Three-axis digital gyroscope

13 October 2010 Analogue, Mixed Signal, LSI

STMicroelectronics has extended its motion sensor portfolio with a high-performance, 3-axis gyroscope that embeds a FIFO (first-in first-out) memory block for smart power management.

The latest addition to ST’s MEMS portfolio, the L3G4200DH integrates an on-chip FIFO memory block that stores up to 96 levels, split in 32 sample sets of x-, y-, and z-axis data. This feature removes the need for continuous communication of the angular rate data between the sensor and the host processor, which can then spend more time in a sleep mode and decrease overall system power consumption. Application designers can program the FIFO for several different operating modes to raise a dedicated watermark (reference) interrupt when the memory is filled to a desired level.

All of ST’s MEMS gyroscopes employ a single sensing structure for motion measurement along all three orthogonal axes. This design approach eliminates all interference between the axes, increasing accuracy and reliability in a wide range of consumer and industrial applications, including advanced user interfaces for gaming and portable devices, motion tracking and camera image stabilisation.

The L3G4200DH boasts output stability over time and temperature, removing the need for any further calibration on the customer side. With advanced filtering capabilities for improved noise reduction and application flexibility, the user is able to limit the selected bandwidth through embedded high- and low-pass filters. The sensor and the ASIC interface are housed inside a 4 x 4 x 1 mm package. The gyroscope couples a 16-bit data output with a wide set of user-programmable full-scale ranges from ±250 dps up to ±2000 dps, with the low full-scale values for high accuracy of slow-motion sensing and the high range to detect and measure very fast gestures and movements.
