Ambiq Micro was founded in 2010 on the notion that extremely low power semiconductors are the key to the future of electronics. They developed a patented Subthreshold Power Optimized Technology (SPOT™) platform that dramatically reduces the amount of power consumed by semiconductors. Normal CMOS processes are working with an internal core voltage above the threshold voltage a transistor needs to make a logical low or high decision. Therefore most cores are working at 1.8V or 1.2V depending on the CMOS process. By applying SPOT™ on a standard CMOS process, the internal core voltage can be minimized to 0.5V. While the energy consumption is proportional to the squared voltage, SPOT™ can reduce energy usage by up to 13 times!
