Apollo1 Ultra-low power MCUWith the release of the Apollo1 MCU Ambiq Micro proved what ultra-low power design can accomplish. Since then the growing Apollo microcontroller family provides the lowest active and sleep mode power on the market. With Apollo MCUs, designers of next generation wearables and IoT devices can take their innovative products to the next level by increasing battery life, adding more intelligent sensor processing, and fitting into smaller form factors.
