Frequently Asked Questions

Q: What chips are compatible with the CH341A USB BIOS EEPROM Programmer?

A: The CH341A programmer supports a wide range of 24CXX series EEPROM chips as well as many SPI flash chips commonly found in BIOS/UEFI motherboard chips. It is compatible with both SOIC8 and DIP8 package formats, making it suitable for most common flash and EEPROM IC types used in computers and embedded electronics.

Q: Do I need to desolder the chip to use the SOIC8 SOP8 test clip?

A: No — the included SOIC8/SOP8 clip-on test clip is specifically designed for in-circuit programming. Simply clip it onto the target chip while it is still soldered to the board, connect the ribbon cable to the CH341A programmer, and proceed with your read/write operation using your preferred programmer software.

Q: What software works with the CH341A USB EEPROM Programmer?

A: The CH341A is compatible with several popular and freely available programmer applications, including AsProgrammer, NeoProgrammer, and CH341A Programmer software. These tools allow you to read, write, verify, and erase supported EEPROM and flash chips with a straightforward interface on Windows-based systems.

Q: What voltage should I select when programming a chip?

A: The CH341A programmer supports both 3.3V and 5V operating voltages. Always check your target chip's datasheet to confirm the correct operating voltage before connecting. Using the wrong voltage can damage the chip, so verifying this step is essential for safe and accurate programming.
