Ambiq Apollo330 Plus Ultra-Low Power Systems-on-Chips
Ambiq Apollo330 Plus Ultra-Low Power Systems-on-Chips (SoC) are engineered to deliver high‑performance edge and Artificial Intelligence (AI) computing while dramatically reducing power consumption. The Ambiq Apollo330 Plus SoCs are ideal for next‑generation battery‑powered and always‑on devices. Built on Ambiq’s Subthreshold Power Optimized Technology (SPOT®), the Apollo330 Plus family integrates an Arm® Cortex®‑M55 processor (running up to 250 MHz with Helium™ vector extensions) to accelerate AI inferencing at the edge with exceptional efficiency. These devices also feature a dedicated Arm Cortex‑M4F network processor for low‑power wireless communication, with variants supporting BLUETOOTH® Low Energy, Thread, and Matter. This architectural combination allows devices to perform more complex on‑device AI tasks, maintain long battery life, and enable real‑time responsiveness in edge applications.
The Apollo330 Plus SoC series offers enhanced memory performance with over 2MB of system RAM, 2MB of embedded non‑volatile memory, sizable instruction and data caches, and a rich suite of peripherals, including advanced sensor interfaces and an ultra‑low‑power digital microphone for truly always‑on voice capabilities. Designed for body‑worn, ambient, smart home, healthcare, and industrial edge environments, the Apollo330 Plus series provides robust hardware‑based security through secureSPOT® and TrustZone® technologies, enabling secure boot, firmware updates, and data protection. Overall, the Apollo330 Plus platform empowers manufacturers to build intelligent, responsive, and energy‑efficient products that leverage local AI processing without relying heavily on the cloud.
