For BMA253, pin 11(PS) is protocol selection pin. So pin 10(CSB) could be DNC for I2C connection.
For BMA456, pin 10(CSB) is protocol selection pin.
Thank you for the reply. I know that pin 10 can be left floating if I use the the I2C interface on the BMA253, but can it be set to VDDIO as well? This would make my circuit compatible with other sensors. Otherwise I would have to add a jumper resistor.
Thank you very much for the reply. I will keep the BMA253 in the design and connect pin 10 to VDDIO. If the BMA253 is no longer available I can easily switch to another sensor with suitable specs.
