Renesas adds voice controlled MCU to RISC-V portfolio

Author: EIS Release Date: Apr 10, 2023

Renesas has added to its  RISC-V portfolio with an MCU for voice-controlled HMI systems based on the AndesCore D25F CPU core.

 

The 32-bit ASSP is a production-ready voice-control system solution that eliminates the need for RISC-V tools and upfront software investment.

 

Targeting residential and commercial building automation, home appliances, toys and healthcare devices, the new ASSP supports multiple languages and user-defined keywords for voice-recognition operations.

 

The foundation of a turnkey voice-control solution, the R9A06G150 is pre-programmed using specialised application code developed by independent design houses.

 

 

  Features:

• 100MHz CPU with DSP instructions, floating-point extension and cost-optimized specification
• Specialized audio PDM & SSI I/F for seamless connection to microphones and codecs
• Compatible with low-cost analog microphones and outputs
• Low power consumption helps end products to save energy for a greener environment through optimal mix of lowest active current, reduced standby current, background operation, SRAM power-off choices, fast wakeup, low power timers
• Controlled by external host I/F via SCI/Uart, SPI, I3C or I2C
• Small package support for cost and integration effectiveness (QFN 48, 32, 24)
• 256K program flash, 128K RAM, 16KB data flash
• QSPI interface for easy memory expansion
• Complete reference kit: hardware, software, tools, hardware/software datasheets, GUI manual, app notes
