Item# FT232RL
$3.75, 10/$33.80, 100/$300.00

Product Description:

This is a popular USB to UART converter IC. They are on many popular product (i.e. Arduino and many more). This is a 28-pin SSOP package version. It can be soldered by hand or you can get an assembled breakout board here.

Check out these really well done tutorials on bit-banging SPI with the FT232. Nice work Michael!

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.
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.
-40C to 85C extended operating temperature range.
