RISC-V ASSP adds voice control 

Developed in partnership with RISC-V ecosystem partners, the R9A06G150, 32bit ASSP is claimed to be the first RISC-V microcontroller designed for voice-controlled HMI (human-machine interface) systems. 

It provides a cost-effective, production-ready voice control system that eliminates the need for RISC-V tools and upfront software investment.

The ASSP can be designed into devices used in residential and commercial building automation, home appliances, toys and healthcare devices. It supports multiple languages and user-defined keywords for voice recognition. The R9A06G150 is pre-programmed using specialised application code developed by independent design houses, added Renesas.

The R9A06G150 voice-control HMI ASSP is based on RISC-V processing IP from Andes Technology which incorporated its AndesCore D25F CPU core based on the AndeStar V5 architecture. “The 32-bit AndesCore D25F was engineered to deliver high per-MHz performance in a small silicon footprint,” explained Frankwell Lin, Andes’ chairman and CEO. 

Renesas will deliver the first RISC-V voice-control ASSP pre-programmed with dedicated application code developed by Cyberon, an independent design house, specialising in voice-recognition technology, and Orbstar, a systems integrator specialising in embedded solutions Segger Microcontroller’s ecosystem, including Embedded Studio and J-Link will provide support for the voice-control ASSP. 

The R9A06G150 voice control HMI ASSP features a 100MHz CPU with DSP instructions and floating-point extension. Low active current, reduced standby current, background operation, SRAM power-off choices, fast wakeup and low power timers contribute to low energy consumption. The ASSP is controlled by external host I/F via SCI/Uart, SPI, I3C or I2C.

It also features 256kbyte, 128kbyte RAM and 16kbyte data flash memory. There is also a QSPI (queued serial peripheral interface) for memory expansion.

The R9A06G150 32-bit MCU voice-control HMI ASSP is available now in a 24-, 32- or 48-lead HWQFN package.  

Renesas also offers a reference kit for the ASSP, which includes hardware, software, tools, hardware/software datasheets, GUI manual and app notes.
