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

Ambiq Micro’s proprietary SPOT platform reduces the energy consumption of semiconductors by reducing the voltage level at which switching occurs inside the chips. The company already manufactures and markets real-time clocks (RTCs) using this technology and a microcontroller (MCU) family, manufactured using the same standard CMOS process, will be announced within the next few weeks. The MCUs will target Internet of Things (IoT) applications, particularly wearable electronic devices, where energy savings will translate into much longer battery life.

Battery life in many applications, especially those in the wearable and IoT markets, fall short of what is desired and have hindered widespread deployment of these products. Ambiq Micro’s devices claim to solve the problem, enabling the development of products with much longer battery life than is currently possible. Some will run for months or even years between battery charges. Other products will benefit from the addition of new features that would not otherwise be achievable within

restrictive power budgets. The potential to use smaller batteries will also provide more creative freedom for products designers too, allowing them to explore form factors that were not previously possible and to make smaller, lighter devices.
