• Manufacturer Part Number: BMA222
• Description: 3-AXIS ACCELEROMETER DIGITAL SMD
• Manufacturer: Bosch Sensortec

Specifications of BMA222

• Lead Free Status / Rohs Status: Lead free / RoHS Compliant

Register (0x38) contains the compensation value for filtered data for the x-axis. The contents of
each of the registers (0x38) to (0x3D) is added to the corresponding acceleration data; it can be
set either automatically by one of the implemented compensation algorithms or manually. These
registers are image registers of registers in the EEPROM; the content of the EEPROM is copied
to them after every reset.
Register (0x39) contains the compensation value for filtered data for the y-axis.
Register (0x3A) contains the compensation value for filtered data for the z-axis.
Register (0x3B) contains the compensation value for unfiltered data for the x-axis.
Register (0x3C) contains the compensation value for unfiltered data for the y-axis.
