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、串口接收就绪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。

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。

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。

除此之外，CH341B/F/A芯片还支持一些常用的同步串行接口，例如2线接口（SCL线、SDA线）和4线接口（CS线、SCK/CLK线、MISO/SDI/DIN线、MOSI/SDO/DOUT线）等。

产品特点

全速USB设备接口，兼容USB V2.0，外围元器件只需要电容。
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。
支持5V电源电压和3.3V电源电压。
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。
提供SOP-28、SSOP-20、QFN28三种无铅封装，兼容RoHS。
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。

异步串口

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。
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。
硬件全双工串口，内置收发缓冲区，支持通讯波特率50bps～2Mbps。
支持5、6、7或者8个数据位，支持奇校验、偶校验、空白、标志以及无校验。
支持串口发送使能、串口接收就绪等传输速率控制信号和MODEM联络信号。
通过外加电平转换器件，提供RS232、RS485、RS422等接口。
支持以标准的串口通讯方式间接地访问CH341外挂的串行EEPROM存储器。

打印口

标准USB打印口，用于升级原并口打印机，兼容相关的USB规范。
兼容Windows操作系统，在Windows 2000和XP下无需驱动程序，应用程序完全兼容。
支持各种标准的并口打印机，可选低速打印方式和高速打印方式。
支持IEEE-1284规范的双向通讯，支持单向和双向传输打印机。

并口

提供两种接口方式：EPP方式和MEM方式。
EPP方式提供AS#、DS#、WR#等信号，类似于EPP V1.7或EPP V1.9。
MEM方式提供A0、RD#、WR#等信号，类似于存储器读写方式。

同步串口

采用FlexWireTM技术，通过软件能够实现灵活多样的2线到5线的同步串口。
作为Host/Master主机端，支持2线和4线等常用的同步串行接口。
2线接口提供SCL和SDA两个信号线，支持4种传输速度。

产品封装

注：

CH341C/T仅用于USB转串口或者USB转2线接口。
CH341H仅用于USB转4线接口等（例如SPI），新设计不推荐使用，建议用CH341B或CH341F。
CH341A、CH341T和CH341H必须外接晶体及振荡电容。
CH341B、CH341F和CH341C既可以选择外接晶体及电容，也可以选择不外接而直接使用内置时钟。

STM32+SD NAND，替代Nor Flash的优势之选

SD NAND与正点原子精英板的连接由于正点原子精英板没有SD NAND接口，只有TF卡接口，所以SD NAND需要用到转接板来连接。SD NAND正常运行现象本次实验的程序是正点原子的SD卡实验例程，先用读卡器把SD NAND接到电脑上，并复制一个文件进去，再插到开发板上；用送的数据线连接USB UART接口，下载好程序，打开电脑上的串口助手，按下KEY0，即可读取到数据。
