Second Generation Electronic Compass, very low power consumption and tiny footprint (2.2x2.2mm²) thanks to an optimized integration

The BMC150 combines a 12-bit 3-Axis accelerometer and a wide-range 3-Axis geomagnetic sensor in a 2.2x2.2mm LGA package (the smallest footprint at its introduction). All the functionalities are developed and manufactured by Bosch.

Compared to its predecessor BMC050, the BMC150 achieve almost 50% footprint reduction. This reduction has been made possible by the integration of the second generation of Bosch geomagnetic sensor where the 3-Axis are integrated on a single die compared to 3 separates dies for the previous generation.

The magnetic sensor still uses Bosch FlipCore technology for X/Y-Axis sensing and Hall element for Z-Axis sensing. The MEMS accelerometer is also an evolution of the one found in BMC050.

The BMC150 is a very low power (190µA) and high resolution (0.3µT) 6-axis digital compass targeted for consumer mobile applications.

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.
