FAQ

What is the maximum operating frequency of the MK30DX64VLK7R?

The MK30DX64VLK7R operates at a maximum CPU frequency of 72 MHz. This is defined by its silicon revision and speed grade ('7' in the part number suffix). At this frequency, the ARM Cortex-M4 core delivers 1.25 Dhrystone MIPS per MHz, enabling deterministic execution of motor control loops and digital signal processing routines. The MK30DX64VLK7R achieves this using the MCG's FEE mode with appropriate PLL configuration and stable 3–32 MHz crystal input.

Does the MK30DX64VLK7R support hardware floating-point operations?

No, the MK30DX64VLK7R does not include a hardware floating-point unit (FPU). It is based on the ARM Cortex-M4 core *without* FPU (indicated by 'D' in the part number format, not 'F'). All floating-point calculations must be performed in software using CMSIS-DSP libraries. For applications requiring hardware FPU acceleration, consider alternatives like K22FN512VLH12, which uses the Cortex-M4F core and is pin-compatible in the same 80-LQFP package.

What are the supported low-power modes and their typical current consumption for MK30DX64VLK7R?

The MK30DX64VLK7R supports seven low-power modes: RUN, WAIT, VLPR, STOP, VLPS, LLS, and VLLS (1–3). At 3.0 V and –40°C to 25°C ambient, typical currents are: VLPS = 0.435 mA, LLS = 19.9 μA, VLLS1 = 9 μA, VLLS2 = 5.4 μA, and VLLS3 = 23 μA. These values assume RTC disabled and minimal wake-up sources enabled. The MK30DX64VLK7R achieves these figures using clock gating, peripheral isolation, and optimized SRAM retention strategies.

Can the MK30DX64VLK7R drive an LCD directly without external components?

Yes, the MK30DX64VLK7R integrates a segment LCD controller supporting up to 40 frontplanes and 8 backplanes (or 44 frontplanes and 4 backplanes depending on package). It provides internal charge pump and bias generation, eliminating external voltage boosters for common 3.3 V LCD glass. The MK30DX64VLK7R also supports static, 2-, 3-, or 4-mux configurations and software-controlled contrast adjustment - making it suitable for industrial HMIs with segmented displays.

What is the function of the Programmable Delay Block (PDB) in MK30DX64VLK7R?

The Programmable Delay Block (PDB) in the MK30DX64VLK7R provides precise, hardware-synchronized triggering of ADC conversions, DAC updates, and PWM reload events. It supports configurable pre-trigger and post-trigger delays, multiple channels, and chaining between modules. In motor control applications, the MK30DX64VLK7R uses PDB to align current-sampling windows with PWM center-aligned edges - critical for accurate field-oriented control without software jitter or interrupt latency.
