48 MHz Cortex-M0+ with 128 KB Flash — fit for sensor and control loops
The MKL16Z128VFM4R: The -40 to 105 °C temperature grade qualifies it for outdoor telecom cabinets, motor-drive enclosures, and engine-bay-adjacent electronics where ambient heat cycles exceed standard commercial range. Twenty-eight I/O in a 32-HVQFN package with wettable flank pads — the wettable flank is a production-line advantage: it allows automated optical inspection (AOI) of solder joints, which matters for high-reliability builds and automotive-tier quality gates.
