This port is for the FRDM-K28F development board that features the MK28FN2M0VMI15 MCU. The features of the FRDM-K28F board are:
o Kinetis MK28FN2M0VMI15 MCU (ARM Cortex-M4 at150 MHz, 1 MB SRAM, 2 MB flash,
HS and FS USB, 169 MAPBGA package).
o Kinetis K20 MCU (K20DX128VFM5) based OpenSDA circuit.
o Dual-role high-speed and full-speed USB interface with the micro-B USB
connector via the high-speed switch.
o One 256 Mbit (32 MB) on-board QuadSPI memory at 1.8 V.
o One 128 Mbit (16 MB) on-board mobile SDRAM memory at 3.3 V.
o Multiple independent voltage domains: VDD_CORE, VDD, VBAT, and VDDIO_E.
o FlexIO socket which enables you to connect an optional TFT Proto 5"
CAPACITIVE from MikroElektronika (5" display board with capacitive touch).
o Easy access to the MCU input/output through Arduino R3-compatible I/O
connectors to connect external add-on boards.
o Flexible power supply option—OpenSDA v2.2 USB, Kinetis K28 USB, or an
external source.
o FXOS8700CQ—6-axis sensor with accelerometer and magnetometer.
o RGB LED.
o Two mechanical push-buttons for user input and one for the reset.
o Programmable OpenSDA v2.2 debug circuit supporting the DAP-Link interface
software which provides:
- Mass-Storage Device (MSD) flash programming interface.
- CMSIS-DAP debug interface over a driverless USB HID connection providing
run-control debugging and compatibility with the IDE tools.
- Virtual serial port interface.
- Open-source CMSIS-DAP software project.
