CY7C68013 I2C-compatible Interface

Question: Can the I2C interface of EZ-USB be used for general purpose applications such as writing/reading to and from the internal registers of an I2C slave device?



Yes, it is possible to access other I2C slave devices such as EEPROMs, RTCs, temperature sensors, etc. through the I2C-compatible interface.

However, the I2C-compatible interface cannot be mastered by an outside I2C controller, as the interface on the FX2 supports a master-only mode. In addition, the internal EZ-USB registers cannot be accessed via this interface.
