The NXP MKL25Z32VFT4 is a 32-bit ARM Cortex-M0+ MCU from the Kinetis KL2 series, clocked at 48 MHz with 32 KB Flash and 4 KB RAM. The 48-QFN package with exposed pad sits on a 7×7 mm footprint, rated for -40°C to 105°C operation. This part targets sensor-fusion nodes, USB data-loggers, and compact control panels where the USB OTG port serves both firmware updates and peripheral attachment without a separate USB host chip.
