This is an easy-to-use platform for Voice User Interface (VUI) solutions based on the RA family of 32-bit MCUs. The platform will be used for all VUI solutions provided by Renesas within the Renesas Ready Partner Network. The platform itself enables a local end-point inference voice recognition approach without the necessity of network connectivity.

System Benefits​:

  • A VUI solution that consists primarily of an RA Arm® Cortex®-M33 MCU
  • Up to two digital microphones and two analog microphones
  • External QSPI flash provides the ability to store voice samples and library data
  • Communication interfaces
    • PMOD interface (Type-2A/3A/6A)
    • USB Type-C and Micro-B
  • On-board Segger J-Link debugger/programmer




  • Home automation
  • Industrial automation
