FAQ

What is the maximum operating frequency of the MK20FX512VMD12?

The MK20FX512VMD12 operates at a maximum CPU frequency of 120 MHz, achieved using the internal MCG clock generator in FEE mode. This frequency enables sub-microsecond interrupt response and high-resolution PWM generation required in servo and power conversion systems. The MK20FX512VMD12 maintains timing compliance across its full -40°C to 105°C operating range when supplied within the 1.71–3.6 V voltage window.

Does the MK20FX512VMD12 include a hardware floating-point unit (FPU)?

Yes, the MK20FX512VMD12 integrates a single-precision IEEE 754 compliant FPU as part of its ARM Cortex-M4 core. This allows efficient execution of trigonometric, exponential, and filtering operations without software emulation overhead. The FPU significantly accelerates motor control algorithms and sensor fusion routines in the MK20FX512VMD12, distinguishing it from non-FPU variants like the K20DN series.

What package type and pin count does the MK20FX512VMD12 use?

The MK20FX512VMD12 uses a 121-pin MAPBGA package (8 mm × 8 mm, 0.5 mm pitch), designated by the 'MC' package code in its part number. This high-density package supports full peripheral routing including dual CAN, USB, multiple ADC channels, and FlexBus expansion - making it suitable for compact industrial control modules where board space is constrained.

How much flash and RAM memory does the MK20FX512VMD12 provide?

The MK20FX512VMD12 provides 512 KB of on-chip program flash memory and 128 KB of general-purpose SRAM. It also includes 4 KB of FlexRAM and supports FlexNVM configuration for EEPROM-like wear leveling. This memory configuration allows complex real-time firmware, dual-bank OTA updates, and large sensor data buffers - all within the MK20FX512VMD12's integrated architecture.

Is the MK20FX512VMD12 qualified for automotive or industrial temperature ranges?

Yes, the MK20FX512VMD12 is rated for operation from -40°C to +105°C (indicated by the 'V' suffix in its part number), meeting industrial and under-hood automotive requirements. It undergoes extended temperature qualification per AEC-Q100 stress test standards and supports robust operation in factory automation, motor drives, and vehicle body electronics where thermal stability is critical for MK20FX512VMD12-based systems.
