FAQ

What is the maximum operating frequency of the MK22FX512VMD12 core?

The MK22FX512VMD12 features an ARM Cortex-M4 core with floating-point unit rated for up to 120 MHz operation. This frequency is achievable when the Phase-Locked Loop (PLL) is configured in PEE mode with a 3–32 MHz crystal input. At 120 MHz, the device delivers 1.25 Dhrystone MIPS per MHz, enabling efficient execution of real-time control and signal processing tasks without external acceleration.

Does the MK22FX512VMD12 support USB device charging detection?

Yes, the MK22FX512VMD12 includes a dedicated USB Device Charger Detect (DCD) module compliant with USB Battery Charging Specification 1.2. This allows the MK22FX512VMD12 to automatically identify standard downstream ports (SDP), charging downstream ports (CDP), and dedicated chargers (DCP) - enabling intelligent power management decisions such as adjusting charge current or entering low-power modes when connected to a wall adapter.

What low-power modes are available on the MK22FX512VMD12, and what is the lowest current draw?

The MK22FX512VMD12 supports multiple low-power modes including VLPR, VLPS, LLS, and VLLS0–VLLS3. The lowest static current is achieved in VLLS0 mode with POR detect disabled: 268 nA at 3.0 V and –40 to 25°C, with full register and RAM retention and 5 μs wake-up time. This makes MK22FX512VMD12 suitable for battery-backed or energy-harvesting applications requiring multi-year standby life.

Is the MK22FX512VMD12 pin-compatible with other K22 family members in the same package?

Yes, the MK22FX512VMD12 is pin-compatible with other 144-pin MAPBGA K22F variants including MK22FN1M0VMD12 and MK22FX512VLQ12 (LQFP variant has different pinout). All share identical signal mapping, power/ground pin locations, and peripheral pin assignments per K22P144M120SF5 datasheet Rev 4 - enabling drop-in replacement for flash capacity or package form factor changes without PCB redesign.

What analog peripherals are integrated into the MK22FX512VMD12?

The MK22FX512VMD12 integrates two independent 16-bit SAR analog-to-digital converters (ADCs), two 12-bit digital-to-analog converters (DACs), three analog comparators (CMP), and a precision voltage reference module. These peripherals support simultaneous sampling, programmable gain amplification, and windowed comparison - enabling high-fidelity sensor conditioning, closed-loop control, and analog monitoring directly on the MK22FX512VMD12 without external signal chain components.
