Description
The R9A06G150 RISC-V MCU ASSP is specifically optimized for voice and sound triggered human machine interfaces. Alongside ecosystem partners, this provides a complete, production-ready keyword spotting and recognition system solution. With 100 MHz performance, 256/128/16 KB of Flash/RAM/DataFlash memory, advanced digital and analog microphone input and playback interfaces, small package, and memory expansion options, the R9A06G150 provides the foundation for a turnkey voice HMI solution including Renesas specialized partners' software.
The chip is manufactured by Renesas and pre-programmed at the factory with specialized application code developed by IDHs (independent design houses), third parties with demonstrated specialized expertise in the development and integration of keyword spotting and voice driven user interfaces with proven customer support capability, to bring the projects to completion and secure the successful transition to the mass-production stage. The strongly collaborative solution with the IDH is fundamental value proposition and the key to success. The end-product is composed of the combination of Renesas hardware and third-party software.
