At CES today, Texas Instruments released new automotive chips focused on in-cabin sensing and audio processing. The AWRL6844 60GHz millimeter-wave radar sensor integrates four transmitters and four receivers on a single chip, processing data through onboard AI algorithms. Through micro-movement analysis, the sensor achieves 98% accuracy for occupant detection and over 90% accuracy for child presence detection. The system reduces implementation costs by approximately US$20 per vehicle compared to traditional sensing technologies.
The company’s new automotive audio processors, AM275x-Q1 MCUs and AM62D-Q1, incorporate a vector-based C7x digital signal processor core alongside Arm cores and memory on a single system-on-chip. The C7x core processes audio algorithms with matrix multiply acceleration for neural processing. The processors handle spatial audio, active noise cancellation, and Audio Video Bridging over Ethernet networking protocols.
The TAS6754-Q1 audio amplifier introduces one-inductor modulation technology, reducing component count while maintaining Class-D amplifier performance specifications. The amplifier includes integrated real-time load diagnostics and achieves equivalent audio quality metrics with half the number of inductors compared to conventional Class-D designs.
The radar sensor combines occupancy monitoring, seat belt reminder functionality, and intrusion detection capabilities into a unified hardware platform. Its AI accelerator and DSP enable real-time processing of high-resolution sensing data. The system adapts to environmental conditions through intelligent scanning algorithms to minimize false detection events.
