Combined gyro and accelerometer sensor family with revolutionary automotive solution

Murata expands its range of innovative Six Degrees-of-Freedom devices by introducing the SCH1633-D01. The MEMS-based sensor moves the benchmark for performance, system integration, and total cost optimisation. It is designed for various automotive applications, including AD, ADAS, inertial navigation, vehicle stability control, and camera or headlight alignment.

The SCH1633-D01 is a single-package solution optimised for zonal architecture where all required subsystems, like GNSS integration, chassis control, and vehicle attitude sensing (camera and headlight alignment), can utilise its measurements. It is targeted for deployment in the central vehicle IMU, providing a high-quality signal for all subsystems within the vehicle, even in the toughest environments. This integration helps to reduce system complexity and provides a much-needed opportunity for cost optimisation.

The device is packaged in a unique 24-pin SOIC housing and uses the SafeSPI 2.0 interface with an up to 20-bit data frame for an extremely smooth and high-resolution output. The component supports various system-level time synchronisation features, allowing the device’s output to be easily harnessed across the whole vehicle. Also, the extensive self-diagnostics features utilise over 200 monitoring signals to ensure the output is always trustworthy.

The SCH1633-D01 is designed to deliver a high-quality output, even in harsh temperature conditions. It features AEC-Q100 grade 1 qualification to guarantee reliable use throughout the whole component lifetime and is ISO26262 compliant with ASIL-B+ rating (up to ASIL-D via system integration) for exceptional built-in safety.
