SiTime and Renesas’ consolidated subsidiary, Renesas Electronics America Inc., have signed a definitive agreement whereby SiTime will acquire certain assets related to Renesas’ timing business. The acquisition accelerates SiTime’s path to $1 billion of revenue as the premier pure-play precision timing company with an industry-leading portfolio to fully meet customers’ needs for high-performance timing products. Additionally, the companies have signed a partnership MoU to explore SiTime’s MEMS resonator integration into Renesas’ embedded computing products.
Rajesh Vashist, chairman and CEO of SiTime, said: “This acquisition is a monumental milestone toward fulfilling our vision to transform the timing market and solve our customers’ toughest timing challenges. With Renesas’ timing business, we will increase our clocking portfolio by more than 10x and extend our reach in the fastest growing applications in the timing market, including comms, enterprise and data centre. Notably, these applications are expected to represent more than 60% of SiTime’s revenue, post-acquisition. We are confident that the acquisition will deliver exceptional value for our shareholders as we build on our strong record of financial performance, as underscored by our 2025 results announced today.”
The business being acquired is the preeminent brand in clocking with a 30-year legacy of highly differentiated clocking products and an enviable financial profile. It has delivered sustained financial performance of approximately 70% gross margin. It serves over 10,000 customers, with nearly 75% of revenue in the AI-data centre-comms segment and the remainder in industrial and automotive. In the 12 months following the close of the transaction, the business is expected to generate $300 million in revenue, catalysed by SiTime’s sales and go-to-market expertise.
Hidetoshi Shibata, CEO of Renesas, said: “This transaction allows Renesas to sharpen its focus on embedded compute leadership while ensuring our customers have access to SiTime’s cutting-edge MEMS timing technology. We look forward to exploring opportunities for strategic collaboration with SiTime to deliver integrated solutions that power the next generation of intelligent devices that demand performance and efficiency. This milestone is another step forward toward our 2035 Aspiration and becoming a top-three embedded semiconductor solution supplier. Throughout this process, we remain fully committed to supporting our employees, customers and partners, and ensuring a smooth transition.”
Vashist continued: “One of SiTime’s strategies is to integrate our resonators into MCUs and power management ICs, among other SoCs, to provide size, performance and power benefits to semiconductor companies. We are excited about the additional value that could be created for customers and the start of this multi-year revenue opportunity for SiTime.”
SiTime’s Titan MEMS resonators uniquely enable integration where the bare die can be combined with Renesas’ MCU or SoC die into a single package. This eliminates the complications associated with having the resonator on the system board and also saves space and simplifies design. The resulting next-generation products could unlock new possibilities in many applications in AI data centres, industrial equipment including robots, ADAS systems in cars, and wearables, where performance, energy efficiency, and miniaturisation are critical.
