CY8C9520A as a viable alternative to MCP23017?

has anyone had experience using the CY8C9520A i2c port expander? I'm looking at it as an alternative to the MCP23017, because it gives me access to all 7 i2c address bits, at the expense of a few data lines.

I'm planning to use it to interface with a raspberry pi and drive an LCD display, a few buttons, and a few LEDs.
