In July 2018, West fountain Global Fund LP ("West Fountain") and Shenzhen Capital Group Company (“SCGC") completed E round investment in Ambiq Micro, Inc. ("Ambiq Micro"), an American chip design company for the Internet of things (IoT). Other investors included EDBI. Prior to that, West Mountain and SCGC also participated in D round financing of Ambiq Micro in 2017.

Ambiq Micro is an Internet of things chip design company in the United States. Founded in 2010, the company is committed to developing hybrid signal solutions for wireless electronic products, and also to develop ultra-low power chip products. Breakthrough technologies developed by Ambiq Micro are based on its patented Sub Threshold Power Optimized Technology, SPOT™, which can significantly reduce the power consumed by semiconductor devices.

The SPOT platform uses transistors operating at sub threshold voltage (below 0.5V), rather than transistors that have been "on" at 1.8V. The platform uses the leakage current of "off" transistors to calculate in the digital and analog fields. The patented technology is implemented by industry standard CMOS technology, overcoming the noise sensitivity, temperature sensitivity and process drift challenges related to sub threshold voltage switching. The Apollo1 and Apollo 2 series ultra-low power MCU chips that Ambiq Micro has launched are also based on the same platform.

Mr. Mark Foley, CEO and President of Ambiq Micro, said: "In the past few years, microcontrollers have become more and more energy efficient, but no one has been able to provide products close to the level of power improvement achieved by SPOT platform. This technology has been verified in real-time clock products in the past two years, and now it is applied to Apollo MCU devices, providing a breakthrough in battery life that portable device designers have been dreaming of. Looking ahead, we expect that the power consumption of semiconductor devices will be reduced by half every two years, and that's where the trend starts. "
