The 48-VFQFN exposed pad package keeps thermal transfer direct to the board for the 1.71 V to 3.6 V supply range. ## Industrial temperature grade — what it means for deployment The internal oscillator and brown-out detect keep it running through supply dips — no external supervisor needed for basic reset. ## 48 MHz — enough for control, not for DSP 48 MHz is a solid mid-range speed for the Cortex-M0+ core. It handles PID loops, Modbus polling, and 12-bit ADC reads at 15 channels without breaking a sweat. If you need floating-point or FFT-heavy work, step up to a Cortex-M4 part — this one is about power efficiency and deterministic I/O.","metaTitle":"NXP MKL14Z64VFT4R Kinetis KL1 MCU, 48MHz, 64KB Flash, 8KB RAM","metaDescription":"NXP MKL14Z64VFT4R ARM Cortex-M0+ MCU, 48MHz, 64KB Flash, 8KB RAM, 40 I/O, 15-ch 12-bit ADC, -40°C to 105°C, 1.71V-3.6V, 48-QFN.
