Voice Control HMI with RISC-V ASSP

The Voice Control HMI with RISC-V ASSP 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 design 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.

System Benefits:

• Integrated, pre-programmed turnkey design adds HMI voice control capability without any user code programming
• Wide range of command input capabilities, simple programming of the target system – language independent
• Complete reference design available, supporting a large input voltage range (3.5V to 20V max)
