FT232R - USB to UART

FT232R - USB to UART
The FT232R 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 ena-
bling a glueless interface to an 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 utilizing 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.
• 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
• 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 (using external oscillator) to +5.25V (internal oscillator) 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
