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-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.
