FAQ

What is the maximum operating frequency of the MK22FN1M0AVLK12 core?

The MK22FN1M0AVLK12 features an ARM Cortex-M4 core with floating-point unit rated for up to 120 MHz operation. This frequency is achievable under specified conditions: VDD = 1.71–3.6 V, ambient temperature –40°C to 105°C, and proper clock configuration using the PLL in PEE mode. The core delivers 1.25 DMIPS/MHz, enabling high-efficiency real-time processing in the MK22FN1M0AVLK12.

Does the MK22FN1M0AVLK12 include an integrated USB voltage regulator?

Yes, the MK22FN1M0AVLK12 integrates a 3.3 V, 120 mA LDO specifically for USB operation. This regulator powers the internal USB PHY and supports self-powered USB device configurations without requiring an external 3.3 V supply rail. It is enabled automatically when USB functionality is activated in the MK22FN1M0AVLK12's power management system.

What analog-to-digital converter (ADC) resources does the MK22FN1M0AVLK12 provide?

The MK22FN1M0AVLK12 includes two independent 16-bit successive approximation register (SAR) ADC modules, each supporting up to 16 input channels. Both ADCs operate concurrently with configurable resolution (8–16 bits), sampling rates up to 1 MSPS, and flexible trigger sources. The MK22FN1M0AVLK12 also integrates a 12-bit DAC and three analog comparators for comprehensive mixed-signal functionality.

What is the lowest power consumption mode supported by the MK22FN1M0AVLK12?

The MK22FN1M0AVLK12 achieves its lowest static power in Very-Low-Leakage Stop mode 0 (VLLS0) with POR detect disabled, drawing just 268 nA at 3.0 V and –40°C to 25°C. In this mode, the MK22FN1M0AVLK12 retains full register and RAM contents, supports wake-up via LLWU pins or RTC alarm, and recovers to RUN mode in 183 μs - ideal for ultra-long-life battery applications.

Is the MK22FN1M0AVLK12 pin-compatible with other K22 family members?

Yes, the MK22FN1M0AVLK12 is pin-compatible with other 80-pin LQFP variants in the K22F family, including MK22FX512AVLK12 and MK22FN512AVLK12. All share identical mechanical footprint, pin assignment, and electrical characteristics for shared signals (e.g., USB0_DP/DM, CAN0_TX/RX, ADC inputs). Firmware porting between these parts requires only flash size and feature enablement adjustments - no PCB redesign is needed for the MK22FN1M0AVLK12.
