FT232R USB UART IC Datasheet
The FT232R is a USB to serial UART interface FIFO receives and transmits buffers for high with the following advanced features: data throughput. Single chip USB to asynchronous serial data Synchronous and asynchronous bit bang transfer interface. interface options with RD# and WR# strobes. Entire USB protocol handled on the chip. No Device supplied pre-programmed with unique USB specific firmware programming required. USB serial number. Fully integrated 1024 bit EEPROM storing Supports bus powered, self-powered and high- device descriptors and CBUS I/O configuration. power bus powered USB configurations. Fully integrated USB termination resistors. Integrated +3.3V level converter for USB I/O. Fully integrated clock generation with no Integrated level converter on UART and CBUS external crystal required plus optional clock for interfacing to between +1.8V and +5V output selection enabling a glue-less interface logic. to external MCU or FPGA. True 5V/3.3V/2.8V/1.8V CMOS drive output Data transfer rates from 300 baud to 3 Mbaud and TTL input. (RS422, RS485, RS232) at TTL levels. Configurable I/O pin output drive strength. 128 byte receive buffer and 256 byte transmit Integrated power-on-reset circuit. buffer utilising buffer smoothing technology to allow for high data throughput. Fully integrated AVCC supply filtering - no external filtering required. FTDI’s royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the UART signal inversion option. requirement for USB driver development in most cases. +3.3V (using external oscillator) to +5.25V (internal oscillator) Single Supply Operation. Unique USB FTDIChip-ID™ feature. Low operating and USB suspend current. Configurable CBUS I/O pins. Low USB bandwidth consumption. Transmit and receive LED drive signals. UHCI/OHCI/EHCI host controller compatible. UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / USB 2.0 Full Speed compatible. no parity -40°C to 85°C extended operating temperature range. Available in compact Pb-free 28 Pin SSOP and QFN-32 packages (both RoHS compliant).
