FRDM-K22F
Overview
The FRDM-K22F is an ultra-low-cost development platform for the Kinetis K22 microcontrollers, based on the ARM Cortex-M4 core with a floating-point unit (FPU). The board features a 120 MHz MK22FN512VLH12 MCU with 512 KB Flash and 128 KB RAM, and it is designed for rapid prototyping with a form factor compatible with the Arduino R3 pin layout.
Why Choose This Part
The platform includes an on-board OpenSDAv2 serial and debug adapter, eliminating the need for an external programmer. It provides 64 GPIO pins, 20 PWM channels, and dual I2C/SPI interfaces, making it highly extensible for complex peripheral interfacing.
Applications
Key Specifications
Getting Started
To begin development, connect the board via USB to utilize the OpenSDAv2 interface for drag-and-drop programming or CMSIS-DAP debugging. It is fully supported by MCUXpresso SDK, IAR Embedded Workbench, and Keil MDK, and is compatible with the ARM mbed online ecosystem.
