Our advanced mixed-signal LSIs feature low power consumption, high speed, and high precision. Mixed-signal LSIs play an essential role in bridging the gap between the analog information of the natural world and the digital information of electronic systems.
Applications range from mobile communications including smartphones to automobiles, industrial equipment, and infrastructural equipment.
The electronic compass, an advanced product which combines magnetic sensors and LSIs in a single device, finds widespread use in smartphones and other portable devices.
Hall elements are high-performance magnetic sensors used for control of brushless motors in optical disc drives and air conditioner fans, for image-stabilization mechanisms in digital cameras and smartphones, as well as many other areas.
Hall ICs, comprising a combination of Hall elements and signal processing circuits, are used for mobile phone open/close detection switches and automobile power windows.
Utilizing the thin-film compound semiconductor technology gained through experience in magnetic sensors, we are developing infrared (IR) sensors with smaller size for an expanding range of applications.
Asahi Kasei Microdevices (AKM) traces its roots to the 1980s, when the Asahi Kasei Group began developing its semiconductor business. Since then, we have continued to grow by providing customers with unique products which combine elements based on compound semiconductor technology used for magnetic sensors with ASIC technology based on silicon semiconductors. In recent years, we are making new proposals to meet the needs of the IoT era by focusing particularly on sensing and voice solutions incorporating software technology, as well as various solutions of invisible optics utilizing compound semiconductor technology.
Among individual products, our magnetic sensors for controlling motor rotation, and our audio & voice ICs that provide high-quality sound with low power consumption, have gained strong recognition among customers around the world, and azimuth angle sensors (e-compasses) that are essential for mobile devices such as smartphones and tablets are also widely known as a product practically originated by AKM. Moreover, AKM has continued to provide unique products to customers such as sensor devices and motor driver ICs used in image stabilization and autofocus systems for cameras, infrared sensors featuring ultra-small size and fast response for static human detection and CO2 detection—all combining packaging, software engineering, testing, and implementation support technology in addition to circuit technology and material technology.
In addition to products for mobile communications and consumer electronics, we are also expanding in the fields of automotive electronics, residential equipment, and industrial equipment. AKM continues to advance while keeping track of the latest information in the semiconductor industry for the Asahi Kasei Group as a comprehensive manufacturer centered on chemistry, working in coordination with other business units of Asahi Kasei to propose innovative new value.
Throughout our history of development and growth, we have always been guided by the needs of our customers and end-users, and we remain committed to working together with you to achieve the solutions that truly meet your requirements and those of your customers. We look forward to continuing to serve you with superior AKM products.
