Product specifications

Apollo4 Lite maintains feature-rich capability and optimizes memory and peripherals to balance the Apollo4 product family with a lightweight solution. It is conveniently pin-compatible to its superset variant, Apollo4 Plus, providing developers the optimum flexibility to innovate with smooth, vibrant graphics in their next generation wearables and smart IoT devices.
The Apollo4 Lite SoC is built upon Ambiq’s proprietary Subthreshold Power-Optimized Technology (SPOT®) platform. The Apollo4 Lite 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 Lite includes a 32-bit Arm® Cortex®-M4 core with Floating Point Unit embedded in a BGA package.
With 2MB of MRAM and 1.4MB of SRAM, the Apollo4 Lite has optimal compute and storage to process 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 Lite is purpose-built to serve as both an application processor and a coprocessor for battery-powered endpoint devices, including smartwatches, fitness bands, animal trackers, voice activated remotes, digital health products, industrial maintenance, and smart home IoT devices.
