the KL25Z, and adds I2S, a 16-bit (vs 8-bit) SPI, an additional GPIO port with interrupt capability, and more. The board also features the new FXOS8700CQFXOS8700CQ sensor device, which is a combined accelerometer and magnetometer.

FRDM-KL46Z has the Freescale Kinetis KL46, an ARM CortexM0+ MCU, which extend the memory size of the FRDM-KL25Z to 256KB of Flash and 32KB of RAM. It also adds a Segment LCD controller and an I2S interface to connect an Audio Codec. Concerning the external components on the board, a 3D magnetormeter and two user push buttons are now available. It is the right choice to evaluate Freescale Kinetis-L3x and L4x MCU families, or if your application require more memory (Flash, RAM) or LCD-Segment and USB OTG Full-Speed controllers.

FRDM-KE02Z features the entry-level KE02 MCU, from the new Freescale Kinetis-E family, the first ARM CortexM0+ series for 5V tolerant EMC/ESD performance. Even if you still choose to use a 3.3V supply, the KE02 offers three Flextimers, three SCI serial interfaces (LIN capable), 256B of true EEPROM, and enhanced GPIOs (eight high-drive and two true open-drain). This board is recommended if you are looking for evaluating a low-cost integrated 32-bit MCU for your basic motor-control application, or if you just require EMC/ESD robustness and 5V-capabilities.

FRDM-K20D50M has increased performance compared to the FRDM-KL25Z thanks to the Kinetis-K20, an ARM Cortex-M4 MCU with DSP instructions
