Syntiant makes low-power processors and software that let devices analyze sound, movement, images and other sensor inputs locally, rather than sending every decision to the cloud. Its core products are Neural Decision Processors (NDPs) for battery-powered and power-constrained devices, alongside modules and development hardware. The company has shipped more than 20 million NDPs, according to its 2022 milestone, and has continued expanding through new products, acquisitions and manufacturing investment.
What Syntiant makes
Syntiant describes itself as a semiconductor and software company focused on “Physical AI”: sensing and neural inference performed on a device so it can perceive and respond to real-world inputs. Its chips are designed for always-on or frequently used tasks where power consumption matters, including detecting a wake word, recognizing an acoustic event, noticing motion or identifying a person in a camera’s field of view.
This is edge AI: computation takes place near the sensor, often inside the product itself, instead of relying on a cloud service for each inference. Local processing can reduce dependence on a network round trip and may help a product respond quickly or keep some sensor data on-device. It does not mean every task is offline or that a device never communicates with a cloud service; those choices depend on the product maker’s design.
Syntiant sells components and developer platforms rather than a consumer gadget line under its own name. Its processors are aimed at products such as earbuds, hearing aids, smart-home devices, cameras, vehicles and industrial equipment.

How the NDP products differ
The NDP family covers audio, speech, sensor fusion and, in newer products, vision. The descriptions and performance figures below are Syntiant’s own product positioning; they are not independent comparisons under a shared test method.
| Product | Primary focus | What Syntiant specifies |
|---|---|---|
| NDP120 | Always-on speech and sensor fusion | Syntiant says it delivers 25 times the tensor throughput of its earlier Core 1 NDP100/NDP101 generation. It supports CNN, RNN and fully connected networks and includes an Arm Cortex-M0, HiFi 3 DSP, and SDK/TDK support. |
| NDP200 | Always-on vision, speech and sensor processing | Syntiant says vision inference can run below 1 mW. Listed tasks include person presence, object classification, wake words, motion tracking, acoustic-event classification and multi-sensor fusion. |
| NDP250 | Higher-performance edge inference | Syntiant positions it as a newer processor and claims a fivefold machine-learning performance increase over the NDP120/NDP200. The company’s stated comparison is not an independent benchmark. |
Use cases vary by chip and implementation. Syntiant lists NDP120 applications ranging from phones, earbuds and hearing aids to PCs, smart-home products, IoT endpoints, AR/VR, media streamers and vehicles. A chip’s presence in a product category does not establish that every listed product is available or uses that chip.

Why local inference matters in a product
For an engineer choosing an edge-AI processor, the relevant question is not simply whether a chip can run a model. The design has to meet a power budget, process the required sensor data and fit into a system that can be manufactured and supported.
- Power and battery life: Syntiant emphasizes always-on inference at very low power. The effect on a finished product’s battery life depends on the full system, including sensors, radio use, host processor and workload.
- Modality: The NDP portfolio spans speech and audio, motion and other sensors, and vision. A product’s sensor combination and model determine which inputs it can actually interpret.
- Latency and connectivity: Local inference can avoid waiting for a cloud round trip for supported tasks. A product may still need connectivity for other features, updates or services.
- Integration and development: SDK/TDK support, interfaces, host processors and partner modules affect the work needed to move from a chip evaluation to a finished device.
- Performance per watt: Syntiant’s stated 25-times and five-times performance comparisons can help identify its positioning, but should be treated as vendor claims rather than directly comparable independent results.
Developer hardware and integration options
RASynBoard for prototyping
The RASynBoard, developed with Avnet and Renesas, combines an NDP120 with a Renesas RA6M4 host microcontroller and a DA16600 Wi-Fi/Bluetooth module. It is an edge-AI development board for engineers prototyping low-power audio and sensor applications. The board’s documented existence does not establish current stock, pricing or availability in a particular country.
Murata Type2DA for compact integration
Murata’s Type2DA is a compact multi-chip module that integrates a Syntiant NDP102 with an MCU, crystal oscillator, LDO and flash memory. It is positioned for edge-AI audio and sensor applications, providing a module path rather than a general-purpose development board.
Sensor combinations
Syntiant also describes combinations with PixArt image sensors. Such partnerships illustrate the broader system approach: an edge-AI design depends on sensors, processing, software and host-device integration, not just the inference chip.

Is Syntiant an established company or an experiment?
Syntiant was founded in 2017. Its company timeline records the NDP100/NDP101 launch in 2019, more than one million processors shipped in 2020 and more than 20 million NDPs shipped in 2022. The 20-million figure is a company-reported milestone that groups NDP devices and AI software models; it is not a current annual shipment figure.
Later milestones point to expansion in both technology and business scope. Syntiant’s SEC-filed business disclosure records its 2022 acquisition of Pilot AI Labs to strengthen computer-vision models, and its 2024 acquisition of Knowles’ CMM business to build a broader sensor platform. The company timeline also lists NDP115 in 2023 and NDP250 in 2024.

The SEC disclosure records a first AI smart-glasses design win and transformer-based vision work in 2025. In 2026, it records a Penang manufacturing facility and acquisitions of Orosound and AudioSourceRE. These events indicate strategic expansion, but a design win is not the same as a disclosed product shipment or a guarantee of commercial success.
Market opportunity: a forecast, not a guarantee
A Syntiant SEC prospectus filed in 2026 estimates the Physical AI processor market at approximately $4.1 billion in 2025 and $16.7 billion in 2030, implying a 32% compound annual growth rate. The prospectus attributes the estimate to Gartner. These are market estimates cited by the company, not Syntiant revenue, a measure of its market share or a guaranteed outcome.
The same 2026 SEC disclosure gives approximately 1.6 billion units of annual sensor manufacturing capacity after the Penang facility. That is a capacity figure, not evidence that the facility will produce that volume or that Syntiant has secured demand for it.
What the company’s trajectory means for a reader
For a product developer, Syntiant is a supplier to evaluate when an application needs low-power, on-device inference across audio or sensors, with vision capability in parts of the portfolio. The board and module examples show routes to prototype or integrate its technology, while its product claims provide starting points for technical comparison—not substitutes for checking workload fit, toolchain support and system-level power.
