Renesas Electronics Corp. has extended its RISC-V portfolio with its first microcontroller designed for voice-controlled human-machine interface systems.
Called the R9A06G150 32-bit ASSP, is a production-ready, voice-control system that eliminates the need for RISC-V tools and upfront software. The device is a turnkey voice-control solution pre-programed using specialized application code developed by independent design houses.
The device is targeted for residential and commercial building automation, home appliances, toys and healthcare devices. The device is based on RISC-V processing IP from Andes Technology Corp., which incorporates its AndesCore D25F CPU core based on the AndeStar V5 architecture.
The RISC-V voice-control ASSP pre-programmed with a dedicated application code developed by leading independent design house, Cyberon, an expert in voice-recognition technology and Orbstar, a systems integrator.
Other features of the microcontroller include:
- 100 MHz CPU with DSP instructions
- Specialized audio PDM and SSI
- Compatible with low-cost analog microphones and outputs
- Low power consumption
- Controlled by external host
- Small package support
- 256 KB program flash
- QSPI interface for easy memory expansion
