The FT232RQ is a 32-pin QFN with an RoHS-compliant lead-free package (the FT232RQ is not available in a standard leaded package); it has an internal EEPROM, clock and passive components. 

 Features:

• Single chip USB to asynchronous serial data transfer interface.
• Entire USB protocol handled on the chip - No USB-specific firmware programming required.
• UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity.
• Fully assisted hardware or X-On / X-Off software handshaking.
• Data transfer rates from 300 baud to 3 Megabaud (RS422 / RS485 and at TTL levels) and 300 baud to 1 Megabaud (RS232).
• 256 byte receive buffer and 128 byte transmit buffer utilizing buffer smoothing technology to allow for high data throughput.
• In-built support for event characters and line break condition.
• USB FTDIChip-ID™ feature.
• Configurable CBUS I/O pins.
• Auto transmit buffer control for RS485 applications.
• Transmit and receive LED drive signals.
• 48MHz, 24MHz,12MHz, and 6MHz clock output signal Options for driving external MCU or FPGA.
• FIFO receive and transmit buffers for high data throughput.
• Adjustable receive buffer timeout.
• Synchronous and asynchronous bit bang mode interface options with RD# and WR# strobes.
• CBUS bit bang mode option
• Package Type: QFN-32
