描述 Description

This USB2.0 Full Speed? IC offersa compact bridge to I2C?devices. The device is an I2C slave, capable of operating upto 3.4MBit/s, with low power consumption (8mA). The FT201X includes thecomplete FT-X series feature set and enables USB to be added into a system designquickly and easily over an I2C interface

特性 Features

·Singlechip USB to I2C interface.
·EntireUSB protocol handled on the chip. No USB specific firmware programmingrequired.
·Fullyintegrated 2048 byte Multi-Time-Programmable (MTP) memory for storing devicedescriptors and CBUS I/O configuration.
