STMicroelectronics today introduced the ISM6HG256X, a compact 2.5 mm × 3 mm MEMS sensor that combines a ±16 g low‑g accelerometer, a ±256 g high‑g accelerometer, and a precision gyroscope in a single package. Embedded in the chip is a machine‑learning core, self‑configuration logic, and sensor‑fusion algorithms that enable real‑time event detection and context‑aware sensing without off‑chip processing.
The dual‑range design eliminates the need for separate low‑ and high‑g sensors, cutting system complexity, power consumption, and cost for customers. The ISM6HG256X is engineered for a broad range of industrial IoT applications—including asset tracking, worker‑safety wearables, condition monitoring, robotics, factory automation, and black‑box event recording—where both subtle motions and high‑impact events must be captured in the same device.
This launch strengthens ST’s MEMS portfolio and supports its strategy to deliver edge‑AI‑enabled solutions for the growing industrial IoT market. The sensor is part of a 10‑year longevity program that guarantees availability, a key differentiator for industrial customers with long‑term product roadmaps. The announcement follows ST’s July 2025 acquisition of NXP’s MEMS business for $950 million, which expands the company’s high‑performance sensor capabilities, and the October 2025 launch of a new family of 5 MP CMOS image sensors, underscoring ST’s broader push into smart‑sensor markets.
Industry analysts project the smart‑sensor market to grow from $49.6 billion in 2025 to $187.2 billion by 2032, driven by Industry 4.0 and 5.0 initiatives that demand autonomous, adaptive processes. ST’s edge‑AI focus—processing data on the sensor itself—reduces latency, enhances privacy, and improves scalability, positioning the company ahead of competitors such as Bosch Sensortec and Texas Instruments. The dual‑range capability and 10‑year guarantee further strengthen ST’s competitive edge in industrial applications where reliability and cost efficiency are paramount.
ST is providing developer support through an expansion board (X‑NUCLEO‑IKS5A1) and software libraries (X‑CUBE‑MEMS1) that simplify sensor‑fusion, context awareness, and calibration. These tools accelerate time‑to‑market for customers integrating the ISM6HG256X into their products.
The ISM6HG256X is available now with a starting price of $4.27 for a 1,000‑unit order, and the 10‑year longevity program ensures that customers can rely on the sensor for the long term without the risk of obsolescence.
