Insights
TL;DR Product showcases Tower's charge-domain CMOS image sensor capability but lacks financial or volume details to assess near-term revenue impact.
Tower's role as the foundry partner for a high-speed, charge-domain imager highlights a differentiated process capability in CMOS image sensor and analog charge-domain integration. The 260k fps claim and embedded analog neuron layer are technical differentiators that could support design wins across industrial and edge markets. However, the release provides no information on production capacity, expected unit pricing, customer engagements, or margins, so investor impact is currently strategic rather than quantifiable.
TL;DR Cheetah HS's on-pixel analog neural layer and 260k fps capability are technically significant for ultra-high-speed, low-power edge vision applications.
The combination of charge-domain pixel processing with an integrated first-layer analog neural network can materially reduce BOM and system power by avoiding separate high-speed ADCs and interfaces. Programmable frame rates and an integrated LED driver (up to 40 mA) make the design versatile for inspection, motion analysis and embedded tracking. Actual system-level benefits will depend on downstream integration, algorithm compatibility with pulse-stream outputs, and volume economics.

AIStorm & Tower Semiconductor Introduce Cheetah HS, World’s First Up-to-260K FPS
AI-in-Imager Chip for Inspection, Robotics & Sports
Charge-domain imager with on-chip neural network, provides breakthrough slow-motion vision at a fraction of the
cost and power consumption of competing high-speed cameras
HOUSTON, Texas, and MIGDAL HAEMEK, Israel - August 12, 2025: AIStorm, the market leader in charge-domain solutions for edge AI, and Tower
Semiconductor (NASDAQ/TASE: TSEM), a leading foundry of high-value analog semiconductor solutions, today announced the availability of the Cheetah HS — a high-speed, 120×80-pixel imager with first-layer AI capability that captures up to 260,000
frames per second — 2,000 to 4,000 times faster than conventional CMOS sensors. The Cheetah HS architecture is made possible by Tower’s unique charge-domain imaging platform which is leveraged by AIStorm’s proprietary charge-domain-based analog AI
neurons.
By combining ultra-high-speed imaging with charge-domain AI, Cheetah HS slashes system power requirements and bill-of-materials cost for designers of robotics, drones, vibration- and
structure-health monitors, high-speed security and surveillance tracking systems, manufacturing and assembly lines, barcode readers, PCB-inspection equipment, biometric unlock systems, vehicle-speed detectors, and even golf-swing analyzers.
“Many consumer and industrial applications require ultra-slow-motion analysis of real-time events to analyze performance or detect anomalies. Such solutions are very costly, and our Cheetah HS
solution makes them affordable for a wide range of markets and end applications,” said David Schie, CEO of AIStorm. “Tower is a global leader in charge-domain global-shutter pixels, making them the ideal
partner for the development and production of such groundbreaking products.”
“We are very pleased to see the fruits of our long term, close collaboration with AIStorm on this unique breakthrough platform of analog charge-domain embedded AI technology,” said Dr. Avi Strum, SVP and GM of the Sensors and Displays BU at Tower Semiconductor. “Its inherent low-power, low-cost, and high-performance virtues will enable a family of affordable, high-volume products in the
near future.”

How it works
Traditional high-speed cameras utilize expensive high-speed data converters to capture data, which separates the AI input layer from the pixels, increasing the BOM cost and necessitating high-speed
connectors and interface components. Cheetah HS’s charge-domain architecture converts incoming photons to charge, computes the first neural-network layer in analog form, then outputs a pulse train that can be processed by downstream networks. The
capture rate is programmable, allowing lower frame rates with faster capture times (reducing the cost of processing) or faster frame rates for accurate measurements or slow-motion analysis.
Availability
Cheetah HS is available now in both chip form as well as full reference-camera systems [aistorm.ai/cheetah].
