R9A06G150 is an application-specific signal processor that allows engineers to quickly and easily integrate voice recognition into their products.

R9A06G150 is the first RISC-V MCU from Renesas that is designed for voice-controlled HMI (human-machine interface) systems. The R9A06G150 is a 32-bit ASSP (Application Specific Signal Processor) that eliminates the requirement for RISC-V tools and upfront software investment, therefore, making it a cost-effective, production-ready voice-control system solution. Furthermore, the new ASSP supports multiple languages and user-defined keywords for voice-recognition operations. The R9A06G150 is suitable for use in applications such as residential and commercial building automation, home appliances, toys and healthcare devices.

The Renesas R9A06G150 is based on a 100MHz CPU with digital signal processing (DSP) instructions. It is a specialized audio PDM and SSI interface that offers seamless connection to microphones and codecs, moreover, this HMI solution has low power consumption and is compatible with cheap analog microphones and outputs too. R9A06G150 is pre-programmed using specialized application code developed by independent design houses while the R9A06G150 voice-control HMI ASSP is based on RISC-V processing IP from Andes Technology Corp.

“Renesas continues to broaden our RISC-V MCU/MPU offering, in this case by delivering designers an innovative voice-command HMI with pre-developed software that shortens development time and time to market,” said Roger Wendelken, Senior Vice President in Renesas’ IoT and Infrastructure Business Unit. “Through close collaboration with the RISC-V partner ecosystem, this flexible, scalable ASSP solution allows customers interested in voice control to support different application classes on the same MCU hardware platform.”
