More Information

The Apollo3 Blue SoC sets a new standard in energy efficiency for battery powered devices with an integrated Arm® Cortex®-M4 processor with Floating Point Unit and turboSPOT® increasing the computational capabilities of the Arm Cortex-M4F core to 96 MHz while lowering the active power consumption to < 6 μA/ MHz. This combination dramatically reduces energy consumption while still enabling abundant application processing power to add greater capability and extended life to battery operated devices.

The Apollo3 Blue brings several new features to Ambiq’s SPOT-based Apollo SoC Family including an integrated DMA engine, QSPI interface, and advanced stepper motor control for ultra-low power analog watch hand management.
With unprecedented energy efficiency and PDM microphone inputs, the Apollo3 Blue also forms the core of Ambiq’s Voice-on-SPOT® reference platform making it the perfect device for customers who want to add always-on voice assistant integration and command recognition to battery-powered devices. To increase design flexibility and enable connections to the phone and cloud, the Apollo3 Blue provides a dedicated second core for the ultra-low power Bluetooth Low Energy 5 connectivity platform providing superior RF throughput and leaving plenty of resources available for user applications.
