Murata SCA2100 2-Axis MEMS Accelerometer | AEC-Q100 Automotive-Grade High-Precision Tilt and Motion Monitoring

The Murata SCA2100 series 2-axis digital accelerometer continues to garner attention in the automotive and industrial automation markets. Built upon the proven 3D MEMS capacitive sensing technology inherited from VTI, the SCA2100 is an AEC-Q100 qualified automotive-grade 2-axis accelerometer. Featuring high stability, wide operating temperature range and built-in self-diagnosis functions, it targets safety-critical applications including automotive systems, heavy construction machinery and industrial attitude measurement scenarios, delivering highly reliable solutions for tilt, vibration and acceleration data acquisition.

The SCA2100 has a fixed measurement range of ±2g, outputs data via the SPI digital interface with a sensitivity of 900 LSB/g and a typical bandwidth of 45 Hz. It adopts DFL surface-mount package with dimensions of 7.0×8.6×3.3 mm, supports mass-production SMT soldering and complies with RoHS environmental standards. Its operating temperature ranges from -40℃ to +125℃. It exhibits minimal output drift under harsh working conditions such as extreme temperatures, intense vibration and high humidity. Equipped with an enhanced on-chip self-diagnosis mechanism, it can perform real-time sensor status checks to meet fault detection requirements for safety-related systems. Pin-to-pin and SPI protocol compatibility with Murata’s SCA3100 and other digital accelerometer product lines facilitates modular hardware design and product iteration.

In practical deployment, the SCA2100 is a preferred component for automotive safety systems. It is widely applied in Electronic Stability Control (ESC), Hill Start Assist (HSA), Electronic Parking Brake (EPB) and rollover detection as well as vehicle suspension attitude monitoring. It is also suitable for industrial scenarios such as construction machinery, heavy-duty vehicles, industrial inclinometers, structural vibration monitoring and high-precision inertial measurement equipment.

Applications:

Anti-lock Braking System (ABS)

Hill Start Assist (HSA)

Anti-Roll Stability Control System (ARC)

Rollover Sensor (ROV)

Key Differentiator:

The SCA2100 is a 2-axis accelerometer without a gyroscope. It has a completely different positioning compared with consumer-grade 6-axis IMUs (BMI323, LSM6DSV, ICM42688). Optimized for automotive safety and long-term stability, it is not a consumer-grade attitude sensor. It is ideal for projects with strict mandatory requirements for reliability and fault diagnosis.

Industry insiders note that for safety-critical projects in automotive and construction machinery, conventional consumer-grade IMUs cannot meet AEC-Q100 and self-diagnosis specifications. The Murata SCA2100 addresses the demand for stable supply of 2-axis automotive-grade accelerometers and provides robust hardware support for tilt monitoring and vehicle motion sensing. The SCA2100 series is available with stable supply at present. Full datasheets, application notes and evaluation boards are available to support customers for rapid development.
