Ambiq Micro AMA3B2KK-KBR
ARM Cortex-M4, 48 MHz, 1 MB ROM, 768 kB RAM
The Apollo MCU family is an ultra-low power, highly integrated microcontroller designed for battery powered devices including wearable electronics, activity and fitness monitors, and wireless sensors. By combining ultra-low power sensor conversion electronics with the powerful ARM Cortex-M4F processor, the Apollo MCU enables complex sensor processing tasks to be completed with unprecedented battery life. Apollo MCUs take full advantage of Ambiq Micro's patented SPOT (Subthreshold Power Optimized Technology) platform, setting a new industry benchmark 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.
