Ambiq Micro Apollo 1 – Technology and availability

Ambiq Micro developed a patented Subthreshold Power Optimized Technology (SPOT™) platform that dramatically reduces the amount of power consumed by semiconductors. By applying SPOT, Ambiq Micro produces the world’s lowest power real-time clock (RTC) and microcontroller (MCU). Rather than using transistors that are turned all the way “on”, subthreshold circuits use the leakage of “off” … [Read more…]
