NXP MK22FN1M0AVLK12R is an ARM Cortex-M4 MCU clocked at 120 MHz, with 1 MB Flash and 128 KB RAM. It integrates a 27-channel 16-bit ADC, a single 12-bit DAC, and a full peripheral set including CANbus, USB OTG, and an external bus interface (EBI/EMI).
120 MHz Cortex-M4 — throughput for control and signal processing
The 120 MHz core speed handles real-time control loops with DSP extensions (single-cycle MAC, SIMD) and floating-point unit for sensor fusion or motor FOC without an external co-processor.
1 MB Flash / 128 KB RAM — firmware and data buffer sizing
1 MB of program Flash supports complex firmware stacks — a full CANopen or Modbus TCP stack plus application code fits without external memory. The 128 KB SRAM (organized as 128K x 8) provides working space for data buffers, communication packets, and real-time variables. Designs that require larger data arrays (e.g., 2D graphics frame buffers) will need external RAM via the EBI/EMI interface.
Industrial temperature range — -40°C to 105°C
Rated for -40°C to 105°C ambient. The 105°C ceiling covers derating headroom for self-heating at 120 MHz.
Active lifecycle — current production, no LTB watch
NXP lists the MK22FN1M0AVLK12R as Active. No last-time-buy or end-of-life notice is on record. For BOM freeze and multi-year production runs, this part is in current manufacturing with standard lead times through distribution.
Connectivity and peripheral set
On-chip CANbus (FlexCAN) and LINbus support automotive and industrial fieldbus nodes. USB OTG enables dual-role host/device operation for data logging or firmware updates. The EBI/EMI interface allows glueless connection to external SRAM, NOR Flash, or FPGAs. DMA offloads peripheral data movement from the Cortex-M4 core, preserving throughput for control tasks.
