InvenSense unveils MPU-6515 SoC for Android KitKat 4.4

InvenSense has unveiled the 6-axis MPU-6515 MEMS SoC and corresponding MotionApps software platform specifically designed for the Android KitKat. The MPU-6515 includes an improved version of InvenSense's Digital Motion Processor (DMP) to offload motion protocols and algorithms from the Application Processor (AP) as required by Android KitKat for low-power inertial location tracking and contextual awareness. At 3x3x0.9mm, the MPU-6515's integrated gyroscope, accelerometer, and DMP is intended for wearables, smartphones, and tablets that run the Android 4.4 operating system.

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 Application Processor when critical motion events require attention from other parts of the system. The company said that in addition to lowering power consumption for always-on location and context tracking applications, MPU-6515 reduces system cost and complexity by connecting directly with the Application Processor, thus eliminating the need for additional motion processing ICs within the Android 4.4 operating system.

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, according to the company. The MPU-6515 is currently in production and can be found in the first Android flagship devices running Android Kit Kat.
