About Intersil

A Renesas Company

Intersil's customers build the products and applications of the future in the industrial, infrastructure, mobile computing, automotive and aerospace markets. Our advances in power management help them improve efficiency, power density and battery life. 

Intersil is now a Renesas Company

We’re excited to complete our merger with Renesas, a global leader in microcontrollers and embedded devices.

Intersil will continue to provide the great power and precision analog products you trust. And now, you’ll be seeing our power products paired up with processors and other Renesas devices, expanding our ability to provide complete system solutions that are small, power efficient and easy-to-use. We look forward to working with you under this larger umbrella and becoming your partner in your next design.

Intersil has leveraged a deep portfolio of intellectual property, a history of design and process innovation and a system-level view to deliver unique benefits for the latest electronic systems. Intersil’s customers have been recognized as innovators in their chosen markets, and our IC solutions formed the building blocks of the latest devices adding intelligence, mobility and true energy efficiency.

We were formed in August 1999 when we acquired the semiconductor business of Harris Corporation and began operating as Intersil Corporation. That semiconductor business included product portfolios and intellectual property dating back to 1967 when semiconductor companies were just emerging in Silicon Valley. That history of leadership continued as the company evolved, and in early 2000, Intersil went public in what was then the largest semiconductor IPO in US history.

Since then, the company has developed market leadership in power management and precision analog technology for many of the most rigorous applications in the computing, consumer and industrial markets. The company supplies a full range of power IC solutions including battery management, computing power, display power, regulators and controllers and power modules; as well as precision analog components such as amplifiers and buffers, proximity and light sensors, data converters, timing products, optoelectronics and interface products. As a major supplier to the military and aerospace industries, Intersil’s product development methodologies reflect experience designing products to meet the highest standards for reliability and performance in challenging environments.

We look forward to partnering with Renesas to continue providing the same sense of commitment to our customers, and to be a part of the next 50 years of semiconductor innovation.
