The NXP MKL25Z128VFT4 is a 32-bit ARM Cortex-M0+ MCU from the Kinetis KL2 series, clocked at 48 MHz with 128 KB Flash and 16 KB RAM. The operating range spans 1.71 V to 3.6 V and -40 °C to 105 °C, so it fits industrial enclosures, outdoor telecom cabinets, and under-hood automotive auxiliary modules.
At 48 MHz the Cortex-M0+ delivers enough throughput for USB full-speed, a 16-bit ADC sample stream, and a control loop without stalling.
The MKL25Z256VFT4 (256 KB Flash variant) is pin-compatible within the same Kinetis KL2 family, sharing the same 48-QFN footprint and peripheral set. No board layout change is needed for a density upgrade.
The part is RoHS-compliant per NXP's standard material declaration. A full RoHS/REACH certificate and the datasheet are available on request.
