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.
