Apollo 2 is the latest addition in the ultra-low power Apollo microcontroller family. This highly integrated MCU reduces power consumption by more than 50% compared to the first generation Apollo MCU, therefore empowering users with more processing capability with an even lower power budget. Apollo 2 opens door for enhanced applications performing complex context detection, gesture recognition, and activity monitoring with longer battery life in wearable electronics, activity & fitness monitors, IoT devices, and wireless sensors. All Apollo series MCUs take full advantage of Ambiq Micro’s patented Subthreshold Power Optimized Technology (SPOT) Platform, setting a new industry benchmark in low power design.
