Step 3: The Firmware "Link" for CH341A (Optional but Recommended)
The CH341A itself has internal firmware. The 21019 software works best with CH341A chips that have EEPROM version 3.0.0 or higher. Most black PCBs (rev C) work perfectly. Avoid the transparent blue PCB (rev A) – it has a 5V logic level that kills 1.8V chips. neoprogrammer 21019 ch341a link
: Ensure you have the CH341PAR (parallel/interface) driver installed; otherwise, the software won't detect the USB device even if it's plugged in. These videos demonstrate how to set up and
- Click "Read ID". You should see
0xEF 0x40 0x17(example for Winbond). - If you see
0xFF 0xFF 0xFF, the clip has no connection.
- Right-click
NeoProgrammer.exe→ Run as Admin. - Select "CH341A" from the Device dropdown.
- Select "SPI" as the interface.
- For Windows: CH341A programmer GUI steps.
- For Linux/macOS: flashrom command example; device node detection.
- SPI Flash: 24 series (I2C) and 25 series (SPI), such as W25Q64, MX25L3205, EN25QH64.
- 24 EEPROM: 24C01, 24C02, etc.
- 25 EEPROM: SST25VF series.
Experimental Support: It includes experimental capabilities for SPI NAND and specialized components like ENE KB90xx Super IO chips. Click "Read ID"
