The FT230X is a USB to serial UART interface withoptimised pin count for smaller PCB designs and thefollowing advanced 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 / noparity.

• 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 improved charging.

• Device supplied pre-programmed with unique USBserial number.

• USB Power Configurations; supports bus- powered,self-powered and bus-powered with powerswitching.

• 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 externalfiltering required.

• UART signal inversion option.

• + 5V Single Supply Operation.

• Internal 3V3/1V8 LDO regulators.

• Low operating and USB suspend current;8mA (active-typ) and 125µA (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).
