FAQ

What is the maximum operating frequency of the MK40DN512VLK10?

The MK40DN512VLK10 operates at a maximum CPU frequency of 100 MHz, enabled by its ARM Cortex-M4 core with DSP extensions. This frequency is supported across the full -40°C to +105°C ambient temperature range and 1.71–3.6 V supply voltage, delivering 1.25 Dhrystone MIPS per MHz. The MK40DN512VLK10 achieves this performance using its Multi-Purpose Clock Generator (MCG) in PLL mode with external crystal input.

Does the MK40DN512VLK10 include a hardware floating-point unit (FPU)?

No, the MK40DN512VLK10 does not include a hardware FPU. Its part number suffix "D" indicates Cortex-M4 with DSP instructions only; the "F" suffix (e.g., MK40FN512VLK10) denotes inclusion of the single-precision FPU. The MK40DN512VLK10 supports efficient fixed-point and integer DSP operations (e.g., MAC, saturating arithmetic) but relies on software libraries for floating-point computation.

What package type and pin count does the MK40DN512VLK10 use?

The MK40DN512VLK10 uses an 80-pin LQFP package (12 mm × 12 mm), identified by the "LK" field in its part number. This package provides full access to all peripherals including USB DP/DM, CAN TX/RX, dual ADC inputs, LCD segment/backplane lines, and 64 general-purpose I/O pins - optimized for prototyping and production with standard reflow profiles and MSL3 handling.

Can the MK40DN512VLK10 operate from a single 3.3 V supply?

Yes, the MK40DN512VLK10 operates reliably from a single 3.3 V supply, which falls within its specified 1.71–3.6 V VDD range. At 3.3 V, it supports full 100 MHz operation, all peripheral functions (including USB transceiver and analog modules), and achieves typical run-mode current of 38 mA (all clocks disabled) or 64 mA (all clocks enabled). VDDA must be tied to the same 3.3 V rail with proper decoupling.

What is the lowest power consumption mode supported by the MK40DN512VLK10?

The MK40DN512VLK10 achieves its lowest active power state in Very-Low-Leakage Stop Mode 1 (VLLS1), with typical current consumption of 2.1 µA at -40°C to +25°C and 3.0 V supply. In this mode, the RTC remains active, RAM is retained, and the device can wake via GPIO, RTC alarm, or low-power timer - enabling multi-year battery life in intermittent-sensing applications such as wireless sensor nodes or portable medical devices.
