Alif Semiconductor

Alif Semiconductor is a supplier of 32-bit AI/ML-enabled microcontrollers (MCUs) and fusion processors. Founded in 2019, the company's flagship product line is the Ensemble family, which ranges from single-core microcontrollers to multi-core fusion processors. The Ensemble devices combine Arm Cortex-M55 MCU cores, Cortex-A32 microprocessor cores, and Ethos-U55 microNPUs for AI/ML acceleration. Alif's processors are designed to be energy efficient, utilizing the company's Autonomous Intelligent Power Management (aiPM) technology that powers on only what's needed, when needed. This allows for extended battery life in applications like wearables, security cameras, and IoT devices.

The Ensemble family includes the E1, E3, and E7 series, with the E1C serving as an entry-level option. These processors offer high AI performance combined with ultra-low power consumption. For instance, the Balletto family, announced in April 2024, is claimed to be the world's first Bluetooth Low Energy wireless microcontroller featuring hardware optimization for AI/ML workloads. It can perform up to 46 GOPS (Giga Operations Per Second) and is designed for applications such as true wireless stereo earbuds and lifestyle wristbands.

Alif's processors incorporate advanced security features, including a Secure Enclave with its own resources and a configurable secure firewall structure. The company's security architecture aims to counter and resist malicious attacks in deployed edge products. Alif Semiconductor's products are designed to enable seamless integration of technology for everyday life by focusing on low-power techniques, functional integration, accelerated AI and ML edge processing, high security, wireless connectivity, and operating system diversity.

Key customers and partnerships

Alif Semiconductor has collaborated with several companies in the semiconductor and technology sectors. In November 2022, Alif partnered with onsemi to create a camera reference design for low-power applications using machine vision. This collaboration aimed to address challenges in implementing imaging products with long battery life and localized AI/ML capabilities.

In January 2024, Alif Semiconductor and Telit Cinterion unveiled the Vision AppKit, described as the world's smartest and most efficient connected camera reference design. This kit combines Telit Cinterion's wireless technology with Alif's Ensemble E3 series MCU for on-device AI use cases like face and object detection and image classification.

Alif has also worked with Plumerai, a creator of edge AI solutions, to deploy what they claim is the world's most precise person detection on the Ensemble platform. This collaboration demonstrated the potential for accurate computer vision AI in a small form factor that can run on battery power for extended periods.
