FAQ

What is the maximum operating frequency of the MK22FN1M0VLH12?

The MK22FN1M0VLH12 operates at a maximum core and system clock frequency of 120 MHz, achieved using the on-chip PLL with external crystal or internal reference. This frequency is supported across the full industrial temperature range (–40°C to 105°C) and enables full-speed USB 2.0 (12 Mbps) and CAN 2.0B timing compliance without overclocking. The MK22FN1M0VLH12 maintains this speed while executing from flash with cache enabled.

Does the MK22FN1M0VLH12 include a hardware floating-point unit?

Yes, the MK22FN1M0VLH12 integrates a full IEEE-754 compliant single-precision floating-point unit (FPU) as part of its ARM Cortex-M4 core. This FPU accelerates trigonometric, exponential, and matrix operations essential for motor control, sensor fusion, and digital signal processing - eliminating software emulation overhead. The MK22FN1M0VLH12's FPU is accessible via standard CMSIS-DSP library calls and GCC arm-none-eabi toolchain intrinsics.

What USB capabilities does the MK22FN1M0VLH12 support?

The MK22FN1M0VLH12 supports USB 2.0 Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps) On-The-Go (OTG) operation with integrated 3.3 V/120 mA LDO regulator. It implements USB device, host, and OTG roles via configurable controller registers and supports standard classes including CDC ACM, HID, and MSC. The MK22FN1M0VLH12 requires no external USB voltage regulator and includes internal pull-up resistors and differential termination.

What low-power modes are available on the MK22FN1M0VLH12?

The MK22FN1M0VLH12 offers seven low-power modes: RUN, WAIT, VLPR, VLPW, STOP, VLPS, LLS, and four VLLS sub-modes (VLLS0–VLLS3). Its lowest power state, VLLS0 with POR detect disabled, draws just 268 nA at 3.0 V while retaining full register and RAM content. Wakeup occurs in ≤5 μs via LLWU pins, RTC alarm, or USB activity - making the MK22FN1M0VLH12 ideal for battery-powered edge sensors.

Is the MK22FN1M0VLH12 pin-compatible with other Kinetis K22 devices?

Yes, the MK22FN1M0VLH12 shares the same 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) and pinout with MK22FX512VLH12 and MK22FN512VLH12. All three devices maintain identical signal assignments for power, ground, USB, CAN, ADC, and GPIO functions - enabling direct PCB footprint reuse and firmware migration between flash variants. The MK22FN1M0VLH12 requires no layout changes when upgrading from 512 KB flash versions.
