That clock rate lands it in the mid-band of the Kinetis K20 family. The 100-LQFP (14×14 mm) package keeps the footprint manageable for a 4-layer board. ## Peripheral set — USB OTG, ADC, DAC The DMA engine and the programmable delay block (LVD, POR, PWM, WDT) offload the core for time-critical tasks.","metaTitle":"NXP MK22FN256VLL12R Kinetis K20 MCU, 120MHz, 256KB Flash, 100-LQFP","metaDescription":"NXP Kinetis K20 ARM Cortex-M4 MCU at 120MHz, 256KB Flash, 48KB RAM, USB OTG, 33-ch 16-bit ADC.
