Summary of DUAL-AXIS GYROSCOPE AND 3-AXIS ACCELEROMETER MEMS SENSOR WITH DIGITAL SPI INTERFACE FOR AUTOMOTIVE APPLICATIONS
Murata's SCC300 series are 3rd-generation MEMS 4DoF and 5DoF inertial sensors combining high-performance angular rate and 3-axis accelerometer components for safety-critical automotive applications. They offer X-, Z-, and XZ-axis gyros plus a 3-axis accelerometer, high reliability across temperature, humidity, and vibration, and meet shock/vibration requirements for integrated brake and ESC systems. The series targets cost-effective ESC solutions with pin-to-pin compatibility, common SPI interface, ISO26262 ASIL-D compliance, wide measurement ranges, selectable filters, and automotive-grade operating conditions.
Parts used in the SCC300 series:
- X-axis angular rate sensor
- Z-axis angular rate sensor
- XZ-axis angular rate sensor
- 3-axis accelerometer sensor
- On-chip digital SPI interface
Murata has introduced the SCC300 series components that combine high-performance angular rate and accelerometer sensor components. The SCC300 is the 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 new device consists of versions of an X-axis, Z-axis, and XZ-axis angular rate sensor and a 3-axis accelerometer sensor.
The SCC300 series is designed, manufactured, and tested to deliver reliability, quality, and extremely stable output over a wide range of temperature, humidity, and vibration conditions. The sensor in the device is designed to meet the new shock and vibration requirements coming from integrated brake systems for more cost-effective and size effective ESC (Electronic Stability Control) functionality in modern electrified vehicle architecture.
The SCC3000 series provides a cost-effective realization of ESC product family for both standard and high-specification ESC with additional features. Pin-to-Pin Compatability combined with common SPI-interface in the components to reduce the engineering effort at the system supplier level, this strengthens the system robustness.
