Apollo3 Blue Plus System-on-Chip Ambiq Apollo3 Blue Plus System-on-Chip offers ultra-low power in a highly integrated SoC platform based on Ambiq's patented Subthreshold Power Optimized Technology (SPOT®). The Apollo3 Blue Plus SoC provides a new standard in energy efficiency for battery-powered devices, implementing an integrated Arm® Cortex®-M4 processor with Floating Point Unit and turboSPOT®. These features boost the computational capabilities of the Arm Cortex-M4F core to 96MHz while lowering the active power consumption to <,6µA/MHz. Furthermore, this combination dramatically reduces energy consumption while allowing abundant application processing power to expand capability and extend life to battery-operated devices.
