The NXP MK22FN512VLH12R is a 32-bit ARM Cortex-M4 MCU clocked at 120 MHz with 512 KB Flash and 128 KB RAM. It integrates USB OTG, multiple serial interfaces (I²C, SPI, UART/USART, IrDA), a 22-channel 16-bit ADC, and a 2-channel 12-bit DAC in a 64-LQFP package. The -40 to 105 °C industrial temperature range qualifies it for motor drives, outdoor telecom, factory automation, and engine-bay electronics where extended thermal tolerance is required.
Core speed and memory — sizing the headroom
The 40 GPIOs, combined with the 22 ADC channels, suit designs that need both digital I/O and analog measurement on a single chip.
