Product specifications
The Apollo4 Blue Plus SoC is the 4th generation system processor solution built upon Ambiq’s proprietary Subthreshold Power-Optimized Technology (SPOT®) platform. The Apollo4 Blue Plus’s complete hardware and software solution enables the wireless battery-powered endpoint devices of tomorrow to achieve a higher level of intelligence without sacrificing battery life.
The Apollo4 Blue Plus includes a 32-bit Arm® Cortex®-M4 core with Floating Point Unit (FPU) and a Bluetooth® Low Energy 5.1 radio. There are two variants in BGA packages. The AMA4BKP-KBR is pin-compatible to the Apollo4 Blue AMA4BKK-KBR for easy migration.
The AMA4BKP-KXR includes a HexSPI interface for faster access to PSRAM or other external memory for richer graphics.
With up to 2MB of MRAM and 2.75MB of SRAM, the Apollo4 Blue Plus has more than enough compute and storage to handle complex algorithms and neural networks while displaying vibrant, crystal-clear, and smooth graphics. If additional memory is required, external memory is supported through Ambiq’s high bandwidth hexSPI and eMMC interfaces.
The Apollo4 Blue Plus is purpose-built to serve as both an application processor and a coprocessor for battery-powered endpoint devices, including smartwatches, children’s watches, fitness bands, animal trackers, far-field voice remotes, predictive health and maintenance, and the smart home.
Features
Purpose-built SoC
Innovate for a wide range of endpoint IoT devices with powerful processing capability using an Arm® Cortex®-M4F core and TurboSPOT high frequency operation. With ample memory, this platform is engineered to drive battery-powered graphics, audio solutions, and more.
Extreme Low Power Modes
Push the longevity of battery-operated devices with unprecedented power efficiency. Make the most of your power budget with our flexible, low-power sleep and deep sleep modes with selectable levels of RAM/cache retention.
Bluetooth Low Energy 5.1
Go wireless with Apollo4 Blue. Implement reliable, faster Bluetooth connectivity using our robust, power optimized Bluetooth Low Energy 5.1 radio. Easily track always-on devices with Bluetooth’s direction-finding Angle of Arrival (AOA) and Angle of Departure (AOD) features.
Superior Graphics and Display
Use our highly energy efficient 2/2.5D graphics accelerator to implement high quality graphics with support for vector graphics, antialiasing, and dithering. A MIPI DSI high-speed interface coupled with support for 32-bit color and 500x500 pixel resolution enables developers to create compelling Graphical User Interfaces (GUIs) for battery-operated IoT devices.
Always-on Audio
Experience truly always-on voice processing with an ultra-low power analog microphone and optimized noise cancelling algorithms for clear voice. Achieve multi-channel processing and high-fidelity digital audio with enhanced digital filtering and low power audio interfaces.
