The Austin-based company, founded in 2010, has raised $36.9 million from eight investors in eight rounds, according to its Crunchbase profile.

Kleiner Perkins Caufield & Byers (KPCB) led the latest funding round which was supported by existing investors including Austin Ventures, Mercury Fund, and ARM Holdings. KPCB partner Wen Hsieh will be joining Ambiq Micro’s board.

Ambig Micro plans to use the funding to further develop its SPOT platform, which “dramatically reduces the energy consumption of semiconductors by reducing the voltage level at which switching occurs inside the chips,” according to a news release. It also makes real time clocks. The company is targeting the Internet of Things marketplace and the wearables marketplace, which require energy efficient and long-last batteries.

“KPCB’s Low Power Everywhere initiative believes that in a world where consumers and businesses are always on, there’s an increasing need for devices with improved energy efficiency and battery life,” KPCB partner Wen Hsieh said in a news release. “Ambiq Micro has developed a 10X lower power MCU for mobile, wearables and IoT devices. We’re excited to back an exceptional team and to help them quickly scale this opportunity.”
