Pin #
1. Connect 100 nF SMD capacitor between each supply voltage and ground level.
2. Connect 1 µF capacitor between each supply voltage and ground level.
3. Use one regulator for analog and digital supply (AVDD and DVDD).
4. Use separate regulator for digital IO supply (DVIO).
5. Xreset is needed always in start up: when Xreset is low, raise power supplies inside
6. INT-pin is used with output buffer as well as in Free Fall and Motion Detection mode.
7. Serial interface (SPI or I
Recommended circuit diagram for the SCA3000 with SPI interface is presented in Figure 15 below.
