• This full reverse costing study has been conducted to provide insight on technology data, manufacturing cost and selling

price of the STMicroelectronics LSM9DS0 component.

• The LSM9DS0 is a 9-axis MEMS IMU (3-axis gyroscope + 3-axis accelerometer + 3-axis magnetometer).

• It is suitable for portable applications: Indoor navigation, Smart user interface, Advanced gesture recognition, Gaming and

virtual reality input device, Display/map orientation and browsing, eCompass, Position and motion detection functions,

Click/double click recognition, Intelligent power saving for handheld devices).

• The LSM9DS0 provides accurate output across full-scale ranges up to ±2000dps (rotational acceleration), ±16g (linear

acceleration) and ±12 Gauss (magnetic field).

• Compatible with SMD process, the LSM9DS0 is provided in a 4x4x1mm LGA 24-pin package.

• Note : The LSM9DS0 integrates a 3-axis Gyroscope, a 3-axis Accelerometer and a 3-axis magnetometer. Notations bellow

are used in this report :

• One die constitute the 3-axis Gyroscope and the 3-axis Accelerometer, it is called :

MEMS Gyro/Accelero: A microsystem which comprise two parts, MEMS Cap and MEMS Sensor.

• Two dies constitute the 3-axis Magnetometer, they are called :

X/Y-Axis magnetometer : A sensor die which is used to measure the magnetic field on the X-axis and Y-axis.

Z-Axis magnetometer A sensor die which is used to measure the magnetic field on the Z-axis.

• One die constitutes the control IC for the gyroscope function, it is called :

Gyroscope ASIC : An IC die which is used to control the MEMS gyroscope.

• One die constitutes the control IC for the accelerometer and magnetometer functions, it is called :

Accelero/Magneto ASIC : An IC die which is used to control the MEMS accelerometer and the 3 axes of the

magnetometer.

• These notations are used both in this report and in the excel file.

Reverse costing analysis represents the best cost/price evaluation given the publically available data, and estimates completed by industry experts.

Given the hypothesis presented in this analysis, the major sources of correction would lead to a +/- 10% correction on the manufacturing cost (if all parameters are cumulated).

These results are open for discussion. We can reevaluate this circuit with your information. Please contact us:
