It carries 512 KB of Flash program memory and 128 KB of RAM, with a full-speed USB OTG interface, 33-channel 16-bit ADC, and dual 12-bit DAC.
At 120 MHz the Cortex-M4 can execute single-cycle multiply-accumulate instructions and hardware divide. The 128 KB RAM buffers samples from the 16-bit ADC without external memory.
The Kinetis K2x family includes pin-compatible Flash-density variants such as the MK22FN256VLL12 (256 KB Flash) and MK22FN1M0VLL12 (1 MB Flash) in the same 100-LQFP package, enabling a drop-in memory upgrade or cost reduction without a PCB change.
The MK22FN512VLL12 is rated for -40 to 105 °C ambient, suitable for industrial and automotive auxiliary environments.
