3-Axis Digital Compass Module
HMC6343
Advanced Information
The Honeywell HMC6343 is a fully integrated compass module that
combines 3-axis magneto-resistive sensors and 3-axis MEMS
accelerometers with the required analog and digital support circuits, and
algorithms for heading computation. By combining the sensor elements,
processing electronics, and firmware in to a 9.0mm by 9.0mm by
1.9mm LCC package, Honeywell offers a complete, ready to use tilt-
www.DatacSohmeept4eUn.csoamted electronic compass. This provides design engineers with
the simplest solution to integrate high volume, cost effective compasses
into wireless phones, consumer electronics, vehicle compassing, and
antenna positioning.
The HMC6343 utilizes Honeywell’s Anisotropic Magnetoresistive (AMR)
technology that provides advantages over other magnetic sensor technologies. The sensors feature precision sensitivity
and linearity, solid-state construction with very low cross-axis sensitivity designed to measure both direction and
magnitude of Earth’s magnetic fields. Honeywell’s Magnetic Sensors are among the most sensitive and reliable low-field
sensors in the industry.
Honeywell continues to maintain product excellence and performance by introducing innovative solid-state magnetic
sensor solutions. These are highly reliable, top performance products that are delivered when promised. Honeywell’s
magnetic sensor solutions provide real solutions you can count on.
