IAM-20680HT
High Performance Automotive 6-Axis MotionTracking Device
GENERAL DESCRIPTION
APPLICATIONS
The IAM-20680HT is a 6-axis MotionTracking device for
Automotive non-safety applications that combines a 3-
axis gyroscope and a 3-axis accelerometer in a thin
3x3x0.75mm3 (16-pin LGA) package. It also features a
4096-byte FIFO that can lower the traffic on the serial
bus interface and reduce power consumption by allowing
the system processor to burst read sensor data and then
go into a low-power mode. IAM-20680HT, with its 6-axis
integration, enables manufacturers to eliminate the
costly and complex selection, qualification, and system
level integration of discrete devices, guaranteeing
optimal motion performance.
IAM-20680HT address a wide range of Automotive
applications, including but not limited to:
•
•
•
Navigation Systems Aids for Dead Reckoning
Lift Gate Motion Detection
Accurate Location for Vehicle to Vehicle and
Infrastructure
•
•
•
•
•
View Camera Stabilization and Vision Systems
Head-up display (HUD) and augmented reality HUD
Car Alarm
Telematics
Insurance Vehicle Tracking
ORDERING INFORMATION
The gyroscope has a programmable full-scale range of
±250 dps, ±500 dps, ±1000 dps and ±2000 dps. The
accelerometer has a user-programmable accelerometer
full-scale range of ±2g, ±4g, ±8g, and ±16g. Factory-
calibrated initial sensitivity of both sensors reduces
production-line calibration requirements.
