press release

In a trend-setting move for the consumer electronics industry, Bosch Sensortec has integrated two triaxial MEMS sensors in a single package. This combination of an acceleration sensor and a gyroscope yields the BMI055, the smallest Inertial Measurement Unit in the market. The BMI055 is designed to meet the requirements of advanced consumer electronics applications with six degrees of freedom (6DoF) such as game consoles or gaming applications in smartphones and tablet computers.

Designers benefit from a one-stop solution for 6DoF applications in which the elements – acceleration sensor, gyroscope, and software – are all of a piece. Supplied in a LGA 3.0 x 4.5 x 0.95 mm package, the BMI055 offers the smallest footprint in the market. With its high degree of integration, the BMI055 reduces the bill of material (BoM) and at the same time facilitates the qualification process. Since it lowers the component count, it also simplifies assembly.

Exact measurement, flexible design options
With a resolution of 16 bit for the gyroscope and 12 bit for the accelerometer, combined with excellent signal/noise ratio, the unit provides precise, reliable measurement results. For greater design flexibility, the measurement range of the sensors is programmable – ±125 °/s to ±2000 °/s for the gyroscope and ±2 g to ±16 g for the accelerometer. The latter also shows a low zero-g offset of typically only 70 milli-g. I2C and SPI digital interfaces offer versatile communication options. For use in battery-powered consumer devices, the BMI055 exhibits very low power consumption.

Along with the BMI055, Bosch Sensortec offers a custom software solution which combines measurement data of both sensors, providing optimized sets of data for various target applications. In combination with an optional geomagnetic sensor, the software even enables the design of 9DoF applications.

World leading design and manufacturing competency
The BMI055 Inertial Measurement Unit is based on Bosch Sensortec's proven MEMS sensor technology, the result of 15 years of experience in the field of gyroscope development. The BMI055 further expands Bosch Sensortec’s product spectrum of advanced MEMS sensors. The company owns the entire value chain including sophisticated MEMS sensor technology IP, high-volume manufacturing experience and software expertise. For the customer, this translates into advanced product design quality and excellent delivery performance – decisive factors in today’s demanding markets.

Bosch Sensortec GmbH is a fully owned subsidiary of Robert Bosch GmbH, dedicated to the consumer electronics world offering a complete portfolio of micro-electro mechanical systems (MEMS) sensors and solutions that enable mobile devices to feel and sense the world around them. Bosch Sensortec develops and markets a wide portfolio of MEMS sensors and solutions for smart phones, tablets, wearable devices and IoTS (Internet of Things & Services) applications.

The product portfolio includes 3-axis acceleration, gyroscope and geomagnetic sensors, integrated 6- and 9-axis as well as environmental sensors and a comprehensive software portfolio. Since its foundation in 2005 Bosch Sensortec emerged as the technology leader in the addressed markets. The Bosch Group has been the global market leader for MEMS sensors since 1998 and has to date sold more than 4 billion MEMS sensors.

The Bosch Group is a leading global supplier of technology and services. In 2013, its roughly 281,000 associates generated sales of 46.1 billion euros. (NB: Due to a change in accounting policies, the 2013 figures can only be compared to a limited extent with the 2012 figures). Its operations are divided into four business sectors: Mobility Solutions, Industrial Technology, Consumer Goods, and Energy and Building Technology. The Bosch Group comprises Robert Bosch GmbH and its roughly 360 subsidiaries and regional companies in some 50 countries. If its sales and service partners are included, then Bosch is represented in roughly 150 countries. This worldwide development, manufacturing, and sales network is the foundation for further growth. In 2013, the Bosch Group invested some 4.5 billion euros in research and development and applied for some 5,000 patents. This is an average of 20 patents per day. The Bosch Group's products and services are designed to fascinate, and to improve the quality of life by providing solutions which are both innovative and beneficial. In this way, the company offers technology worldwide that is “Invented for life.”
