Table 1.1 TTL-232RG Generic Cables Descriptions and Part Numbers

Note 1: Fixed 3.3V signals and supply.

Note 2: Any regulator from 1.8V to 5V can be used. 1.8V and 3.3V versions are standard products.

Others values are customized at the factory.

Note 3: Any INPUT voltage can be supplied by the customer from 1.8V (min value of VCCIO) to +5.25V

(Max value of VCCIO)

Note 4: The VCC power output signal (RED wire) is 3.3V. The source of 3.3V is the FT232R regulator output, which is

switched onto the power output signal.

Note 5: The VCC power output signal (RED wire) is 3.3V. The source of 3.3V is on board 3.3V regulator output, which

is switched onto the power output signal

Note 6: The VCC power output signal (RED wire) is 1.8V. The source of 1.8V is on board 1.8V regulator output, which

is switched onto the power output signal

Note 7: The VCC power output signal (RED wire) is 5.0V. The source of 5.0V is the USB VBUS input, which is

switched onto the power output signal. At the time of releasing these cables, this cable was not available. It

will become available at a later date. Please contact FTDI Sales for further information.

Note 8: The VCC power input signal (RED wire) is an output from customer electronics, an input to the cable. This

value=i/pV. The source of i/pV is from customer’s interface logic and this is used to drive the VCCIO and
