FT2232H DUAL HIGH SPEED USB TO MULTIPURPOSE UART/FIFO IC
Datasheet Version 2.10
Clearance No.: FTDI#77
3.4 Configured Pins
The following sections describe the function of the configurable pins referred to in the table given in
Section 3.2 which is determined by how the FT2232H is configured.
3.4.1 FT2232H pins used in an RS232 interface
The FT2232H channel A or channel B can be configured as an RS232 interface. When configured in this
mode, the pins used and the descriptions of the signals are shown in Table 3.4.
Channel A
Pin No.
Channel B
Pin No.
Name
Type
RS232 Configuration Description
16
38
TXD
OUTPUT
TXD = transmitter output
17
39
RXD
INPUT
RXD = receiver input
18
40
RTS#
OUTPUT
RTS# = Ready To send handshake output
19
41
CTS#
INPUT
CTS# = Clear To Send handshake input
21
43
DTR#
OUTPUT
DTR# = Data Transmit Ready modem signaling line
22
44
DSR#
INPUT
DSR# = Data Set Ready modem signaling line
23
45
DCD#
INPUT
DCD# = Data Carrier Detect modem signaling line
24
46
RI#
INPUT
RI# = Ring Indicator Control Input. When the Remote Wake
up option is enabled in the EEPROM, taking RI# low can be
used to resume the PC USB Host controller from suspend.
(Also see note 1, 2, 3 in section 4.12)
26
48
TXDEN
OUTPUT
TXDEN = (TTL level). For use with RS485 level converters.
29
54
RXLED#
OUTPUT
RXLED = Receive signaling output. Pulses low when receiving
data (RXD) via USB. This should be connected to an LED.
30
55
TXLED#
OUTPUT
TXLED = Transmit signaling output. Pulses low when
transmitting data (TXD) via USB. This should be connected to
an LED.
