NXP smart speaker is based on an i.MX 8M processor and provides a Class-D audio amplifier with a SpeakerBoost acoustic enhancement and protection algorithm in on-chip DSP with temperature and excursion protection. By using an internal adaptive DC-to-DC converter, you get ample headroom for major improvements in audio quality.

The i.MX 8M processor provides advanced audio, voice and video processing, and low-power capabilities that create scalable, safe and secure applications.
