Neoprogrammer 21019 Ch341a Exclusive -
NeoProgrammer 2.1.0.19 is a widely used software for the CH341A USB programmer, designed for reading and writing EEPROM and SPI Flash chips. It is an enhanced version of the open-source ASProgrammer project. Core Features of Version 2.1.0.19
4. Blacklist & Whitelist Configuration
One unique feature of v21019 is the ability to blacklist specific chip IDs. If you encounter a counterfeit chip that reports a false ID, you can manually override the software to force a specific read/write algorithm.
🔗 Recommended Settings for Exclusive Mode
- Install WinUSB driver via Zadig (not libusb).
- In NeoProgrammer → Settings → Enable “Fast programming” and “Check ID before operation.”
- Use quality 10kΩ pull-ups on CS/CLK/MOSI for stable long wires.

Refined Detection Algorithms: This version specifically updated the 93Cxx detection algorithm and improved the identification of old SPI components.
The modified chip wasn't just reading the data; it was brute-forcing the encryption on the hardware level. The "Exclusive" nature of the device wasn't just a marketing tag—it was a hardware backdoor installed by a ghost from the past. 21019 wasn't a seller; 21019 was a version number. NeoProgrammer 2
Integrated Connection Guide: Unlike basic tools, it displays a visual diagram showing exactly how to orient the chip on the programmer's pins once a chip model is selected.
Step 2: Remove Old Drivers (Crucial)
Open Device Manager on Windows. Find your CH341A under "USB devices." Right-click and select Uninstall device. Check the box "Delete driver software for this device." This prevents driver conflicts. Install WinUSB driver via Zadig (not libusb)
or perform a voltage modification if working with sensitive components. : To function, the software requires the CH341PAR driver rather than the standard serial driver. in NeoProgrammer if auto-detect fails?
