FTDI FT230XS-R

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-timeprogrammable (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. 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 compatible. Extended operating temperature range; -40 to 85°C. Available in compact Pb-free 16 pin SSOP and 16 pin QFN packages (both RoHS compliant).
