Murata Manufacturing has announced the SCH1633-D05, a six-degrees-of-freedom (6DoF) inertial measurement unit (IMU) that expands the SCH1600 sensor family. The device integrates a XYZ-axis gyroscope and XYZ-axis accelerometer. It is designed for use in Automated Driving (AD), Advanced Driver Assistance Systems (ADAS), inertial navigation, vehicle stability control, dynamic and headlight leveling, and humanoid robotics. Mass production is scheduled to begin in June 2026, with samples currently available.
The SCH1633-D05 addresses requirements of the shift toward zonal architecture in automotive electronics, where IMUs are mounted directly onto Electronic Control Units (ECUs). This requires high component-level performance since post-assembly calibration is difficult. The sensor combines Murata’s 3D MEMS process with the latest ASIC design to deliver ceramic-package-level temperature performance in a plastic SOIC package. The package includes integrated EMC shielding and a low profile for space-constrained ECU environments.
Extended factory calibration compensates for sensor behavior across the full operating temperature range, eliminating the need for customer-side temperature calibration. Total gyroscope offset performance is below 0.15 °/s across all axes.
The IMU provides best-in-class bias instability and noise performance. The gyroscope has a measurement range of ±300 °/s. The accelerometer has a measurement range of ±80 m/s², with an auxiliary channel supporting up to ±260 m/s² dynamic range. It offers 20-bit data resolution. The device incorporates over 200 internal monitoring signals to support functional safety requirements for systems developed to ISO 26262 standards.
The SCH1633-D05 enables a single high-performance IMU to serve multiple vehicle functions, reducing PCB area, sensor count, and cabling. It is housed in a lead-free, halogen-free SOIC package compliant with ELV, RoHS, and China RoHS.
