Enter to Win

Alif Semiconductor is revolutionizing the way developers create products using secure AI/ML-enabled 32-bit microcontrollers.

Alif Semiconductor’s microcontrollers and fusion processors are architected to provide:

Image

Unrivaled Battery Life

Longer product life on a smaller battery.

Image

Alif’s unique power architecture includes aiPM technology, a system that autonomously powers on only what is needed when needed, to give you battery life previously unheard of.

Image

Scalable Performance

Single to multi-core performance for any workload.

Image

Our processors scale seamlessly from single core to multi-core, giving you the freedom to reuse the same software across a wide spectrum of products. Ample memory, power management, security, graphics, imaging, and AI/ML, are all on-die, allowing for a true single-chip IoT design.

Image

Multilayered Security

Protection at every part of the device life cycle.

Image

Strong security is fundamental for connected devices. Our solution protects the device, data, and your customers throughout the full product life cycle by providing a strong Root of Trust, a separate isolated secure subsystem, identity protection, cryptographic services for user data, over the air updates, and fine-grained run-time security settings—all with minimal application overhead.

Image

HW Accelerated AI

At least 40X faster than conventional MCUs.

Image

All products offer hardware AI Acceleration with one or more dedicated Ethos-U55 Neural Processing Units, so you don’t have to sacrifice power or performance for AI workloads.

Always-on AI on solar power? AI pioneer MountAIn shows how it is done with an Ensemble MCU

What’s needed is human-like sensory intelligence – but without the humans. And that’s what Grenoble, France-based MountAIn has created with its AI end-to-end infrastructure. MountAIn’s technology is already in use: since July 2024, a successful pilot in the south of France has been monitoring for potential wildfires, using an array of AI-enabled smart cameras to detect smoke and trigger real-time alerts before fires escalate.

Alif Semiconductor elevates generative AI at the edge with new support for ExecuTorch Runtime in its Ensemble MCUs

San Francisco, CA, October 30, 2025 – Alif Semiconductor®, the leading global supplier of secure, connected, power efficient Artificial Intelligence and Machine Learning (AI/ML) microcontrollers (MCUs) and fusion processors, today announced that developers can now use the ExecuTorch Runtime, a quantization extension of the popular PyTorch ML framework, for AI applications built to run on

Support for ExecuTorch on Alif’s Ensemble MCUs brings PyTorch to the embedded edge

Until now, developers who use PyTorch for model training could not easily deploy them directly to resource-constrained edge devices – as the models which the PyTorch framework spits out are data-heavy and require some serious compute power to run. That’s fine for the cloud: not so good for edge AI.

PyTorch Conference 2025

We’re excited to join Arm next week at the PyTorch Conference 2025 — October 22–23 at Moscone West in San Francisco — the world’s premier event dedicated to the framework powering today’s most groundbreaking AI innovations.

Together, Alif Semiconductor and Arm will demonstrate how ExecuTorch runs on Alif’s Ensemble E8 fusion processor, enabling advanced generative AI and speech models to operate entirely on-device.

As the industry gathers to explore AI from bare metal to the application layer, our collaboration showcases how cutting-edge frameworks like PyTorch and ExecuTorch are driving a new era of efficient, ethical, and scalable edge intelligence.
