Kinetis K22 at 120 MHz — what the core speed means for the loop
The NXP MK22FN1M0VMC12R is an ARM Cortex-M4 32-bit single-core MCU clocked at 120 MHz, with 1 MB Flash and 128 KB RAM.
Analog front-end and connectivity set
The connectivity block includes CANbus, USB OTG, I²C, SPI, UART, IrDA, and an EBI/EMI bus.
That means NXP has flagged it for eventual phase-out; new projects should target a current Kinetis K2x or K6x device. For existing BOM lines already qualified to this order code, the NRND status is a signal to evaluate a last-time-buy window and qualify a pin-compatible or drop-in replacement. The part remains available through independent distribution for production replenishment and service spares, but the allocation window is narrowing — procurement should lock in a forward cover position now rather than waiting for a shortage premium to develop.
Supply voltage spans 1.71 to 3.6 V.
