Ambiq Micros & RTCs combine high performance with ultra-low power consumption

Ultra-low power MCUs, BLE and RTCs

Ambiq Micro was founded in 2010 on the notion that extremely low power semiconductors are the key to the future of electronics.

Ambiq Micro 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!

SPOT platform voltage vs time

By applying SPOT™, Ambiq produces the world’s lowest power real-time clock (RTC) and microcontroller (MCU) family.
