TTL-232R-PCB TTL TO USB SERIAL CONVERTER PCB Datasheet Version 1.01
Clearance No.: FTDI# 54
2.2 Features
TTL-232R_PCB provides a USB to TTL Serial
UART interface.
On board FT232RQ provides single chip USB to
asynchronous serial data transfer interface.
Entire USB protocol handled by the electronics
on the PCB.
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.
Selectable +3.3V or +5V CMOS drive outputs
and 5V safe TTL inputs makes the TTL-
232R_PCB 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.
PCB is USB Powered - no external supply
required.
+5V or +3.3V output allows external logic to be
powered from the USB port.
6 outputs provide Tx, Rx, RTS#, CTS#, VCC
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.
