Transmit Asynchronous Data Output.
Data Terminal Ready Control Output / Handshake Signal.
Request to Send Control Output / Handshake Signal.
Receiving Asynchronous Data Input.
Ring Indicator Control Input. When remote wake up is enabled in the internal EEPROM
taking RI# low (20ms active low pulse) can be used to resume the PC USB host
controller from suspend.
Data Set Ready Control Input / Handshake Signal.
Data Carrier Detect Control Input.
Clear To Send Control Input / Handshake Signal.
Configurable CBUS output only Pin. Function of this pin is configured in the device
internal EEPROM. Factory default configuration is SLEEP#. See CBUS Signal Options,
Table 3.9.
Configurable CBUS I/O Pin. Function of this pin is configured in the device internal
EEPROM. Factory default configuration is TXDEN. See CBUS Signal Options, Table 3.9.
+3.3V output from integrated LDO regulator. This pin should be decoupled to
ground using a 100nF capacitor. The purpose of this output is to provide the
internal +3.3V supply to the USB transceiver cell and the internal 1.5kΩ pull up
resistor on USBDP. Up to 50mA can be drawn from this pin to power external logic if
required. This pin can also be used to supply the VCCIO pin.
+3.3V to +5.25V supply to the device core. (See Note 1).
Device analogue ground supply for internal clock multiplier.
No internal connection. Do not connect.
Active low reset. Can be used by an external device to reset the FT232R. If not
required can be left unconnected, or pulled up to VCC.
Puts the device into IC test mode. Must be tied to GND for normal operation,
otherwise the device will appear to fail.
Input 12MHz Oscillator Cell. Optional – Can be left unconnected for normal
operation. (See Note 2).
Output from 12MHZ Oscillator Cell. Optional – Can be left unconnected for normal
operation if internal Oscillator is used. (See Note 2).
