FT231X USB TO FULL HANDSHAKE UART IC Datasheet Version 1.2 Document No.: FT 000565 Clearance No.: FTDI 261 Future Technology Devices International Ltd. FT231X (USB to FULL HANDSHAKE UART IC) USB Battery Charger Detection. Allows for USB The FT231X is a USB to serial UART peripheral devices to detect the presence of a interface with full modem control and higher power source to enable improved the following advanced features: charging. Single chip USB to asynchronous serial data Device supplied pre-programmed with unique transfer interface. USB serial number. Entire USB protocol handled on the chip. No USB Power Configurations supports bus- USB specific firmware programming required. powered, self-powered and bus-powered with power switching Fully integrated 2048 byte multi-time- programmable (MTP) memory, storing device Integrated +3.3V level converter for USB I/O. descriptors and CBUS I/O configuration. True 3.3V CMOS drive output and TTL input Fully integrated clock generation with no Operates down to 1V8 with external pull-ups. external crystal required plus optional clock Tolerant of 5V input. output selection enabling glue-less interface Configurable I/O pin output drive strength 4 to external MCU or FPGA. mA(min) and 16 mA(max). Data transfer rates from 300 baud to 3 Mbaud Integrated power-on-reset circuit. (RS422, RS485, and RS232 ) at TTL levels. Fully integrated AVCC supply filtering - no 512 byte receive buffer and 512 byte transmit external filtering required. buffer utilising buffer smoothing technology to allow for high data throughput. UART signal inversion option. FTDIs royalty-free Virtual Com Port (VCP) + 5V Single Supply Operation. and Direct (D2XX) drivers eliminate the Internal 3V3/1V8 LDO regulators requirement for USB driver development in most cases. Low operating and USB suspend current 8mA (active-typ) and 125uA (suspend-typ). Configurable CBUS I/O pins. UHCI/OHCI/EHCI host controller compatible Transmit and receive LED drive signals. USB 2.0 Full Speed capable. UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space Extended operating temperature range -40 to no parity 85 C. Synchronous and asynchronous bit bang Available in compact, Pb-free, 20 Pin SSOP and interface options with RD and WR strobes. QFN packages (both RoHS compliant).
