Automotive 6DoF inertial sensor
This sensor contributes to advanced system such as ADAS (Advanced Driver Assistance Systems), autonomous driving, and more, in order to detect 6DoF data which are composed by 3 axis (forward and backward, left and right, up and down) of acceleration(Acc) and gyro data.

Functional safety compliance for automotive safety system (ISO26262)
Compatible with ASIL-D functional safety development: This sensor complies with ISO26262 according to the user system safety level (ASIL: Automotive Safety Integrity Level), supports the construction of argument by providing necessary documents, and guarantees the quality for automotive applications.
Highly accurate 6DoF MEMS sensors on single die, improving system design flexibility
Orthogonality ≦0.01° between Gyro and Accel. axis
The misalignment between Acc and Gyro axis deteriorates data accuracy because Acc and Gyro sensors are comprised of the multiple chips in the conventional inertial sensor.
6in1 inertial sensor adapts one single chip solution in which all 6 axis of Acc and Gyro sit together.
And all 6 axis are orthogonal and enables high accuracy data in spite of the installation posture.
Compact and simple ECU system design
6DoF one package: 4.5 x 4.5 x 1.1 mm
This sensor adapts electrostatic MEMS and encapsulates MEMS and ASIC by wafer level packaging to realize the world compact and low profile 6DoF inertial sensor.
This enables automotive ECU System to be simple and smaller.
- Au Wire
- Leadframe
Dimple processing contributes to improved mounting quality
Dimple processing enables soldering fillet visible at the side of lead terminals.
This can confirm each terminal soldering correctly to the substrate land by the fillet visible inspection.
