FT232RL
Document No.: FT_000053 FT232R USB UART IC Datasheet Version 2.12 Clearance No.: FTDI# 38 Future Technology Devices International Ltd. FT232R USB UART IC The FT232R is a USB to serial UART interface with the following advanced features: FIFO receives and transmits buffers for high data throughput. Synchronous and asynchronous bit bang interface options with RD# and WR# strobes. Single chip USB to asynchronous serial data transfer interface. Device supplied pre-programmed with unique USB serial number. Entire USB protocol handled on the chip. No USB specific firmware programming required. Supports bus powered, self-powered and highpower bus powered USB configurations. Fully integrated 1024 bit EEPROM storing device descriptors and CBUS I/O configuration. Integrated +3.3V level converter for USB I/O. 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. 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. 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. Low USB bandwidth consumption. Configurable CBUS I/O pins. UHCI/OHCI/EHCI host controller compatible. Transmit and receive LED drive signals. USB 2.0 Full Speed compatible. UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / 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).
