USB 总线转接芯片

CH341是一个USB总线的转接芯片，通过USB总线提供异步串 口、打印口、并口以及常用的2线和4线等同步串行接口。在异步 串口方式下，CH341提供串口发送使能、串口接收就等交 互式的速率控制信号以及常用的MODEM联络信号，用于为计算机扩 展异步串口，或者将普通的串口设备直接升级到USB总线。\n在打印口方式下，CH341提供了兼容USB相关规范和Windows操作系统 的标准USB打印口，用于将普通的并口打印机直接升级到USB总线 。\n在并口方式下，CH341提供了EPP方式或MEM方式的8位并行接口，用于 在不需要单片机/DSP/MCU的环境下，直接输入输出数据。\n除 概述\n• 全速USB设备接口，兼容USB V2.0，外围元器件只需要电容。\n• 可选：通过外部的低成本串行EEPROM定义厂商ID、产品ID、序列号等。\n• 支持5V电源电压和3.3V电源电压。\n• 低成本，直接转换原串口外围设备、原并口打印机、原并口外围设备。\n• 提供SOP28、SSOP20、QFN28三种无铅封装，兼容RoHS。\n• 由于是通过USB转换的接口，所以只能做到应用层兼容，而无法绝对相同。\n异步串口\n• 仿真标准串口，用于升级原串口外围设备，或者通过USB增加额外串口。\n• 计算机端Windows操作系统下的串口应用程序完全兼容，无需修改。\n• 硬件全双工;
