Product specifications
Apollo3 Blue Plus - Ultra-Low Power System on Chip with integrated Bluetooth Low Energy.
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 batterypowered 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®-M4F processor with Floating Point Unit and TurboSPOT® increasing the computational capabilities ofthe Arm® Cortex®-M4F core to 96 MHz while lowering the active power consumption to < 6uA/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 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.
The Apollo3 Blue Plus also forms the core of Ambiq's Voice-on-SPOT® reference platform making it the perfect device for always-on voice assistant integration and command recognition to battery-powered devices.
The Apollo3 Blue Plus provides a dedicated second core for the ultra-low power Bluetooth Low Eneregy 5 connectivity platform providing superior RF throughput and leaving plenty of resources available for user applications.
The Apollo3 Blue Plus adds two additional MSPI modules (3 total), and increases the external memory execute-in-place (XiP) aperture from 64MB to 96MB (32MB/ MSPI instance). Additionally, internal flash increases from IMB to 2MB, SRAM from 384KB to 768KB (TCM size remains at 64KB) and the GPIO count increases from 50 to 74.
