Product Introduction
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-timeprogrammable (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 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 higher power source to enable improved charging. Device supplied pre-programmed with unique USB serial number. USB Power Configurations; supports buspowered, self-powered and bus-powered with power switching
- Integrated +3.3V level converter for USB I/O. True 3.3V CMOS drive output and TTL input; Operates down to 1V8 with external pull-ups. Tolerant of 5V input. Configurable I/O pin output drive strength; 4 mA(min) and 16 mA(max).
- Integrated power-on-reset circuit. Fully integrated AVCC supply filtering - no external filtering required.
- UART signal inversion option.
- +5V Single Supply Operation.
- Internal 3V3/1V8 LDO regulators Low operating and USB suspend current; 8mA (active-typ) and 125uA (suspend-typ).
- UHCI/OHCI/EHCI host controller compatible
- USB 2.0 Full Speed capable.
- Extended operating temperature range; -40 to 85°C. Available in compact, Pb-free, 20 Pin SSOP and QFN packages (both RoHS compliant).
