DESCRIPTION

· The FT232BM is a single-chip USB to asynchronous serial data transfer interface.

· It integrates a USB to serial UART interface with advanced features for various communication protocols.

FEATURES

· Full handshaking and modem interface signals.

· Adjustable RX buffer timeout and fully assisted hardware or X-On/X-Off handshaking.

· In-built support for event characters and line break conditions.

· Auto Transmit Buffer control for RS485.

· Supports USB Suspend/Resume through SLEEP# and RI# pins.

· High power USB Bus powered devices support through PWREN# pin.

· Data transfer rates from 300 baud to 3 Mbaud (RS422, RS485, RS232) at TTL levels.

· 384 byte receive buffer and 128 byte transmit buffer with buffer smoothing technology.

· UART interface supports 7 or 8 data bits, 1 or 2 stop bits, and various parity options.

· Integrated level converter for 5V and 3.3V logic interfacing.
