The ADSP-BF706 digital signal processor and Electric Vehicle Warning Sound System (EVWSS) firmware enables automobile manufacturers to comply with future safety regulations mandating external engine sound for EVs and HEVs traveling at low speeds. Featuring a complete hardware and firmware reference design, the solution can be scaled for high performance with the ADSP-BF706 or entry-level applications with the ADAU1450 Digital Audio Processor.

The ADSP-BF706 can also be used to create in-cabin engine sound to contribute to an improved driving experience. The device uses memory mapped quad SPI memory providing faster and simpler access to the stored audio files used to create the engine sound, and can access up to 24 WAV files simultaneously.

When using the ADAU1450, developers can use the company’s Sigma Studio integrated development environment (IDE) to graphically tune the audio sound. A new release of the IDE supporting the ADSP-BF706 is expected later this year. In addition, a low-cost CAN software stack runs on the ADSP-BF706 to help customers quickly build automotive-grade prototypes.

The ADSPP-BF706 is available now in an 88-Lead LFCSP for $8.38/1,000 qty. The ADAU1450 is available now for $4.22/1000 qty and is packaged in a 72-Lead LFCSP.
