FT231X中文资料FT231X – Full Speed USB to Full Handshake UART数据手册FTDI规格书

描述 Description

This USB2.0 Full Speed  IC offersa compact bridge to full handshake UART interfaces. The device is a UART,capable of operating up to 3MBaud, with low power consumption (8mA). The FT231Xincludes the complete FT-X series feature set and enables USB to be added into asystem design quickly and easily over a UART interface

特性 Features

·Singlechip USB to asynchronous serial data transfer interface.
·EntireUSB protocol handled on the chip. No USB specific firmware programmingrequired.
·Fullyintegrated 2048 byte EEPROM for storing device descriptors and CBUS I/Oconfiguration.
