Part Number:FRDM-K22F

The FRDM-K22F is the second Freedom board featuring a Kinetis K Next-Generation MCU (after the FRDM-K64F).

It is targeting USB applications with a high-level of integration thanks to the crystal-less feature of its new USB controller (48MHz external crystal saved on the BOM cost) and the lower-power capabilities of this new generation of ARM Cortex-M4 MCUs. The FRDM-K22F is based on a Kinetis MK22FN512VLH12 device featuring an ARM Cortex-M4 core @120MHz with Floating Point Unit and embeds 512KB Flash, 128KB RAM in a LQFP64 Package.

The new OpenSDA v2 (same as FRDM-K64F) supports CMSIS-DAP interface software which provides: Mass Storage Device (MSD flash programming, CMSIS-DAP debug over USB and a virtual serial port.

The FRDM-K22F comes with demo applications including:

  • Bubble level –Single axis level using the red and green LEDs to indicate when the board is unlevel.
  • eCompass demo –Compass using the combined magnetometer and accelerometer to indicate the heading of board in reference to magnetic north.
  • USB CDC demo –Second serial terminal
  • Metal Detector demo –Metal detector demo that indicates the direction and distance to a foreign metal object using the variable LED brightness as the indicator.
  • Stopwatch demo –Uses the real-time counter (RTC) to implement a stopwatch with 1/100thof a second precision.
  • Air mouse demo –USB mouse using the accelerometer to determine where/how to move the cursor

  Key Applications:

  • Barcode scanners
  • Gaming accessories
  • Health and wellness monitors
  • Home and building automation
  • Industrial/commercial sensor nodes
  • IoT data concentrators
  • Multi-functional printers
  • Sports and activity wearables

FAQs

Can you build a complete e-compass using this board ?

This board has 6-axis digital accelerometer and magnetometer (FXOS8700CQ ) to create full eCompass capabilities.

What is the supprted JTAG emulator for this freedom board ?

Part Number # TMDSEMU100V2U-20T(64R0682) is 20 pin JTG Emulator and TMDSEMU100V2U-14T (64R0681) USB 14 pin JTAG emulator

What is OpenSDAv2? Does this board support it?

FRDM-K22F board supports OpenSDAv2. OpenSDAv2 is the Freescale open-source hardware embedded serial and debug adapter running an open-source bootloader. This circuit offers several options for serial communication, flash programming, and run-control debugging.

What is the unique features of this board ?

This board is having Crystal-less USB (Host/Device) which is different than other freedom boards.

Does this board support mbed based development ?

The FRDM-K22F board is also enabled with the ARM® mbed™ development platform, which means you can quickly get started designing using web-based tools. No downloads or installations.

What are the available debug interfaces present on this board?

There are two debug interfaces on the FRDM-K22F: an onboard OpenSDAv2 circuit (J5) and a K22F direct SWD connection via a 10-pin header (J11). To use an external debugger, such as J-Link on
J11, you may need to disconnect the OpenSDAv2 SWD circuit from the K22F by removing jumpers J13 and J10.
