This application note describes the differences between FXAS21000 and FXAS21002. This note presents a recommended application schematic that can accommodate either device via zero-ohm jumper population changes. To enable easy software migration, minor register map and digital feature differences between the two parts are highlighted.

A section contains tables that describe the functions of the FXAS21000 and FXAS21002 pinouts. The most significant difference is Pin 8. On the FXAS21000, Pin 8 is not used. On the FXAS21002, Pin 8 is used to select the digital communications mode, either I2C or SPI. To select I2C mode, connect Pin 8 to GND. To select SPI mode, connect Pin 8 to VDDIO.

More functionality has been added to Pin 2 of the FXAS21002. In addition to being an interrupt output, Pin 2 can serve as an input to provide power state control.
