FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The MMC3316xMT is a complete 3-axis magnetic
sensor with on-chip signal processing and integrated
I²C bus. The device can be connected directly to a
microprocessor, eliminating the need for A/D
converters or timing resources. It can measure
magnetic fields within the full scale range of 16
gauss, with 2 mG/LSB resolution and 2mG rms noise,
enabling heading accuracies of <1 degree in
electronic compass applications. Contact Memsic for
access to advanced calibration and tilt-compensation
algorithms.
In addition, an integrated SET/RESET function
enables the sensors to be “cleared” of any residual
magnetic polarization resulting from exposure to
strong external magnets. The SET/RESET function
can be performed prior to each measurement, or
periodically if desired, to maintain a stable sensor
offset over time.
The MMC3316xMT is packaged in a small low profile
LGA package (2.0 x 2.0 x 1.0 mm,) and with an
operating temperature rang from -40C to +85C.
The MMC3316xMT provides an I²C digital output with
400 KHz, fast mode operation.
