USB 總線轉接芯片

CH341是一個USB總線的轉接芯片，通過USB總線提供異步串 口、打印口、并口以及常用的2線和4線等同步串行接口。在異步 串口方式下，CH341提供串口發(fā)送使能、串口接收就等交 互式的速率控制信號以及常用的MODEM聯(lián)絡信號，用于為計算機擴 展異步串口，或者將普通的串口設備直接升級到USB總線。\n在打印口方式下，CH341提供了兼容USB相關規(guī)范和Windows操作系統(tǒng) 的標準USB打印口，用于將普通的并口打印機直接升級到USB總線 。\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 在不需要單片機/DSP/MCU的環(huán)境下，直接輸入輸出數(shù)據(jù)。\n除 概述\n? 全速USB設備接口，兼容USB V2.0，外圍元器件只需要電容。\n? 可選：通過外部的低成本串行EEPROM定義廠商ID、產(chǎn)品ID、序列號等。\n? 支持5V電源電壓和3.3V電源電壓。\n? 低成本，直接轉換原串口外圍設備、原并口打印機、原并口外圍設備。\n? 提供SOP28、SSOP20、QFN28三種無鉛封裝，兼容RoHS。\n? 由于是通過USB轉換的接口，所以只能做到應用層兼容，而無法絕對相同。\n異步串口\n? 仿真標準串口，用于升級原串口外圍設備，或者通過USB增加額外串口。\n? 計算機端Windows操作系統(tǒng)下的串口應用程序完全兼容，無需修改。\n? 硬件全雙工;
