FAQ

What is the maximum operating frequency and core type of the MK20FN1M0VLQ12R?

The MK20FN1M0VLQ12R features an ARM Cortex-M4F core with integrated single-precision floating-point unit, rated for operation up to 120 MHz across its full -40°C to +105°C temperature range. This frequency is achieved using the on-chip PLL driven by the 3–32 MHz external crystal oscillator, and is validated under worst-case voltage (1.71 V) and temperature conditions per the K20P121M100SF2 datasheet Rev. 7.

Does the MK20FN1M0VLQ12R support hardware floating-point operations?

Yes, the MK20FN1M0VLQ12R includes a full IEEE 754-compliant single-precision floating-point unit (FPU) integrated into its ARM Cortex-M4F core. This enables hardware-accelerated trigonometric, exponential, and division operations-critical for real-time motor control algorithms and sensor fusion in the MK20FN1M0VLQ12R's target applications.

What analog peripherals are integrated into the MK20FN1M0VLQ12R?

The MK20FN1M0VLQ12R integrates two independent 16-bit SAR ADCs with programmable gain amplifiers (up to x64), two 12-bit DACs, three analog comparators each with a built-in 6-bit DAC and programmable reference, and a precision voltage reference module. All analog blocks share dedicated VDDA/VSSA rails and operate across the full 1.71–3.6 V supply range specified for the MK20FN1M0VLQ12R.

What is the package type and pin count of the MK20FN1M0VLQ12R?

The MK20FN1M0VLQ12R uses a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch) with an exposed thermal pad. This package is explicitly identified by the "LQ" field in the part number per the K20 Sub-Family Data Sheet format definition, and supports standard surface-mount assembly, thermal dissipation for sustained 120 MHz operation, and mechanical robustness in industrial environments.

How does the MK20FN1M0VLQ12R handle low-power operation in industrial applications?

The MK20FN1M0VLQ12R offers seven low-power modes-including VLLS1–VLLS3-with measured stop-mode currents as low as 2.1 µA at -40°C to 25°C. Its low-leakage wakeup unit, programmable delay block, and hardware RTC enable rapid wake-up (<100 µs) from deep sleep on GPIO, comparator, or RTC alarms-making the MK20FN1M0VLQ12R ideal for battery-backed industrial sensors and energy-conscious control systems.
