Descrição
Freescale FRDM-K22F Freedom Board
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
