The NXP MK22DX128VLF5 is a 32-bit ARM Cortex-M4 MCU clocked at 50 MHz with 128 KB Flash and 32 KB RAM.
At 50 MHz the Cortex-M4 delivers throughput for real-time control loops and data logging over USB. The 128 KB Flash holds a firmware stack with room for a bootloader; the 32 KB RAM handles double-buffered ADC captures or a small RTOS heap.
The MK22DX128VLF5 is rated for a 50 MHz core clock, which defines the maximum instruction throughput for the ARM Cortex-M4 core.
The MK22DX128VLF5 is supplied in a tray, RoHS-compliant per NXP's standard material declaration. Specific REACH, UL, or IEC certificates can be requested at RFQ time.
