Product specifications
Ambiq®, a leader in low power System-on-Chip (SoC) design, introduces the Apollo4 Plus SoC, bringing enhanced graphics performance, additional on-chip memory and increased memory performance to the Apollo4 SoC product family. Apollo4 Plus enables designers of next generation wearables and smart devices to deliver even more stunning user interface (UI) effects and overall user experience to take their innovative products to the next level.
The Apollo4 Plus SoC is built upon Ambiq’s proprietary Subthreshold Power-Optimized Technology (SPOT®) platform. The Apollo4 Plus complete hardware and software solution enables the battery-powered endpoint devices of tomorrow to achieve a higher level of intelligence without sacrificing battery life. The Apollo4 Plus is available in BGA package option.
With up to 2MB of MRAM and 2.75MB of SRAM, the Apollo4 Plus has more than enough compute power 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 multi-bit SPI and eMMC interfaces.
The Apollo4 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.
