Connect the test clip to bios chip. Connect ch341a programmer to USB. Run CH341A_c.exe from CH341A programm v1. uncheck "Erase" Win-Raid Forum
这是CH341A用户最容易踩的坑。许多CH341A编程器默认输出，但绝大多数现代SPI闪存芯片仅支持 3.3V 。如果将5V直接送到3.3V芯片上， 芯片几乎瞬间烧毁 。
Using transforms the CH341A. It stabilizes the connection, unlocks thousands of chips, adds debugging features, and gives you a visual buffer editor. For 99% of computer repair technicians, hobbyists, and data recovery specialists, this software/hardware combo is the best $5 you will ever spend.
NeoProgrammer is a specialized application designed to interface with the CH341A USB programmer. While tools like AsProgrammer are good, NeoProgrammer (an evolution of other community-driven tools) focuses on providing robust support for a vast library of (EEPROM and SPI Flash). neoprogrammer 21 019 ch341a best
Sometimes the chip is locked. Try checking "Ignore ID" or checking the "Write" settings to ensure the chip is properly erased before writing. Conclusion
Right-click and execute SETUP.EXE as an Administrator, then click .
First, it offers an . Version 2.1.0.19 includes definitions for thousands of SPI flashes, EEPROMs (24C, 93C series), and even some microcontrollers. You rarely need to manually enter chip IDs; the software identifies the chip instantly. Connect the test clip to bios chip

So, how does the Neoprogrammer 21 019 CH341A compare to other programmers on the market? Here's a brief comparison:
Later versions (2.2.x.x) introduced a completely new, encrypted chip database format. While this allowed for database updates to add new chips without recompiling the software, it broke compatibility with the older chiplist.xml files that users had manually created for obscure chips. Many users stuck with V2.1.0.19 because of its plain-text XML database, which allows users to directly edit and add custom chip definitions.
