General-Purpose 32-bit RISC-V MCU Core Expands Design Freedom

The microcontroller sector is evolving in an exciting direction by providing designers with a growing menu of choices tailored to their performance and power requirements. Unlike the classic 1990s debate between the merits of x86 (CISC) and PowerPC (RISC) CPU architectures, there is plenty of room under the MCU tent for competing – and complementary – processor cores. The common denominator... » read more

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

Reducing Noise Issues In Microcontroller Systems: Part 1

In my ideal digital world, of which I often dream, signal voltage margins are always positive, signal timing margins are always positive, power supply voltages are always within the operating voltage range, and our environment is completely benign. Unfortunately, none of us live in this ideal world, no matter how much I would like to. The real world is dirty and noisy, and the power distribu... » read more

Options Widen For Optimizing IoT Designs

Creating a successful IoT design requires a deep understanding of the use cases, and a long list of tradeoffs among various components and technologies to provide the best solution at the right price point. Maximizing features and functions while minimizing costs is an ongoing balancing act, and the number of choices can be overwhelming. The menu includes SoC selection, OS and software proto... » read more

Renesas / Cyberon Speech Recognition

Traditional voice or speech recognition technology is based on a trained model with specific words or phrases. Natural language processing is word-order independent. This requires large computing power to run the real time data through a neural network. The Cyberon approach is different, allowing the algorithms to run on a small, general purpose MCU.
