System Plus Consulting is proud to publish the reverse costing report of the new 6-Axis electronic compass supplied by STMicroelectronics.

The LSM303D is a system-in-package featuring a 3-axis magnetometer and a 3-axis accelerometer. With a 3x3x1mm package size, it belongs to the smallest e-Compasses for consumer applications.

The 3-Axis accelerometer uses the TSV process of ST in order to remove the area reserved for I/O pads. The magnetometer dies use the latest process of Honeywell.

The LSM330D is targeted for consumer applications: Tilt compensated compass, Map rotation, Position detection… It provides accurate output across full-scale ranges up to ±16g (linear acceleration) and ±12 Gauss (magnetic field).

This report provides complete teardown of the 6-Axis electronic compass with:
