FT231XS-X中文资料飞特帝亚数据手册PDF规格书

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 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 bus- powered, 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 85⁰C.

 Available in compact, Pb-free, 20 Pin SSOP and QFN packages (both RoHS compliant).
