FT231X USB TO FULL HANDSHAKE UART IC Datasheet Version 1.4 Document No.: FT_000565 Clearance No.: FTDI# 261 Future Technology Devices International Ltd. FT231X (USB to FULL HANDSHAKE UART IC) The FT231X is a USB to serial UART interface with full modem control and 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 2048 byte multi-time- programmable (MTP) memory, storing device descriptors and CBUS I/O configuration.   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, and RS232) at TTL levels.   512 byte receive buffer and 512 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   Synchronous and asynchronous bit bang interface options with RD# and WR# strobes.  USB Battery Charger Detection. Allows for USB peripheral devices to detect the presence of a...
