FRDM-K28F Freedom Development Board User Guide
Hardware user guide for the FRDM-K28F development platform featuring the Kinetis MK28FN2M0VMI15 MCU, Arduino R3 compatibility, and onboard OpenSDA v2.2 debug interface.
Overview
The FRDM-K28F is a hardware development platform for evaluating NXP Kinetis K27 and K28 MCUs. Centered on the MK28FN2M0VMI15 ARM Cortex-M4 MCU, the board operates up to 150 MHz and includes 2 MB flash and 1 MB RAM. Key features include high-speed and full-speed USB controllers, a 256 Mbit QuadSPI serial flash, and 128 Mbit of mobile SDRAM. The board is form-factor compatible with Arduino R3 headers and includes a FlexIO socket for external display modules. Integrated peripherals consist of an FXOS8700CQ 6-axis sensor, an SD card interface, and a visible light sensor. Debugging is facilitated by the onboard OpenSDA v2.2 circuit based on the Kinetis K20 MCU.
Use Cases
- IoT device prototyping
- Kinetis K27 and K28 MCU evaluation
- USB High-Speed application development
