The MK22FX512VMC12 runs an ARM Cortex-M4 at 120 MHz, a 32-bit single-core. The 512 KB Flash and 64 KB RAM support control-loop firmware.
NXP lists the MK22FX512VMC12 as NRND. The part is available through existing production and surplus channels. Pin-compatible siblings with larger Flash or RAM are active parts.
The MK22FN1M0AVMC12 (1 MB Flash) and MK22FN256VMC12 (256 KB Flash) share the same 121-MAPBGA footprint, peripheral set, and supply range. Both are active parts and suitable for new designs.
The core runs at 120 MHz, which is the ARM Cortex-M4's rated maximum for this part. That clock drives the DSP and FPU throughput for real-time control loops.
