FT201X数据手册集成电路（IC）的控制器规格书PDF

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.
·Fullyintegrated clock generation with no external crystal required plus optionalclock output selection enabling a glue-less interface to external MCU or FPGA.
·512 bytereceive buffer and 512 byte transmit buffer utilising buffer smoothingtechnology to allow for high data throughput.
·FTDI’sroyalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate therequirement for USB driver development in most cases.
