FT201X
(USB I2C SLAVE IC)
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-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.
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 buspowered, 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).
