FT232RQ-REEL from FTDI, in a QFN-32-EP(5x5). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCCIO | power_in | +1.8 V to +5.25 V supply for the UART interface and CBUS group pins. Tie to 3V3OUT for 3.3 V I/O or to VCC for +5 V CMOS I/O; may also be supplied from an external +1.8 V to +2.8 V rail sourced from the same supply as VCC. |
| 2 | RXD | input | Receiving asynchronous data input. |
| 3 | RI# | input | Ring Indicator control input. When remote wake-up is enabled in EEPROM, driving RI# low (20 ms active-low pulse) resumes the USB host from suspend. |
| 4 | GND | power_in | Device digital ground supply pin. |
| 5 | NC | unconnected | No internal connection. Do not connect. |
| 6 | DSR# | input | Data Set Ready control input / handshake signal. |
| 7 | DCD# | input | Data Carrier Detect control input. |
| 8 | CTS# | input | Clear To Send control input / handshake signal. |
| 9 | CBUS4 | output | Configurable CBUS output-only pin. EEPROM-configurable; factory default is SLEEP#. Available options include TXDEN, PWREN#, TXLED#, RXLED#, TX&RXLED#, SLEEP#, CLK48/24/12/6. |
| 10 | CBUS2 | bidirectional | Configurable CBUS I/O pin. EEPROM-configurable; factory default is TXDEN. Options include TXDEN, PWREN#, TXLED#, RXLED#, TX&RXLED#, SLEEP#, CLKx, CBitBangI/O, BitBangWRn, BitBangRDn. |
| 11 | CBUS3 | bidirectional | Configurable CBUS I/O pin. EEPROM-configurable; factory default is PWREN# (requires 10 kΩ pull-up to VCCIO). |
| 12 | NC | unconnected | No internal connection. Do not connect. |
| 13 | NC | unconnected | No internal connection. Do not connect. |
| 14 | USBDP | bidirectional | USB D+ data signal. Incorporates internal series resistor and 1.5 kΩ pull-up to +3.3 V for Full-Speed identification. |
| 15 | USBDM | bidirectional | USB D- data signal. Incorporates internal series resistor. |
| 16 | 3V3OUT | power_out | +3.3 V output from the integrated LDO regulator; decouple to ground with a 100 nF capacitor. Supplies the internal USB transceiver and USBDP pull-up; up to 50 mA available for external logic and may also feed VCCIO. |
| 17 | GND | power_in | Device digital ground supply pin. |
| 18 | RESET# | input | Active-low reset input. Can be driven by an external device to reset the FT232R; leave unconnected or pull up to VCC if unused. |
| 19 | VCC | power_in | +3.3 V to +5.25 V supply to the device core. Minimum operating voltage is +4.0 V when using the internal clock generator; +3.3 V operation is possible when driven by an external crystal oscillator. |
| 20 | GND | power_in | Device digital ground supply pin. |
| 21 | CBUS1 | bidirectional | Configurable CBUS I/O pin. EEPROM-configurable; factory default is RXLED#. |
| 22 | CBUS0 | bidirectional | Configurable CBUS I/O pin. EEPROM-configurable; factory default is TXLED#. |
| 23 | NC | unconnected | No internal connection. Do not connect. |
| 24 | AGND | power_in | Device analogue ground supply for the internal clock multiplier. |
| 25 | NC | unconnected | No internal connection. Do not connect. |
| 26 | TEST | input | IC test-mode enable. Must be tied to GND for normal operation, otherwise the device will appear to fail. |
| 27 | OSCI | input | 12 MHz oscillator cell input. Optional; leave unconnected for normal operation with the internal oscillator. Used with an external crystal, ceramic resonator, or oscillator. |
| 28 | OSCO | output | 12 MHz oscillator cell output. Optional; leave unconnected for normal operation with the internal oscillator. |
| 29 | NC | unconnected | No internal connection. Do not connect. |
| 30 | TXD | output | Transmit asynchronous data output. |
| 31 | DTR# | output | Data Terminal Ready control output / handshake signal. |
| 32 | RTS# | output | Request To Send control output / handshake signal. |
