FUNCTIONAL BLOCK DIAGRAM
The MMC328xMA is a 3-axis magnetic sensor, it is a
complete sensing system with on-chip signal
processing and integrated I2C bus, allowing the device
to be connected directly to a microprocessor
eliminating the need for A/D converters or timing
resources. It can measure magnetic field with a full
range of ±8 gausses.
The MMC328xMA is packaged in an ultra small low
profile BGA package (2.0 x 2.0 x 1.2 mm, including
the 0.2mm height solder ball) and is available in
operating temperature ranges of -40°C to +85°C.
The MMC328xMA provides an I2C digital output with
400 KHz, fast mode operation.
