InvenSense Inc. has rolled out the 6-axis MPU-6515 MEMS SoC and corresponding MotionApps software platform optimised to support the latest functions introduced in Android KitKat. The SoC features an enhanced version of InvenSense's patented Digital Motion Processor (DMP) to offload complex motion protocols and algorithms from the application processor (AP) as required by Android KitKat for low power inertial location tracking and contextual awareness. At 3 x 3 x 0.9mm, the MPU-6515's integrated gyroscope, accelerometer and DMP is aimed at next-generation wearables, smartphones and tablets that run the Android 4.4 OS, stated the company.

Android 4.4 defines several new sensor functions including significant motion interrupt, pedometer, step event and event batching. The MPU-6515 performs these functions on-chip, only waking the AP when critical motion events require attention from other parts of the system. Beyond significantly lowering power consumption for always-on location and context tracking applications, MPU-6515 reduces system cost and complexity by connecting directly with the AP, thus eliminating the need for additional motion processing ICs within the Android 4.4 operating system, noted InvenSense.

Footprint and pin compatible with the InvenSense MPU-6500, existing smartphone and tablet designs running Android Jelly Bean can be easily upgraded to the MPU-6515 and associated MotionApps software for Android KitKat. The MPU-6515 is in production and can be found in the first Android flagship devices running Android Kit Kat.
