Apollo3 Blue Plus EVB - Ultra-Low Power System on Chip
The Apollo SoC Family is an ultra-low power, highly integrated System on Chip platform based on Ambiq's patented Subthreshold Power Optimized Technology (SPOT®) and designed for battery-powered and portable, mobile devices.
The Apollo3 Blue Plus 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 less than 6µA/ 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 Plus SoC 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. To increase design flexibility and enable connections to the phone and cloud, the Apollo3 Blue Plus provides a dedicated second core for ultra-low power Bluetooth Low Energy 5 connectivity, providing superior RF throughput and leaving plenty of resources available for user applications. With unprecedented energy efficiency and PDM microphone inputs, the Apollo3 Blue Plus 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 to battery-powered devices.
The Apollo3 Blue Plus feature two additional MSPI modules (3 total), and increases the external memory execute-in-place (XiP) aperture from 64MB to 96MB (32MB/ MSPI instance) compared to the Apollo3 Blue. Additionally, internal flash increases from 1MB to 2MB, SRAM from 384KB to 768KB (TCM size remains at 64KB) and the GPIO count increases from 50 to 74.
