Apollo4 SoC EVB

Block Diagram for the Ultra-Low Power Apollo4 SoC

More Information

With up to 192 MHz clock frequency enabled by Ambiq's turboSPOT®, Apollo4 can achieve power efficiency as low as 5 µA/MHz when executing from SRAM and MRAM with cache. Coupled with up to 2MB of MRAM and 1.8MB of SRAM, the Apollo4 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 multi-bit SPI and eMMC interfaces.
Apollo4 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.

Apollo4 enables manufacturers to create leading-edge endpoint devices leveraging the unique SPOT platform with Ambiq’s easy-to-use, rich peripheral set.
