FT201XS-R

The FT201X is a USB to I2C interface with the following advanced features:

■ Single chip USB to I2C slave interface.
■ Up to 3.4MHz, high speed mode, I2C supported
■ 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.
■ 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.
■ 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.
■ + 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 85⁰C.
■ Available in compact Pb-free 16 Pin SSOP and QFN packages (both RoHS compliant).
