FT232RN

The FT232RN is a USB to serial UART interface

with the following advanced features:

•

Single chip USB to asynchronous serial data

transfer interface.

•

Entire USB protocol handled on the chip. No USB

specific firmware programming required.

•

Fully integrated 1024-bit EEPROM storing device

descriptors and CBUS I/O configuration.

•

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.

•

Data transfer rates from 300 baud to 3 Mbaud

(RS422, RS485, RS232) at TTL levels.

•

128 bytes receive buffer, and 256 bytes transmit

buffer utilising buffer smoothing technology to

allow for high data throughput.

•

FTDI’s royalty-free Virtual Com Port (VCP) and

Direct (D2XX) drivers eliminate the requirement

for USB driver development in most cases.

•

Unique USB FTDIChip-ID™ feature.

•

Configurable CBUS I/O pins.

•

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

•

FIFO receives and transmits buffers for high

data throughput.

•

Synchronous

and

asynchronous

bit

bang

interface options with RD# and WR# strobes.

•

Device supplied pre-programmed with unique

USB serial number.

•

Supports bus powered, self-powered and high-

power bus powered USB configurations.

•

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.

•

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.

•

Fully integrated AVCC supply filtering - no

external filtering required.

•

UART signal inversion option.

•

+3.3V to +5.25V Single Supply Operation.

•

Low operating and USB suspend current.

•

Low USB bandwidth consumption.

•

UHCI/OHCI/EHCI host controller compatible.

•

USB 2.0 Full Speed compatible.

•

-40°C to 85°C extended operating temperature

range.

•

Available in compact Pb-free 28 Pin SSOP and

QFN-32 packages (both RoHS compliant).
