New power-efficient, low-noise device is ideally suited to Internet of Things, wearable, indoor navigation, and handheld applications
Geneva, September 9, 2014 – STMicroelectronics (NYSE: STM) a global semiconductor leader serving customers across the spectrum of electronics applications, the world’s top MEMS (Micro-Electro-Mechanical Systems) manufacturer and the leading supplier of MEMS for consumer and mobile applications 1, today announced its development of the first iNEMO™ Ultra product – an always-on, high-performance 6-axis combination accelerometer and gyroscope that sets new standards for device and system power efficiency, signal noise, and performance in motion sensors. In concert with ST’s ultra-low-power STM32 microcontrollers, the LSM6DS3 combos will create new possibilities for the development of battery-powered smart sensor systems to be embedded in mobile and wearable devices and innovative objects for the Internet of Things (IoT).
The tiny (2.5mm x 3.0mm x 0.8mm), iNEMO Ultra 6-axis inertial-sensor combo (3-axis accelerometer/3-axis gyroscope) delivers industry-leading noise performance while effectively managing system power with state-of-the-art technology that in testing has proven to be typically 20% more energy-efficient than the best alternative combos in low-power mode while delivering outstanding performance and protecting valuable board real estate.
This is in part, due to the market’s largest “smart” FIFO (First-In First-Out) memory (8kbytes) — at least 2 times larger than any else available. This flexible memory allows the LSM6DS3 to save and batch more data before waking up the system processor, saving overall system power, too. Moreover, ST has leveraged its robust and mature manufacturing processes for the production of its industry-leading micro-machined accelerometers and gyroscopes, while manufacturing its IC interfaces
using CMOS technology. This choice supports trimming of dedicated circuits to better match sensing-element characteristics.
“Our new 6-axis ultra-combo is designed to operate at the lowest power and best noise density in the market and will make Internet-of-Things devices far more efficient and convenient,” said Benedetto Vigna, ST Executive Vice President and General Manager of the Analog, MEMS & Sensors Group. “With this latest addition to our industry-leading portfolio, our mastery of our own full supply chain, and the expertise and leadership to build system-level efficiency into everything we make, ST continues to raise the bar for motion-sensor performance.”
The LSM6DS3 will be delivered as an optimized 2-chip system-in-package featuring high-performance 3-axis digital accelerometer and 3-axis digital gyroscope with integrated power-efficient modes down to 0.6mA in always-on working mode. The new combo combines always-on low-power features with superior sensing precision for best-in-class motion detection and analysis with ultra-low noise.
The LSM6DS3’s event-detection interrupts enable efficient and reliable motion tracking and context awareness that is implemented in hardware. This allows for recognition of free-fall events, 6D orientation, tap and double-tap sensing, activity or inactivity, and wake-up events. With ST’s experience in supporting the requirements of the main operating systems, the LSM6DS3 will be able to efficiently process real, virtual, and batch-mode sensors, saving power and enabling faster system reaction time. Indeed, the new combo is designed to implement in hardware Significant Motion, Tilt, Pedometer Functions, and Time Stamp, and to support the data acquisition of an external magnetometer with both hard and soft iron correction.
Finally, the LSM6DS3 will offer hardware flexibility to connect pins with different mode connections to external sensors to fulfill additional functionalities as a sensor hub, auxiliary SPI (Serial Peripheral Interface), and other vital capabilities.
The LSM6DS3 combo will be available in Q4 2014.
