FT232BL是一种接口转换芯片,可以实现USB到串行UART接口的转换,也可转换到同步、异步Bit-Bang接口模式。提供各种操作系统(OS)下的驱动程序。设计简单,使用方便,兼容性好:
        1、芯片整合了EEPROM,可用于IO的配置以及存储USB VID序列号和产品描述信息(PID)。节约成本。
        2、芯片整合了电平转换器,使得其I/O口电平支持5V2.8V的宽范围;
        3I/O管脚驱动能力强,可驱动多个设备或者较长的数据线;
        4、芯片内部整合了上电复位电路,节约成本;
        5、芯片能自行产生时钟,无需外挂晶振钟振,节约成本;
        6、内部集成了电源去耦RC电路;
        7、此芯片符合RoHS标准
