TTL-232R TTL TO USB SERIAL CONVERTER RANGE OF CABLES Datasheet Version 2.02
Clearance No.: FTDI# 53
2.2 Features
TTL-232R Converter Cable provides a USB to
TTL Serial interface with various end
connectors.
On board FT232RQ provides single chip USB to
asynchronous serial data transfer interface.
Entire USB protocol handled by the electronics
in the cable USB.
Connect directly to a microcontroller UART or
I/O pins.
UART interface support for 7 or 8 data bits, 1
or 2 stop bits and odd / even / mark / space /
no parity.
Fully assisted hardware (RTS#/CTS#) or X-On
/ X-Off software handshaking.
Data transfer rates from 300 baud to 3 Mbaud
at TTL levels.
Internal EEPROM with user writeable area.
5V CMOS drive outputs and 5V safe TTL inputs
makes the TTL-232R easy to interface to 5V
MCU‟s.
FTDI‟s royalty-free VCP allow for
communication as a standard emulated COM
port and D2XX „direct‟ drivers provide DLL
application programming interface.
Support for FT232R FTDIChip-ID™ feature for
improved security.
+5V or +3.3V output allows external logic to be
powered from the USB port.
6 way outputs provide Tx, Rx, RTS#, CTS#,
VCC and GND (except Audio Jack which
provides only TX,RX and GND).
8 way, keyed connector to support FTDI
VDRIVE2 and VMUSIC2.
3 way Audio Jack connector provides Tx, Rx
and GND.
Low USB bandwidth consumption.
UHCI / OHCI / EHCI host controller compatible.
USB 2.0 Full Speed compatible.
-40°C to +85°C operating temperature range.
Cable length is 1.80m (6 feet).
FCC and CE compliant.
Custom versions also available (subject to
MOQ).
