STMicroelectronics has introduced a new family of automotive MEMS safety sensors, marking the first mass-market products launched since the company completed its acquisition of NXP’s automotive and industrial MEMS sensors business earlier this year.

The announcement highlights how ST is expanding its position in automotive sensing as vehicle manufacturers seek to deploy advanced safety and driver-assistance capabilities across broader vehicle segments rather than limiting them to premium models.

The new devices combine multi-axis accelerometers and gyroscopes within a single package, providing a common sensing platform for applications ranging from crash detection and rollover sensing to airbag deployment, vehicle stability control, and radar beam stabilization.

Strengthening Automotive Safety Platforms

For automotive OEMs and Tier-1 suppliers, the sensors are designed to support both active and passive safety architectures while meeting automotive requirements for quality, reliability, and functional safety.

According to ST, the sensors integrate accelerometer and gyroscope functions in ISO 26262-compliant devices with internal diagnostics and support for SafeSPI, a safety-focused serial communication interface that enables independent monitoring of sensor data.

“As a cohesive sensor set suited to multiple safety functions, these devices simplify system architecture, accelerate development, and increase flexibility to scale features and performance,” said Simone Ferri, Executive Vice President of ST’s MEMS Sub-Group.

Ferri added that the products are intended to support broader deployment of automotive safety systems while leveraging ST’s long-term supply commitment and global support network.

Positioned for Growing ADAS Demand

The launch comes as demand for inertial sensing technologies increases alongside the expansion of advanced driver-assistance systems.

“Thanks to ADAS, inertial measurement units (IMUs) are expected to grow at 17.7% CAGR (2025-30),” said Nora Houlihan, Senior Research Analyst at Omdia. “As automotive manufacturers approach higher levels of autonomy there will be a significant increase in IMU-powered MEMS sensors for acceleration and motion detection.”

The product family includes four sensor variants configured for different combinations of angular-rate and acceleration measurements. The devices support multiple sensing ranges and filtering options while maintaining operation across automotive temperature requirements from −40°C to +105°C.

From Acquisition to Product Execution

Strategically, the launch serves as an early indication of how ST plans to leverage technology and market opportunities gained through the NXP MEMS acquisition.

Beyond the technical specifications, the company is emphasizing long-term program support. ST said it will guarantee product availability for at least 15 years, a factor intended to help automotive customers reduce redesign risks associated with long vehicle development cycles.

The four sensors are already in production and are supplied in 24-pin QFN packages designed to meet automotive optical inspection requirements.

First Products Since NXP MEMS Acquisition

The launch is notable because it represents the first mass-market automotive sensor family introduced since STMicroelectronics acquired NXP’s automotive and industrial MEMS sensors business in early 2026. ST said the acquisition was completed to expand its MEMS sensor capabilities, with the new safety-focused devices marking the first commercial products introduced following the transaction.
