FT231X集成電路（IC）的控制器規(guī)格書PDF中文資料

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 85?C.

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