CH341A Series Burner Chip Programmer

The CH341A series burner chip programmer is a low-cost mini USB  EEPROM Flash BIOS USB Programmer that was built and designed to support 24 EEPROM and 25 SPI flash 8pin/16 pin chip. This CH341A series programmer is integrated with a powerful CH341A chip that has the ability ro automatically recognize 25 series chip. This CH341A  EEPROM USB programmer is equipped with a indicator lamp that helps the user understand working status of the USB programmer. 

You will require ComboTool app for performing:

  1. Writing & Executing JAVAScript in Android device and performing I/O directly.
  2. Plugin IR_Temper Sensor => Combotool change to be a temperature meter.
  3. Plugin RS485 Converter =>It can capture/send RS485 Modbus frame.
  4. Plugin => It can be a UV meter.

Types of modes used in the CH341A EEPROM USB programmer:

  • UART Mode: The UART mode in the CH341A series USB programmer provides a different control signal rate such as serial transfer enable, serial receive in ready. This mode provides the CH341A USB programmer with common MODEM communication signal in order to expand UART for computer.
  • Printer Port Mode: The standard printer port in the CH341A EEPROM programmer compounds USB relevant protocol and Windows operating system used to upgrade ordinary parallel printer to USB bus directly.
  • Parallel Mode: The CH341A USb programmer provides 8-bit parallel in EPP or MEM mode which can be used to input/output data directly without MCU/DSP.

How do you program a BIOS CH341A chip?

  • You need to first reboot your computer since you need to outside of your normal operating system while entering the BIOS utility.
  • Pay attention to the screen as your computer loads up to press the indicated key during the startup messages to enter the BIOS.
  • Navigate through the BIOS menu screens, using the arrow keys.
  • Highlight the setting to be reprogrammed with the arrow keys and press "Enter". This will display a list of valid settings for the particular option. Highlight the option that you wish to select and press "Enter" again.
  • Exit BIOS when done making your changes by pressing the "Esc" key. Press "Y" to save and confirm your changes.

3. How to use a 25 Series Burner Chip EEPROM BIOS Writer Flash Board Programmer tool?

  • Steps to use a EEPROM BIOS Writer: 
  1. GND: connect to GND
  2. RXD: Connection to MCU.TX (signal flow: MCU.TX >> FT232 >> PC.RX)
  3. TXD: connect to MCU.RX (signal flow: MCU.RX << FT232 << PC.TX)
  4. 3V3/5V: output 3.3V or 5V (module is powered via USB,  jumper should be bridged to 3.3V or 5V)
  5. RTS: connect to MCU.CTS (signal flow: MCU.CTS << FT232 << PC.RTS)
  6. CTS: connect to MCU.RTS (signal flow: MCU.RTS >> FT232 >> PC.CTS)
