14 Application information

The FXPS7115D4 sensor can operate in two modes: I2C and SPI. The application

diagrams in Figure 25 and Figure 26 show the modes and their respective biasing and

bypass components.

The sensor can be configured to operate in SPI mode to read the user registers, self-test

and diagnostics information. The application diagram in Figure 26 shows the SPI and the

respective biasing and bypass components.

Note: A gel is used to provide media protection against corrosive elements which

may otherwise damage metal bond wires and/or IC surfaces. Highly pressurized gas

molecules may permeate through the gel and then occupy boundaries between material

surfaces within the sensor package. When decompression occurs, the gas molecules

may collect, form bubbles and possibly result in delamination of the gel from the material

it protects. If a bubble is located on the pressure transducer surface or on the bond wires,
