High-Stability MEMS Accelerometer Combined Gyroscope

Murata recently announced the SCC2000 series of combined accelerometer and gyroscope sensor devices aimed at use in tough environments, such as automotive and industrial applications. The series has best-in-class temperature dependency, shock sensitivity and bias stability characteristics, and consists of a low-g 3-axis accelerometer with two angular rate sensor options of either X or Z-axis detection combined with a -32 bit digital SPI interface.

In addition to the above-mentioned features, the sensor also 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°/s X & Z -axis product versions. The Gyroscope has a typical offset short-term bias stability of 1°/h for the 125°/s X-axis device and 2°/h for the 125°/s Z-axis product. A combined sensor with a gyro having a range of up to 300 degrees per second is also available on customer request.

The SCC2000 devices are available in a 24-pin pre-molded plastic RoHS compliant SOIC housing suitable for SMD mounting measuring 15.00 x 8.50 x 4.35 mm. The combined sensor is compliant with the internationally recognized ISO26262 automotive software safety standard and the AEC-Q100 stress test qualification requirements. It is an ideal 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 the most demanding environments such as agricultural, construction, and other heavy machinery applications.
