The company has introduced an expanded Apollo4 SoC portfolio, including the latest Apollo4 Plus and Apollo4 Blue Plus with Bluetooth Low Energy connectivity with enhanced graphics display capabilities and more robust security features to better protect power-constrained IoT endpoint devices without compromising power efficiency.

“The future of IoT is in the intelligence of things that stay on and connected 24/7,” says Dan Cermak, VP of Architecture and Product Planning at Ambiq. “The latest product and feature additions to our Apollo4 SoC family demonstrate that battery-operated devices no longer have to compromise performance for power constraints.”

The Apollo4 Plus is the 4th generation system processor solution built upon the company’s proprietary Subthreshold Power-Optimized Technology (SPOT) platform, enabling new features while reducing devices’ overall system power consumption to extend their battery life. Embedded with the company’s megabytes of MRAM, SRAM, ultra-low power processors, solid software stacks, and up to 192 MHz operating frequency with TurboSPOT, says the company, the latest SoC to the Apollo4 family empowers more AI-capable operations, including data ingestion, pre-processing, inference, and actuation.

Equipped with an ultra-low power, end-to-end audio subsystem, the Apollo4 is designed to run compute complex algorithms required for precise voice recognition and higher fidelity voice capability needed for voice calls. Its integrated GPU and display controller, coupled with fast and efficient memory access, offer manufacturers the ability to differentiate their products with bigger and richer display user interfaces with vivid colors, high-resolution and smooth graphics. The company’s Secure by Design features allow OEMs to secure their products from the ground up when implementing SecureSPOT with tools to implement end-to-end security from the start.

The latest addition to the Apollo4 family provides enhanced graphics display and greater voice capabilities to serve as either an application processor or a coprocessor for battery-powered endpoint devices. The Apollo4 Plus is now in mass production, targeting smartwatches and smart bands, consumer medical devices, motion and tracking units, and the smart home of the 21st century.
