Figure 17. Typical application
A central processor/controller typically located on the system main
board can use the 400 kHz I2C/SMBus to poll the PCA9500 devices
located on the system cards for status or version control type of
information. The PCA9500 may be programmed at manufacturing to
store information regarding board build, firmware version,
manufacturer identification, configuration option data
… Alternately,
these devices can be used as convenient interface for board
configuration, thereby utilizing the I2C/SMBus as an intra-system
communication bus.
