FT232 USB to TTL chip

Want to convert TTL data into USB & vice versa? Well then this FT232 USB to serial converter IC is perfect for you. 

Features of FT232

• 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 byte receive buffer and 256 byte 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 highpower 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.
