28P/SSOP (ROHS) USB UART IC

FTDI- FT232RL-USB UART IC

 
 
 
Features
 
 

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 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 receive and transmit 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 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. 
●-40°C to 85°C extended operating temperature range. 
●Available in compact Pb-free 28 Pin SSOP and QFN-32 packages (both RoHS compliant).
