  • Full-speed USB 2.0 compatible device, supporting USB audio class (UAC) 1.0
  • USB HID and endpoint 0 control interfaces
  • Flexible peripheral interface
    • Programmable digital general inputs and outputs
    • I2C interface for system control and local peripheral control
    • I2S slave interface input and output audio data
    • SPI master interface for control and inquiry of local SPI slave devices

Firmware Management

  • Option to boot from QSPI flash
    • Default firmware image for power-on
    • Firmware image updates provided over USB
    • Fixed user data during firmware upgrade cycles
    • User-configurable programming for SPI peripherals
  • Option to boot via SPI from local host processor

As a cost-effective voice interface solution for smart devices, not only may it be necessary for Automated Speech Recognition (ASR) applications, but it could also be used for voice calls (Communication); it is particularly optimized for ASR front-end processing, greatly improving performance in voice interrupt and recognition capabilities. Given its comprehensive features, the following or similar smart devices are recommended for its application:

  • Navigation robots (ASR)

  • Medical equipment (ASR)

  • Fitness equipment (ASR)

  • Large-screen advertising machines (ASR)

  • Lecture streaming (Comms)

  • Camera microphones (Comms)

  • Smart speakers (ASR)

  • Conference treasure (comms)
