Look at an2824.

It might be as easy to write your own bit bashing routines for I2C. Even with the newer routines in an2824, some people have suggested that it may still be necessary to provide means to ''clock out'' the I2C bus if a device ''hangs'' the bus (so you may as well do the whole job).

That said, I'm using the ST routines to read and write an M24C64 EEPROM and they work.
