Murata has developed a 3rd generation of MEMS (Micro-Electro-Mechanical Systems) 4DoF (four-degrees-of-freedom) and 5DoF (five-degrees-of-freedom) inertial sensors that realize high-performance for safety critical automotive applications. The SCC3000 series components combine a high-performance angular rate and accelerometer sensor components. It consists of versions of an X-axis, Z-axis and XZ-axis angular rate sensors and a 3-axis accelerometer sensor based on Murata's proven capacitive 3D MEMS technology.
The SCC3000 components enable cost effective realization of ESC (Electronic Stability Control) product family of both standard and high-specification ESC with additional features. Pin-to-pin compatibility, together with the common SPI interface throughout the component family reduces the engineering effort at the system supplier level strengthening system robustness at the same time.
The SCC3000 series is designed, manufactured and tested to meet the requirements for high stability, reliability and quality. This component has extremely stable output over wide range of temperature, humidity and vibration conditions. Modern electrified drivetrains require new technology for brake actuation, as vacuum from internal combustion engine is not available. Sensor in the SCC3000 series has been designed to meet the new shock and vibration requirements coming from integrated brake systems enabling most cost & size effective ESC functionality in modern electrified vehicle architecture.
The product is qualified according to the AEC-Q100 standard, includes several advanced self-diagnostic features and is fully ASIL-D (Automotive Safety Integrity Level) compliant. The SCC3000 sensor series features extensive failsafe functions and error bits for diagnostics. These include internal reference signal monitoring, checksum techniques for verifying communication, and signal saturation/over range detection. The unique diagnostic feature of Murata's 3-axis accelerometer is the continuously operating self-test function which monitors the sensor during measurement. This patented self-test function verifies the proper operation of entire signal chain from MEMS sensor movement to signal conditioning circuitry for every measurement cycle.
- ISO26262 compliant for systems up to ASIL-D

- ±300°/s angular rate measurement range for robust sensing in harsh environment
- ±6g acceleration measurement range
- ±15g auxiliary acceleration measurement range
- -40°C～+110°C operating temperature range (Contact to Murata if +125°C is needed)
- User selectable filter setting 13, 20, 46, 200, 300Hz
- 3.0V～3.6V supply voltage
- Extensive self-diagnostics features
- Qualified according to the AEC-Q100 standard
The SCC3000 series is Murata's latest offering to the new decade of active safety systems. ESC is a global application requiring a smaller, higher performance family of components supporting standard ESC, high-performance ESC, Electronic Parking Brake, Lane Keep Assistance, Dynamic Chassis Control and other application requirements. Higher performance ESC systems are required as Lane Keep Assistance and similar applications are becoming standard option in many markets. This places increasingly strict requirements on the ESC sensor performance and functional safety.
Typical applications include:
- Electronic Stability Control (ESC)
- Headlight alignment
- Roll Over and Roll Stability Control
- Dynamic Chassis Control
- Lane Keeping Assistance (LKA)
- Motion and navigation measurement
