Features
General Description
SCC1300-D04 is a combined high performance gyroscope and accelerometer component. The sensor is based on VTI's
proven capacitive 3D-MEMS technology. The component integrates angular rate and acceleration sensing together with
flexible separate digital SPI interfaces. 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.
SCC1300-D04 is designed, manufactured and tested against high stability, reliability and quality requirements. The
angular rate and acceleration sensors provide highly stable output over wide ranges of temperature and mechanical
noise. The angular rate sensor bias stability is in the elite of MEMS gyros and it is also exceptionally insensitive to all
mechanical vibrations and shocks. Component has several advanced self diagnostics features.
