Figure 8.4 Application Example showing USB to I2C (Master) Converter

This example shows the CNFGx pins set for mode 011 – I2C (Master).

Only two signal lines are required for I2C interfacing. The clock is an output from the FT311D while the

data line is bi-directional.

Examples of I2C peripherals include EEPROMs, Real time Clocks (RTC) and audio or video codecs.

The unused pins may be left unterminated.
