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
