i.MX RT600

Ultra-Low Power MCU with High Performance DSP for ML/AI, Voice and Audio Applications


  • High Performance, Real-time Processing
  • Low Power
  • Rich Integration
  • Advanced Security

i.MX RT series is NXP's line of crossover MCUs, bridging the gap between the traditional MCUs and the applications processor space, allowing MCU customers a path for significant performance and integration improvements, without sacrificing ease-of-use.

i.MX RT600 is the latest product in the i.MX RT series, and offers significant differentiation compared to other i.MX RT products. The i.MX RT600 is the first i.MX RT series using the Cortex-M33 core, coupled with the Cadence® Tensilica® HiFi 4 DSP.  It is optimized for consumer, low-power applications.
