It consists of a low-g 3-axis accelerometer with two angular rate sensor options of either X or Z-axis detection, together with a 32-bit digital SPI interface. The sensor has a software selectable 10 or 60 Hz low pass filter that can be configured via SPI. Gyro range is ±125 degrees per second with sensitivity of 50 LSB per degree per second. Typical accelerometer offset temperature drift is ±6 mg for the 2g sensor and ±12mg for the 6g version. Gyroscope offset temperature drift is typically in the range ±0.5°/s for the 125°/sec X & Z -axis product versions. The gyroscope has a typical offset short-term bias stability of 1°/hour for the 125°/sec X-axis device and 2°/hour for the 125°/sec Z-axis product. A combined sensor with a gyro having a range of up to 300 degrees per second is also available.
Murata positions the SCC2000 series product family as providing a complete product platform for acceleration and angular rate detection in all three sensing axis directions. With the newly introduced Z axis gyroscope version designers can implement a 6-DOF (degrees of freedom) sensor solution on one application PCB.
The SCC2000 devices are available in a 24-pin premoulded plastic RoHS compliant SOIC housing suitable for SMD mounting, measuring 15.00 x 12.10 x 4.35 mm. The combined sensor is compliant to the ISO26262 automotive safety standard and the AEC-Q100 stress test qualification requirements for electronic components used in automotive applications. It is a suitable platform for use in both active and passive safety designs in automotive applications such as hill start assistance (HSA), active steering, and adaptive cruise control for advanced driver assistance systems (ADAS). With a robust construction and the sensor's high performance the SCC2000 series is also suitable for demanding environments such as agricultural, construction and other heavy machinery applications.
