More Information

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.
