Description：

The FT230X is a USB to serial UARTinterface with optimised pin count forsmaller PCB designs and the followingadvanced features:

 Single chip USB to asynchronous serial datatransfer interface.

 Entire USB protocol handled on the chip. No USBspecific firmware programming required.

 Fully integrated 2048 byte multi-timeprogrammable (MTP) memory, storing devicedescriptors and CBUS I/O configuration.

 Fully integrated clock generation with no externalcrystal required plus optional clock output selectionenabling a glue-less interface to external MCU orFPGA.

 Data transfer rates from 300 baud to 3 Mbaud(RS422, RS485, and RS232) at TTL levels.

 512 byte receive buffer and 512 byte transmitbuffer utilising buffer smoothing technology toallow for high data throughput.

 FTDI’s royalty-free Virtual Com Port (VCP) andDirect (D2XX) drivers eliminate the requirementfor 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 2stop bits and odd / even / mark / space / no parity

 Synchronous and asynchronous bit bang interfaceoptions with RD# and WR# strobes.

 USB Battery Charger Detection. Allows for USBperipheral devices to detect the presence of ahigher power source to enable improvedcharging.

 Device supplied pre-programmed with uniqueUSB 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 - noexternal 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 compatible.

 Extended operating temperature range; -40 to85⁰C.

 Available in compact Pb-free 16 pin SSOP and 16pin QFN packages (both RoHS compliant).
