Product details

The NXP MK22FX512AVLL12 is an ARM Cortex-M4 MCU clocked at 120 MHz, with 512 KB Flash and 64 KB RAM. That core speed places it above the 100 MHz threshold where software FFTs and motor-control loops become practical without an external DSP.

Industrial temperature grade and connectivity

The dual CANbus interfaces support redundant or multi-bus architectures common in vehicle and factory networks. USB OTG adds host/device flexibility for data logging or firmware updates via a USB stick. The 33-channel 16-bit ADC covers multi-sensor acquisition without external muxing; the single 12-bit DAC provides an analog output for setpoint control or signal generation.

Package and supply

Housed in a 100-LQFP (14×14 mm) surface-mount package with 66 I/O.

Frequently asked questions

What is the closest pin-compatible alternative to MK22FX512AVLL12?
