FAQ

What is the maximum operating frequency of the MK22FN1M0AVLK12R core?

The MK22FN1M0AVLK12R 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 ≥ 2.7 V, ambient temperature ≤ 105°C, and proper decoupling. At 120 MHz, the core delivers 1.25 Dhrystone MIPS per MHz, enabling high-throughput signal processing in applications such as motor control and sensor fusion. The MK22FN1M0AVLK12R supports dynamic clock scaling down to 4 MHz in VLPR mode for ultra-low-power operation.

Does the MK22FN1M0AVLK12R include hardware security features?

Yes, the MK22FN1M0AVLK12R integrates several hardware security features including a dedicated hardware CRC-32 module for fast data integrity verification, a 128-bit unique identification number per chip for device authentication, and a memory protection unit (MPU) supporting multi-master access control. It does not include AES encryption engines or secure boot ROM; those capabilities are found in higher-tier Kinetis families like KE1x or LPC55S. For MK22FN1M0AVLK12R, security relies on MPU-enforced isolation, CRC-checked firmware updates, and tamper-detect-capable GPIOs.

What are the USB power requirements for the MK22FN1M0AVLK12R?

The MK22FN1M0AVLK12R integrates a USB 2.0 LS/FS OTG controller with an embedded 3.3 V, 120 mA LDO regulator. When operating as a USB device, it can be powered directly from the USB VBUS line (4.4–5.25 V), and the internal LDO supplies regulated 3.3 V to the USB PHY and core logic. As a USB host, the LDO powers external peripherals. No external regulator is needed for basic USB functionality. The MK22FN1M0AVLK12R also supports USB Device Charger Detect (DCD) for identifying wall adapters and charging ports.

Can the MK22FN1M0AVLK12R operate from a single 1.8 V supply?

No, the MK22FN1M0AVLK12R requires a minimum supply voltage of 1.71 V but is not guaranteed to operate reliably at 1.8 V across its full specification range. Its flash programming and analog modules require VDD ≥ 2.7 V for full functionality. While some low-power modes (e.g., VLPR) may function near 1.8 V, the datasheet specifies 1.71–3.6 V as the absolute operating range, with 2.7–3.6 V recommended for full peripheral enablement and 120 MHz operation. For true 1.8 V–compatible MCUs, consider NXP's LPC800 or Kinetis KL series.

How many analog-to-digital converter channels does the MK22FN1M0AVLK12R support?

The MK22FN1M0AVLK12R integrates two independent 16-bit SAR ADC modules (ADC0 and ADC1), each supporting up to 16 single-ended or 8 differential input channels-totaling 32 configurable analog inputs. Both ADCs support hardware averaging, programmable sample time, and simultaneous sampling triggered by FlexTimer or external events. They share a common voltage reference but operate autonomously, enabling concurrent acquisition for motor phase current and bus voltage monitoring. The MK22FN1M0AVLK12R does not include a third ADC; additional channels require external multiplexing or external ADCs.
