Problem
Developers of battery‑operated IoT and edge devices need microcontrollers that can run heavy AI/ML workloads, support multiple wireless protocols, and provide strong security while consuming minimal power. Traditional MCUs lack on‑chip AI accelerators and require external components, leading to larger footprints, higher power draw, and longer time‑to‑market.
Solution
Alif Semiconductor offers the Ensemble and Balletto families of Arm‑based 32‑bit microcontrollers that integrate high‑performance Cortex‑M55 and Cortex‑A32 cores, dedicated Ethos‑U55 neural processing units, and extensive on‑die memory, peripherals, and security features. Their aiPM power‑management system powers only the required domains, delivering ultra‑low deep‑sleep currents (as low as 80 µA) and extending battery life for years. Integrated BLE 5.3, 802.15.4, Ethernet, graphics, audio, and sensor interfaces eliminate the need for external chips, enabling compact, single‑chip designs. Hardware AI acceleration provides 40‑plus times faster inference than conventional MCUs, allowing real‑time vision, audio, and sensor‑fusion workloads directly on the device.
Target Audience
Primary customers are hardware designers and OEMs building battery‑powered edge products such as wearables, smart cameras, audio earbuds, medical devices, and industrial IoT sensors that require on‑device AI, connectivity, and stringent security.
