IMU-3000 Product Specification
Document Number: PS-IMU-3000A-00-01.1
Revision: 1.1
Release Date: 08/19/2010
1.2 Purpose and Scope
This document is a preliminary product specification, providing a description, specifications, and
design related information for the IMU-3000™ Inertial Measurement Unit (IMUTM). The IMU-3000
MPL Functional Specification describes in detail the Motion Processing Library: API and System
Layer routines needed for interfacing to the IMU-3000.
Electrical characteristics are based upon simulation results and limited characterization data of
advanced samples only. Specifications are subject to change without notice. Final specifications will
be updated based upon characterization of final silicon.
1.3 Product Overview
The IMU-3000 is the world’s first IMU solution with 6-axis sensor fusion for consumer applications.
The IMU-3000 has an embedded 3-axis gyroscope and Digital Motion Processor™ (DMP™)
hardware accelerator engine with a secondary I2C port that interfaces to third party digital
accelerometers to deliver a complete 6-axis sensor fusion output to its primary I2C port. This
combines both linear and rotational motion into a single data stream for the application. The device is
ideally suited for a wide variety of consumer products requiring a rugged, low-cost motion processing
solution for applications in game controllers, remote controls for broadband connected TVs and set
top boxes, sports, fitness, medical and other applications. By providing an integrated sensor fusion
output, the IMU-3000 offloads the intensive motion processing computation requirements from the
host processor, reducing the need for frequent polling of the motion sensor output and enabling use of
low cost, low power microcontrollers.
The IMU-3000 features a 3-axis digital gyro with programmable full-scale ranges of ±250, ±500,
±1000, and ±2000 degrees/sec (dps), which is useful for precision tracking of both fast and slow
motions. Rate noise performance sets the industry standard at 0.01 dps/√Hz, providing the highest-
quality user experience in pointing and gaming applications. Factory-calibrated initial sensitivity
reduces production-line calibration requirements. The part’s on-chip FIFO and dedicated I2C-master
accelerometer sensor bus simplify system timing and lower system power consumption; the sensor
bus allows the IMU-3000 to directly acquire data from the off-chip accelerometer without intervention
from an external processor, while the FIFO allows a system microcontrollers to burst read the sensor
data and then go to sleep while the IMU collects more data. Other industry-leading features include
on-chip 16-bit ADCs, programmable digital filters, a precision clock with 1% variation from -40°C to
85°C, an embedded temperature sensor, programmable interrupts, and a low 13mW power
consumption. Parts are available with an I2C serial interface, a VDD operating range of 2.1 to 3.6V,
and a VLOGIC interface voltage from 1.71V to 3.6V.
By leveraging its patented and volume-proven Nasiri-Fabrication platform, which integrates MEMS
wafers with companion CMOS electronics through wafer-level bonding, InvenSense has driven the
IMU-3000 package size down to a revolutionary footprint of 4x4x0.9mm (QFN), while providing the
highest performance, lowest noise, and the lowest cost semiconductor packaging to address a wide
range of handheld consumer electronic devices. The device provides the highest robustness by
supporting 10,000g shock in operation. The highest cross-axis isolation is achieved by design from
its single silicon integration.
The IMU-3000 was designed to connect directly with a third-party 3-axis digital accelerometer, which
slaves directly to the IMU-3000 master and can be clocked from the internal phase locked loop of the
IMU-3000 device, providing highly accurate timing for a true 6-axis motion processing solution
previously only available in costly and bulky inertial measurement units.
