Unspecified 

ITG-3200 Product Specification

Document Number: PS-ITG-3200A-00-01.4

Revision: 1.4

Release Date: 03/30/2010

1.2 Purpose and Scope

This document is a preliminary product specification, providing a description, specifications, and design related

information for the ITG-3200TM. 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 ITG-3200 is the world’s first single-chip, digital-output, 3-axis MEMS gyro IC optimized for gaming, 3D mice,

and 3D remote control applications. The part features enhanced bias and sensitivity temperature stability, reducing the

need for user calibration. Low frequency noise is lower than previous generation devices, simplifying application

development and making for more-responsive remote controls.

The ITG-3200 features three 16-bit analog-to-digital converters (ADCs) for digitizing the gyro outputs, a user-selectable

internal low-pass filter bandwidth, and a Fast-Mode I2C (400kHz) interface. Additional features include an embedded

temperature sensor and a 2% accurate internal oscillator. This breakthrough in gyroscope technology provides a

dramatic 67% package size reduction, delivers a 50% power reduction, and has inherent cost advantages compared to

competing multi-chip gyro solutions.

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 ITG-3200 package size down to

a revolutionary footprint of 4x4x0.9mm (QFN), while providing the highest performance, lowest noise, and the lowest

cost semiconductor packaging required for handheld consumer electronic devices. The part features a robust 10,000g

shock tolerance, as required by portable consumer equipment.

For power supply flexibility, the ITG-3200 has a separate VLOGIC reference pin, in addition to its analog supply pin,

VDD, which sets the logic levels of its I2C interface. The VLOGIC voltage may be anywhere from 1.71V min to VDD

max.
