4.1. Supply Voltage and Power Management
BMA400 has two distinct power supply pins:
 VDD is the main power supply.
 VDDIO is a separate power supply pin used for supplying power for the digital communication
interface.
There are no limitations with respect to the voltage level applied to the VDD and VDDIO pins, as long
as it lies within the respective operating range. Furthermore, the device can be completely switched
off (VDD=0V) while keeping the VDDIO supply within operating range or vice versa. However if the
VDDIO supply is switched off, all interface pins (CSB, SDX, SCX) must be kept close to GNDIO
potential. No constraints exist for the minimum slew-rate of the voltage applied to the VDD and VDDIO
pins.
