The "21 019" reference in keywords usually points to a specific database update from early 2021 that added critical features:
Click the button to verify that the software communicates with the hardware. Step 3: Backing Up the Original BIOS (Crucial) Never flash a new BIOS without backing up the original.
If you want, I can:
: After writing, use the "Verify" function. This compares the chip's current content with your file to ensure there were no errors during transmission. Important Safety Tips
: It works with a vast range of chips including SPI NOR flash , I2C EEPROMs (24Cxx) , MicroWire (93Cxx) , and even experimental support for SPI NAND .
As of 2025-2026, the CH341A is still in production, and Neoprogrammer 21 019 remains the most stable build. Newer versions (22xxx, 23xxx) introduced UI bugs and reduced chip support. The "21 019 full" release is considered the . neoprogrammer 21 019 ch341a full
Once these are ✅, you can safely read, erase, and program.
Disclaimer: Always ensure you have a legal right to modify the firmware of the device you are working on. Modifying BIOS or firmware carries a risk of permanent damage (bricking) if not performed correctly.

Neoprogrammer 21.019 is a Windows utility for SPI/NAND/NOR flash and EEPROM chips often paired with low-cost CH341A USB programmer hardware. This guide shows how to install drivers, connect the CH341A, read/write common chips, verify images, and resolve frequent issues.
: Many CH341A "black edition" programmers output 5V on data lines, which can damage 3.3V chips. Some technicians recommend a voltage modification or using the "green" version.
