Kinetis K20 MCU — 120 MHz Cortex-M4 with 512 KB Flash
The NXP MK22FX512VLL12 is a 32-bit ARM Cortex-M4 microcontroller clocked at 120 MHz with 512 KB of Flash and 64 KB of RAM. It integrates CAN, USB OTG, EBI/EMI, I²C, SPI, and DMA.
What the 120 MHz core and 512 KB Flash mean for your BOM
At 120 MHz, the Cortex-M4 handles single-loop motor control or CAN-based sensor fusion. The 512 KB Flash holds a full application stack.
Connectivity and analog features
The part includes a CAN controller, USB OTG with on-chip PHY, and an external bus interface that can connect to parallel LCDs or external SRAM. DMA offloads peripheral-to-memory transfers without CPU intervention, which matters for high-data-rate USB or SPI traffic.
