Platforms – Ambiq

Ambiq Apollo4 Blue SoC

 The 4th generation  Apollo4 Blue System-on-Chip (SoC) family is built upon Ambiq’s proprietary Subthreshold Power Optimized (SPOT) platform.  With its complete hardware and software framework, it enables battery-powered endpoint devices of a higher level of intelligence without sacrificing battery life. 

The Apollo4 Blue SoC comes with a Floating Point Unit (FPU), 2MB of MRAM and 1.8MB of SRAM, giving targeted endpoint devices more than enough compute and storage in handling complex algorithms and neural networks while displaying vibrant, crystal-clear, and smooth graphics.

The Apollo4 Blue SoC is also embedded with Bluetooth Low Energy 5 radio that supports Angle of Arrival (AoA) and Angle of  Departure (AoD) for always-on applications.
