This USB2.0 Full Speed IC offers a compact bridge to I2C devices. The device is an I2C slave, capable of operating up to 3.4MBit/s, with low power consumption (8mA). The FT201X includes the complete FT-X series feature set and enables USB to be added into a system design quickly and easily over an I2C interface
Key Hardware Features
Single chip USB to I2C interface.
Entire USB protocol handled on the chip. No USB specific firmware programming required.
Fully integrated 2048 byte Multi-Time-Programmable (MTP) memory for 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 pin.
Battery Charger Detection. May be used by mobile devices to detect the presence of a charger on the USB port to enable higher current / faster charging of batteries.
Device supplied pre-programmed with unique USB serial number.
Supports bus powered, self powered and high-power bus powered USB configurations.
Integrated +3.3V level converter for USB I/O.
True 3.3V CMOS drive output and TTL input.
(Operates down to 1.8V with external pull ups and is also 5V tolerant)
