L3G4200D: 3-axis digital output gyroscope
Introduction
This document is intended to provide usage information and application hints related to ST’s
L3G4200D 3-axial digital gyroscope.
The L3G4200D is a three-axis angular rate sensor with a digital I²C/SPI serial interface
standard output.
The device has a full scale of ±250/±500/ ±2000 dps and is capable of measuring rates with
a user-selectable bandwidth.
The device may be configured to generate interrupt signals by an independent wake-up
event. Thresholds and timing of the interrupt generator are programmable by the end user
on the fly.
The L3G4200D has an integrated 32-level first-in first-out (FIFO) buffer allowing the user to
store data in order to limit intervention by the host processor.
The L3G4200D is available in a small thin plastic land grid array package (LGA 4x4x1.1)
and it is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
The ultra-small size and weight of the SMD package make it an ideal choice for handheld
portable applications such as cell phones and PDAs, or any other application where
reduced package size and weight are required.
