FT2232C Dual USB UART / FIFO I.C.
Figure 14 illustrates how to connect the
FT2232C, when both channels A and B are
configured as 232-style UART interfaces, to
two TTL – RS232 Level Converter I.C.’s to
make a USB <=> Dual Port RS232 converter
using the popular “213” series of TTL to
RS232 level converters. These devices
have 4 transmitters and 5 receivers in a 28-
LD SSOP package and feature an in-built
voltage converter to convert the 5V (nominal)
VCC to the +/- 9 volts required by RS232.
An important feature of these devices is
the SHDN# pin which can power down the
device to a low quiescent current during USB
suspend mode.
The device used in the example above
is a Sipex SP213EHCA which is capable
of RS232 communication at up to 500K
baud. If a lower baud rate is acceptable,
then several pin compatible alternatives
are available such as the Sipex SP213ECA
, the Maxim MAX213CAI and the Analog
Devices ADM213E, which are all good for
communication at up to 115,200 baud. If a
higher baud rate is desired, use a Maxim
MAX3245CAI part which is capable of RS232
communication at rates of up to 1M baud.
The MAX3245 is not pin compatible with
the 213 series devices, also its SHDN pin is
active high, so connect it to PWREN# instead
of SLEEP#. Dual RS232 level converters
such as the Maxim MAX3187 may also be a
suitable alternative.
