RISC-V Unleashes Your Imagination


Since October 2020, Renesas has been officially active in the RISC-V microcontroller space and successfully launched two ASSP products, for motor control and voice-driven HMI systems. Now a general-purpose MCU enhances the RISC-V portfolio. It is the first MCU using a RISC-V core developed internally at Renesas. The R9A02G021 general-purpose microcontroller features an interesting mix of an... » read more

Build Secured And Cost Effective Next-Generation Actuator And Sensor Applications Based On The Latest E/E Architectures


Automotive E/E architectures have undergone remarkable changes in recent years influencing actuator and sensor applications such as body control (lights, windows, and mirrors, etc.), motor control such as engine pumps and fans, and sensor control. Traditionally, these applications have used small and low-cost 16-bit microcontrollers (MCUs) but now they need more advanced 16-bit MCUs. In this wh... » read more
