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 utilizing 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 for 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.
