FAQ

What is the maximum operating frequency of the MK12DN512VLH5?

The MK12DN512VLH5 features an ARM Cortex-M4 core rated for up to 50 MHz operation. This frequency is supported across the full –40°C to 105°C ambient temperature range and 1.71–3.6 V supply voltage, with system and bus clocks synchronized to the core clock. The device achieves 1.25 Dhrystone MIPS per MHz, enabling efficient execution of DSP-intensive firmware.

Does the MK12DN512VLH5 include FlexNVM or FlexRAM memory?

No, the MK12DN512VLH5 does not include FlexNVM or FlexRAM. As indicated by the 'N' in its part number (MK12DN512VLH5), it contains 512 KB of program flash only, with no emulated EEPROM or user-configurable NVM partitioning. It includes 64 KB of SRAM and 4 KB of dedicated FlexRAM is absent - this configuration simplifies memory management for applications not requiring field-upgradable nonvolatile data storage.

What analog peripherals are integrated into the MK12DN512VLH5?

The MK12DN512VLH5 integrates a 16-bit SAR ADC with up to 16 input channels, a 12-bit DAC, two analog comparators each with a 6-bit DAC and programmable reference, and a precision voltage reference module. These peripherals support high-accuracy sensor interfacing, closed-loop analog control, and calibration functions without external components - all operating within the same 1.71–3.6 V supply range as the digital core.

Which communication interfaces does the MK12DN512VLH5 support?

The MK12DN512VLH5 supports USB Device (with Charger Detect), four UART modules, two I²C modules, multiple SPI interfaces (including DSPI), and an I²S audio interface. It also includes a serial programming interface (EzPort) for flash programming. These interfaces enable robust connectivity for industrial HMI, sensor networks, audio edge processing, and USB peripheral applications - all with independent clock domains and DMA support.

What low-power modes are available on the MK12DN512VLH5?

The MK12DN512VLH5 offers six low-power modes: RUN, WAIT, STOP, VLPR, VLPW, and VLPS, plus four Very-Low-Leakage Stop (VLLS) modes. VLLS0 achieves as low as 0.543 µA (at –40°C to 25°C) with POR detect enabled, while VLPS draws 7.33 µA under the same conditions. Wakeup sources include GPIO, RTC alarm, and low-power timer - making MK12DN512VLH5 suitable for energy-constrained battery-operated systems.
