The Voice Control HMI with RISC-V ASSP solution is a compact voice control HMI system featuring a RISC-V 100 MHz 32-bit high-performance CPU with cost-optimized small packages. This pre-programmed solution can input analog and I2S/PDM digital microphone data, actuate digital and analog outputs, and send feedback to an external host via I2C, I3C, UART, and SPI. A QSPI memory interface enables easy memory expansion. Wake-up words and commands can be customized and support multiple languages.
