TI's TCA9554 is an 8-bit I2C I/O expander.
 
This example demonstrates how to use the I2C library with this chip.

================================================================================
uc              Micro controller
Xilinx-SP601    Xilinx Spartan-6 Eval board
                uses the J13 GPIO header for the I2C SCL and SDA signals,
                the TCA9554 interrupt signal, 3.3V power, and GND.
                Note:  The 3.3V power is OK because the Spartan-6 LVCMOS25 I/Os
                are 4.1V tolerant.
