Low-power motion platform combines high-performance accelerometer and MCU technology to simplify sensor fusion.
More than 6 billion motion sensors are expected to ship in mobile handsets and tablets by 2016, according to analyst firm IHS. Systems designers rely on sophisticated MEMS sensors to enable compelling functionality in smart devices ranging from tablets to gaming consoles to sports, eHealth and activity monitors. To help developers more easily add, program and manage increasing sensor content within devices, Freescale Semiconductor (NYSE: FSL) is introducing a new Xtrinsic intelligent sensor hub that serves as a highly advanced sensor fusion platform.
Designed to exceed basic 3-axis sensor market requirements, Freescale’s Xtrinsic FXLC95000CL sensor hub integrates an on-board accelerometer with capability to manage multiple external sensors. The solution provides an ideal platform for making smarter system-level decisions by enabling complex calculations required for sensor fusion algorithms via interpreted sensing information and control rather than simple raw data processing.
Using the sensor hub, designers can efficiently scale a basic 3-axis accelerometer system up to a full 9-axis inertial measurement unit with altimetry, ambient light sensing, temperature sensing, humidity sensing and other capabilities. Exceptional scalability and integration allow sensor data to be processed locally, offloading compute cycles from the host processor and ultimately reducing system power consumption while boosting performance.
“With the rapidly multiplying number of sensors in everyday products, it is becoming increasingly complex for systems designers to manage all of the sensor data efficiently, while also accounting for potential future functionality,” said Babak Taheri, vice president and general manager of Freescale’s Sensor and Actuator Solutions Division. “The open architecture of Freescale’s hub solution gives designers the flexibility they need to create innovative applications without requiring a hardware change. It also allows designers to connect other sensors to the hub, which increases the variety of applications it can support – anything from medical monitoring to improving your golf swing.”
The Xtrinsic FXLC95000CL combines a 32-bit ColdFire V1 MCU core, 128K flash memory and 16K RAM with an open architecture and development support from a suite of code development tools, including the award-winning CodeWarrior Integrated Development Environment (IDE). To help jump-start product creation, Freescale also offers a software library suite that includes the Freescale MQX™ operating system, a hardware abstraction layer, a sensor manager and popular applications such as eCompass software. The open architecture programmability and supported API allows software developers to quickly create an intelligent platform for managing multiple sensors for a variety of applications including pedometers, shock event trackers, 9-axis inertial measurement units, context awareness solutions, device orientation detection solutions and more.
