ICs
Achieving Renewed Growth Through Technological Enhancement and Profitability Improvement
At present, we are focused on the field of solutions for AI servers. While we got off to a slightly later start than our competitors, we are working on rapid product deployment that includes joint endeavors. We combine ICs and power devices to provide solutions that cover a wide range, from high to low voltage. In order to demonstrate our surefooted technological prowess in applications such as power management and motor drivers, it is essential that we reinforce system and application technologies in addition to product development. We will actively utilize partnerships with external partners as well and take action with a sense of urgency.
ROHM’s possession of diverse portfolio of power devices that include SiC, Si-MOSFET, Si-IGBT, and GaN-HEMT in addition to ICs for power supplies and motors give it an advantage. Our understanding is that very few companies can match our product mix in this respect. While having a lineup with high added value at the ready for standalone ICs as well is important, we are able to further elevate our value proposition for customers by developing ICs optimized as solutions in combination with our own power devices. With ICs and power devices developed collaboratively as a solution, we pursue ease of use for customers and improved system performance, enabling us to deliver comprehensive added value that is not easily duplicated by our competitors.

Making it easier to detect faults early using microcontrollers equipped with AI functionality, thereby contributing to stable equipment operation
In recent years, amid the need for the efficient operation of equipment and machinery, the application of AI to predict and detect faults and improve maintenance efficiency have emerged as key themes. On the other hand, conventional AI processing models necessitate network connectivity, high-performance CPUs, and so forth, which posed challenges with cost and installation environments. To address such challenges, as of March 2025, ROHM has developed the industry’s first*1 microcontroller equipped with AI functionality, which makes both learning and inference possible on the microcontroller itself without requiring a network. This product utilizes a proprietary AI accelerator*2 to achieve AI processing speeds 1,000 times faster than ROHM’s microcontrollers employing conventional software-based systems (Condition: theoretical value at 12 MHz operation). It is also able to flexibly accommodate disparities across installation environments and devices. Additionally, ROHM offers a simulation tool online, called “Solist-AI™ Sim,” that makes it possible to verify the product’s effects before implementing it. We also have a model development and implementation support structure in place through an ecosystem in collaboration with partner companies. In this way, by detecting signs of device failure before it occurs and lowering both maintenance costs and the risk of line stoppage with its microcontrollers equipped with AI functionality, ROHM contributes to the stable operation of equipment and devices and to the further enhancement of their efficiency.
- *1 As of March 18, 2025. According to research by ROHM on microcontroller products.
- *2 Dedicated hardware that improves processing speeds by using hardware to handle processing that would otherwise be left to the processor (CPU) using software when realizing AI functionality.
