Doc.Nr. 82 1130 00 Data Shee t SCR1100-D02 SINGLE AXIS GYROSCOPE WITH DIGITAL SPI INTERFACE Features Applications 100 /s angular rate measurement range SCR1100-D02 is targeted to applications with high Angular rate measurement around X axis stability and tough environmental requirements. Typical applications are: Angular rate sensor exceptionally insensitive to mechanical vibrations and shocks Inertial Measurement Units (IMUs) for highly demanding environments Superior bias instability for MEMS gyroscopes Platform stabilization and control (<1/h) Digital SPI interfacing Motion analysis and control Roll over detection Enhanced self diagnostics features Small size 8.5 x 18.7 x 4.5 mm (w x l x h) Robotic control systems RoHS compliant robust packaging suitable for Guidance systems lead free soldering process and SMD mounting Navigation systems Proven capacitive 3D-MEMS technology Temperature range -40 C...+125 C General Description SCR1100-D02 is a single axis high performance gyroscope. It is part of Murata s high performance gyro family and it has the same gyro section as the combined gyro acceleration product SCC1300-D02. The sensor is based on Murata s proven capacitive 3D-MEMS technology and it has highly sophisticated signal conditioning ASIC with digital SPI interface. Small robust packaging guarantees reliable operation over product lifetime. The housing is suitable for SMD mounting and the component is compatible with RoHS and ELV directives. SCR1100-D02 is designed, manufactured and tested against high stability, reliability and quality requirements. The angular rate sensor provides highly stable output over wide ranges of temperature and mechanical noise. The bias stability is in the elite of MEMS gyros and the component has several advanced self diagnostics features.
