FT232R USB UART IC
FIFO receive and transmit buffers for high data
throughput.
The FT232R is a USB to serial UART
interface with the following advanced
features:
Synchronous and asynchronous bit bang
interface options with RD# and WR# strobes.
Single chip USB to asynchronous serial data
transfer interface.
Device supplied pre-programmed with unique
USB serial number.
Entire USB protocol handled on the chip. No
USB specific firmware programming required.
Supports bus powered, self powered and high-
power bus powered USB configurations.
Fully integrated 1024 bit EEPROM storing
device descriptors and CBUS I/O configuration.
Integrated +3.3V level converter for USB I/O.
Integrated level converter on UART and CBUS
for interfacing to between +1.8V and +5V
logic.
Fully integrated USB termination resistors.
Fully integrated clock generation with no
external crystal required plus optional clock
output selection enabling a glue-less interface
to external MCU or FPGA.
True 5V/3.3V/2.8V/1.8V CMOS drive output
and TTL input.
Configurable I/O pin output drive strength.
Integrated power-on-reset circuit.
Data transfer rates from 300 baud to 3 Mbaud
(RS422, RS485, RS232 ) at TTL levels.
128 byte receive buffer and 256 byte transmit
buffer utilising buffer smoothing technology to
allow for high data throughput.
Fully integrated AVCC supply filtering - no
external filtering required.
UART signal inversion option.
FTDI‟s royalty-free Virtual Com Port (VCP) and
+3.3V (using external oscillator) to +5.25V
(internal oscillator) Single Supply Operation.
Direct
(D2XX)
drivers
eliminate
the
requirement for USB driver development in
most cases.
Low operating and USB suspend current.
Low USB bandwidth consumption.
Unique USB FTDIChip-ID™ feature.
Configurable CBUS I/O pins.
UHCI/OHCI/EHCI host controller compatible.
USB 2.0 Full Speed compatible.
Transmit and receive LED drive signals.
UART interface support for 7 or 8 data bits, 1
or 2 stop bits and odd / even / mark / space /
no parity
-40°C to 85°C extended operating temperature
range.
Available in compact Pb-free 28 Pin SSOP and
QFN-32 packages (both RoHS compliant).
