NXP Semiconductors i.MX RT106A Crossover Processor is a solution specific variant of the i.MX RT1060 family of MCUs, targeting cloud-based embedded voice applications. It features NXP’s advanced implementation of the Arm® Cortex®-M7 core, which operates at speeds up to 600MHz to provide high CPU performance and best real-time response. i.MX RT106A based solutions enable system designers to easily add voice control capabilities to a wide variety of smart appliances, smart home, smart retail, and smart industry devices.

The i.MX RT106A is licensed to run NXP turnkey voice-assistant software solutions, which may include:

  • Far-field audio front-end softDSP
    • Acoustic echo cancellation
    • Ambient noise reduction
    • Beamforming
    • Barge-in
    • Playback processing
    • Codecs
  • Wake-word inference engine
  • Media player / streamer
  • MQTT, lwIP, TLS
  • Discovery and onboarding
