    Description

    CH341 is an USB interface chip that can emulate UART communication, standard parallel port, memory parallel port and synchronous serial (I2C, SPI). The chip is manufactured by Chinese company Jiangsu QinHeng Ltd. CH341 is used by some cheap memory programmers. The IC is somehow limited in this configuration, because the programmer makes use only of the SPI and I2C interface and leaves a lot of pins unconnected. Featured By RoboticsBD.

    A quick look at the board reveals the main electronic parts used: CH341, a 12 MHz crystal required by the chip, a 3.3V regulator, two 7 pin headers and the ZIF (zero insertion force) socket. The programmer can be bought with additional sockets and adapters, some of them with voltage shifting circuits.

    This low-cost mini USB CH341 24 25 Series EEPROM Flash BIOS USB Programmer is intended to support 24xx Series EEPROM and 25xx series SPI flash 8pin/16 pin chip. It is equipped with CH 341A chip, can automatically recognize 25 series chip, and its 24/25 series indicator lamp enables the user to easily recognize module’s working status. This awesome programmer is also user-friendly because it supports USB to TTL conversion and the SOP8 SOP16 to DIP8 converter board makes the connection with different chips easily.

    CH341 is a USB bus convert chip, providing UART, printer port, parallel and synchronous serial with 2-wire or 4-wire through USB bus. In UART mode, CH341 provides alternant rate control signals such as serial transfer enable, serial receive in ready etc. It also supplies common MODEM communication signal in order to expand UART for computer or upgrade common synchronous interface device to USB bus directly.

    In printer port mode, CH341 supplies standard USB printer port which compounds USB relevant protocol and Windows operating system used to upgrade ordinary parallel printer to USB bus directly. In parallel mode, CH341 gives out 8-bit parallel in EPP or MEM mode. It can be used to input/output data directly without MCU/DSP. Besides, CH341 also supports some common synchronous serial such as 2-wire (SCL, SDA) and 4-wire (CS, SCK/CLK, MISO/SDI/DIN and MOSI/SDO/DOUT) interface.
