The FT230X is a USB to serial UART interface with optimised pin count for smaller PCB designs 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 a 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.
●• 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 70uA (suspend-typ).
●• UHCI/OHCI/EHCI host controller compatible.
●• USB 2.0 Full Speed compatible.
●• Extended operating temperature range; -40 to 85⁰C.
●• Available in compact Pb-free 16 pin SSOP and 16 pin QFN packages (both RoHS compliant).
