The MK22FN512CAP12R: 32-bit ARM Cortex-M4 MCU from the Kinetis K20 series, clocked at 120 MHz with 512 KB Flash and 128 KB RAM. Connectivity includes USB OTG (dual-role host/device), I2C, SPI, UART/USART, and IrDA — a full set for bridging sensors, displays, or a serial console. The 52 GPIOs in the 80-WLCSP package are enough for a keypad-plus-LCD interface or a distributed I/O node, but the fine-pitch WLCSP (4.13×3.56 mm) demands careful PCB layout and underfill for mechanical reliability in high-vibration environments.
