BMI160 flyerNew 6-Axis Inertial unit from Bosch, with a very low power consumption accelerometer and a footprint of only 3x2.5mm²

Bosch is now the top MEMS supplier with a production of more than 4 millions MEMS per day. This strong growth is due to both consumer applications and automotive applications.

With a size of only 7.5mm² (3x2.5mm), the BMI160 is the smallest 6-Axis IMU MEMS on the market and features 60% volume reduction compared to previous BMI055. This size reduction has been made possible by the use of a new design and process for the MEMS Gyro and by the integration in one ASIC die for the control of both MEMS. The BMI160 is a 16-bit digital resolution accelerometer and gyroscope well suited for applications requiring extremely small form factors.

Bosch has worked on the power consumption with a low power mode for the significant motion and step detector functions, using a “7-axis” accelerometer. Moreover, the unique ASIC die can perform the fusion of the data from the accelerometer and gyroscope with those from an external sensor.

Consumer 6-Axis MEMS IMU Cost Comparison (Bosch Sensortec BMI055 & BMI160, Invensense)



Across the Enterprise, from marketing to purchasing and R&D, product manufacturing cost is a major factor which has to be measured and then optimized. Since 1993, System Plus Consulting’s mission has been to develop and sell the right tools and services to meet these costing requirements.

System Plus Consulting utilizes an engineering approach to cost. Cost models and technology expertise are combined to provide customers with an accurate and objective estimation of manufacturing costs and selling prices.

Headquartered in Nantes, France, System Plus Consulting is specialized in technology and cost analysis of electronic components and systems. During our 20 years in business, we have built and refined detailed cost models as the primary tools for hundreds of analyses. The highly qualified System Plus cost engineers combine broad and deep skills in semiconductor and electronics technologies with years of experience in cost modeling.

We offer:
− Custom reverse costing analyses: technology analysis followed by cost evaluation
− Standard reverse costing reports: regular publications on innovative products (available from our catalogue)
− Costing tools: software tools combining models and data to perform cost analysis

System Plus Consulting analyzes any type of electronic devices and systems, with a special focus on semiconductor technologies. Major fields of technology and cost expertise are:
− Integrated Circuits
− Power Devices and Modules
− MEMS & Sensors
− Photonics: LED, Image Sensors
− Packaging including wafer level
− Electronic Boards and Systems

Our analyses are used by Purchasing Departments to measure their suppliers’ cost structure, R&D Departments to confirm technological choices depending on their impact on costs, and Benchmarking/Marketing Departments to monitor the products on the market.

System Plus Consulting is committed to provide a high level of service:
− Delivery of reports and custom analyses with a minimum lead time.
− Results presentation and online Q&A sessions when support is needed.
− Open methodology and full confidentiality in order to maintain a trustful collaboration.

Since 2008, our partnership with YOLE Développement has allowed us to stay at the forefront of technologies and has added a market view to our reports.
