The Apollo family of microcontrollers from Ambiq Micro represents a quantum leap forward in the low-power MCU world. Power sensitive applications today are not looking for incremental reductions in energy consumption - they need revolutionary advances and the Apollo MCUs deliver. These highly-integrated microcontrollers offer industry-leading power numbers in BOTH active modes and sleep modes. Additionally, they offer the performance of an ARM Cortex-M4F core at power levels that are even lower than competing ARM Cortex- M0+ solutions. Unrivaled power savings combined with a high-performance processing engine make the Apollo MCUs an ideal solution for battery-powered devices and other power-sensitive applications.
