AIoT on the Edge: AI-Accelerated Revolution
New Tech Tuesdays
Join Mouser's Technical Content team for a weekly look at all things interesting, new, and noteworthy for design engineers.
Published September 16, 2025
The increasing integration of artificial intelligence (AI) with Internet of Things (IoT) devices has produced a new, growing concept known as the artificial intelligence of things (AIoT). Innovative AIoT applications are expanding across industries—enabling automation, predictive maintenance, and energy optimization—and driving demand for compact, secure, and power-efficient solutions.
This trend is particularly visible in the smart home sector, where the US market alone was valued at US$28.30 billion in 2024 and is projected to reach US$99.40 billion by 2032.[1] This rapid expansion underscores the need for microcontrollers that can deliver exceptional AI performance at the edge without compromising reliability.
This week's New Tech Tuesdays explores how a new generation of microcontrollers from Renesas Electronics is meeting these demands with an AI-accelerated design built for the future of connected devices.
Edge AI Performance
Designing edge AI systems for smart homes often involves juggling multiple challenges, such as achieving high-performance processing, managing power consumption, and ensuring real-time data analysis, all within tight space and cost constraints. The latest AI-enabled microcontrollers address these challenges by combining powerful central processing unit (CPU) cores with a dedicated neural processing unit (NPU), providing an exceptional uplift in AI, machine learning (ML), digital signal processing (DSP), and scalar performance.
This integrated microcontroller architecture directly helps smart home applications by enabling on-device processing for tasks like voice command, facial recognition for security, and real-time monitoring of energy consumption. By managing these complex tasks locally on a single chip, the system reduces design complexity and ensures secure device operation, providing a more responsive and reliable user experience without relying on constant cloud connectivity. This allows smart thermostats to learn user habits more quickly, security cameras to instantly find familiar faces, and smart appliances to improve their performance in real-time, all while consuming less power.
The Newest Products for Your Newest Designs®
Renesas Electronics RA8P1 microcontrollers offer a high-performance solution for developers seeking robust AI capabilities in edge AI and IoT applications. These MCUs integrate the Arm® Cortex®-M85 and, in dual-core variants, a companion Cortex-M33 CPU core, together with the Arm Ethos™-U55 NPU. This combination delivers up to 256 giga-operations per second (GOPS) of AI acceleration and over 7300 CoreMarks of processing performance. Engineered with advanced hardware security, such as TrustZone®, cryptographic accelerators, secure boot, immutable storage, and tamper protection, these devices support secure device operation across diverse environments.
When incorporating the RA8P1 into AIoT applications, designers can rely on the EK-RA8P1 evaluation kit (Figure 1) to provide the necessary requirements and interface options for testing.
